Product OverviewThis section describes the basic operational essentials for the Serveron On-Line TransformerMonitor TM series and the most common methods of collecting data.

The On-Line Transformer Monitor technology from Serveron Corp. is a remotely deployedlaboratory grade gas chromatograph which can be safely installed onto an energized or non-

energized transformer. The purpose of this monitor is to detect and measure fault gases foundin electrical power transformer s insulating oil. This monitor is designed and constructed toresist environmental conditions relevant to a transformer substation.

The On-Line Transformer Monitor is a precision device. The heart of the monitor is a speciallyconstructed gas chromatograph designed to measure fault gases. Serveron offers two versionsof products, application dependant. The TM8 measures eight IEEE recommend fault gases-hydrogen (H2), oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), methane (CH4),ethylene (C2H4), ethane (C2H6), and acetylene (C2H2). The TM3 measures the three DuvalTriangle fault gases- methane (CH4), ethylene (C2H4), and acetylene (C2H2). The On-LineTransformer Monitor may be used on conservator or nitrogen blanketed transformers howeverin all cases the sample of gas is extracted directly from the oil within the transformer.

Oil is circulated from transformer, to the monitor, and then returned to the transformer through-inch O.D. stainless steel tubing. Stainless steel tubing is used in conjunction with compressionfittings to minimize the risk of leaks. The monitor is outfitted with an internal gas extractionsystem which removes dissolved gases from the circulating transformer oil. Helium is used as acarrier gas to help transport the extracted sample gases through the gas chromatograph. The oilcirculation and gas extraction paths in the On-Line Transformer Monitor are shown below.

Data is collected in the monitor each time a gas chromatograph (GC) analysis is completed. TheGC analysis takes approximately 40 minutes. Once an analysis has been completed, the optionalServeron Monitoring Service (SMS) or TM View software can be used to view the monitors

data. The monitor is set up to perform a sample analysis once every four hours (default). Alldata captured during an analysis is stored on compact flash memory within the monitor. Thecompact flash memory holds approximately (2) years of data. The TM View software orServeron Monitoring Service (SMS) will allow the end user to track the gas ppm levels over timeand monitor the gas levels against user defined caution and alarm settings.

The On-Line Transformer Monitor includes Ambient Temperature and LoadGuide sensingdevices. An optional Oil Moisture andTemperature sensor is available along withspare 4-20ma inputs for use with otherexternal devices. External sensor informationcan also be correlated with fault gas

information to allow a complete diagnosticoverview of the transformerscondition.

Choosing an Oil Supply and Return PortThe On-Line Transformer Monitor removes oil from the transformer, analyzes the oil, and thenreturns the oil to the transformer. The locations where the oil is removed (oil supply port) andreturned (oil return port) are vital for the accurate analysis of the gases within your transformer.

Typically, oil is removed at the top of the transformer, and returned at the bottom of thetransformer. The location of the oil supply port should produce a sample that is a well-mixedrepresentation of the transformer oil. In this section we will discuss how to select the locationsand what fittings are required.

CAUTION: Maximum Oil Inlet Pressure to the monitor is 45 psi (3 bar)

Oil Supply Port

An Oil Supply Assy, part # 456-0026-XX, is provided with the TM monitor. The assemblyconsists of a 2 black iron tee, 2 x reducing bushing, plug, ball valve, and a NPT xTube fitting (see figure 3). The assembly is integral to the installation and commissioningprocess to help remove air and bubbles from entering into the transformer tank when thetransformer oil supply port is opened.

It is important to sample oil from a location on the tank where the oil is constantly mixing inorder to provide a well-mixed representation of oil within the transformer. Typically a top tankvalve is used for the oil supply. For Nitrogen blanketed transformers the oil supply port mustbe at least 6 below the transformers oil level at all times. If the optional Moisture and OilTemperature sensor is to be installed, please refer to the Moisture and Oil Temperature Sensorsection below for additional configuration of the oil supply port.

1) Select an appropriate oil supply port on the transformer

2) Verify the port valve is closed and remove any plugs or caps securing the end of theport

3)

Thoroughly clean the inside of the port of any residue or pipe sealing compound4) Determine the thread size of the selected oil supply port

5) Purchase the necessary nipple and reducing bushing, as required tomount the 2 Oil Supply Assy, part # 456-0026-XX. Note:Dependingon the Oil Supply Port valve size, alternate parts can be purchased insteadof using the 2 assembly provided. If parts are purchased for the transformervalve size, they must be black iron, brass or stainless steel and the street sideto the tee should be NPT.

6) Install nipple and reducing bushing as required to the oil supplyport using Teflon tape or pipe dope. Note: It is important for the

street side of the tee be oriented in the vertical direction

Serveron does not recommend sampling oil from cooling loops orpressurized oil passages; doing so may void the warranty.

Bleed Fixture/Oil Return PortTypically the bottom drain valve is used for the oil return port. The return port should not belocated on the transformer cooling system or any pressurized oil passage. An air bleed fixtureand bubble trap is required at the oil return port to allow air removal during commissioning ofthe monitor. This fixture is referred to as a Bleed Fixture. The Bleed Fixture assembly isincluded with the TM monitor.

1) Select an appropriate oil return port on the transformer

2)

Verify the port valve is closed and remove any plugs or caps closing the end of theport

3) Thoroughly clean the inside of the port of any residue or pipe sealing compound

4) Determine the thread size of the selected oil return port

5) Acquire necessary fittings to attach the bleed fixture to the oil return port

Note: The Serveron Bleed Fixture is designed to fit on a 2 NPT nipple. When usingtheServeron Bleed Fixture, adapt the oil return port to accommodate a 2NPT female thread.

6) Secure the bleed fixture to the oil return port using Teflon tape or pipe dope

Serveron does not recommend sampling oil from cooling loops or pressurized oil

passages; doing so may void the warranty.

Choosing a Mounting LocationThe monitor should be located in a position where it will not interfere with transformermaintenance or access requirements. The front of the monitor must be accessible forcommissioning and maintenance. There at two types of mounting types for the TM monitors;pedestal mounting stand or transformer mounting kit.

Items to consider when choosing a location for the monitor are:

Location of oil supply and oil return ports Location of power supply

Transformer maintenance points

Access to the monitor

Mounting of the monitor stand

The monitor must be mounted and operated in an upright position. Failure to doso will void the warranty.

Mounting StandThe Mounting Stand is a post style, requiring some assembly, and is intended to be mounted to

a concrete pad. The hardware required for assembly and fastening to the concrete pad areincluded. Figure 5 illustrates a typical mounting. See the appendix for mounting and layoutdimensions. For stand assembly, refer to the On-Line Transformer Monitor Installation Guide,part # 810-1644-XX.

Mounting the Stand to a Concrete Pad1) Position the stand in the predetermined mounting location

2) Using the stand as a template, mark four holes onto the

concrete pad

3)

Remove the stand and drill four 3/8-inch x 3-inch deep holesin the marked locations

4) Insert the four 3/8-inch concrete anchors included with thestand into the holes

5) Position the stand over the four mounting bolts and securethe stand checking to make sure the stand is plumb and level

6) Tighten retaining nuts/concrete anchors

Determining need for Oil Inlet CoolerThe On-Line Transformer Monitor operates with transformer inlet oil temperatures rangingbetween 0C to +55C. If your transformer oil temperature frequently deviates outside of thisrange please notify the Serveron technical support team for assistance in determining whetheror not an Oil Inlet Cooler is needed.

Choosing a Communication Interface & ProtocolThe On-Line Transformer Monitor offers a range of communication options. The monitor cancommunicate over multiple interfaces and protocols simultaneously. The differentcommunication options are as follows:

Internal modem - connects to any standard analog phone line (POTS).

RS-232 - connection is provided to allow serial communications with an externalcomputer as well as interface to a cellular or external modem.

RS-485 - connection is provided.

Ethernet connection can be configured as DHCP or a static IP address. The monitoris supplied with a copper interface. A fiber optic interface kit can be purchasedusing Serveron part # 900-0062-XX.

Modbus or DNP3 connection can be configured over all hardware interfacesincluding Ethernet, RS-232, RS-485, and modem. For more information regardingthese protocols, please contact Serveron Technical Support.

An active communication channel is required for Serveron Monitoring Service (SMS) or to enableServeron access for remote calibration and troubleshooting. All communications require an authenticatedusername and password.

Connections - Power, Sensor and Communication cablesThe standard monitor package includes (3) short cables used in conjunction with the Serveron

Junction Box. If longer cables are required, 23 ft cables can be purchased as an option using

Serveron part # 900-0063-XX. Typically these cables are terminated at the junction box terminalstrip that is included with the standard monitor package or at the transformer control cabinet.If the junction box was not purchased, a terminal strip will be required for cable termination. A27-position terminal strip is recommended for flexibility of wiring connections. Depending onthe wiring connections used, a larger terminal strip maybe required. See the appendix for therecommended wiring diagram.

LoadGuideThe On-line Transformer Monitor LoadGuide can be used to correlate transformer load totransformer gassing. The LoadGuide sensor consists of a current clamp that is placed over a 0 to5 amp high or low side CT. It is important that the CT give a good representation of total

transformer load. Transformer load will be displayed on a relative scale with 0 indicating noload and 100% indicating full load. The standard cable length is 8 ft. Additional cable of 22AWG or larger can be added to the LoadGuide sensor cable if required.

Oil Moisture and Temperature (optional)An optional sensor is available to provide oil moisture in parts per million (ppm) or as percentrelative saturation (%RS) and oil temperature (C). Depending on the location of the sensor, theoil temperature can be representative of top oil temperature. It is recommended the OilMoisture and Temperature Sensor be installed on the top valve of the transformer. Thenecessary adapters are provided with the moisture sensor to install the moisture sensor at theOil Supply Assy. If the moisture sensor will be installed in an alternative location, a reducing

bushing made from black iron, brass, or stainless steel may be required.

Helium CylinderThe helium gas cylinder should be securely mounted to the On-line Transformer Monitormounting stand or some other permanent surface. A mounting bracket that meets allcompressed gas cylinder restraining requirements is provided. Serveron also provides thenecessary 1/8-inch O.D. SS-tubing to connect the helium cylinder to the monitor.

Ordering HeliumHelium carrier gas is vital to the performance of the chromatograph within the On-LineTransformer Monitor. Using helium that does not meet the described specifications willsubstantially reduce the life of the monitor and void the warranty. See the appendix forordering information.

Ordering Stainless Steel Tubing and Required FittingsStainless steel tubing is used to connect the monitor to the transformer for circulating thetransformer oil for measurement. The amount of tubing you will need to purchase is based onthe location of your monitor in relation to the valves on your transformer.

Note: Stainless steel is the only material that should be used. The use of any other tubingmaterial will void the warranty of your monitor.

It is recommended that the tubing between the transformer and the monitor be installed as onecontinuous piece, reducing the possibility of oil leaks.

Listed below are items to consider when choosing where to route the tubing to the monitor: Make sure tubing will not interfere with regular maintenance of the transformer

Avoid long unsupported tubing runs

Route tubing so that it will not be tripped over or damaged by activities in the

vicinity of the transformer

If the length of the oil supply or return path exceeds 20-feet, a 1/4-inch stainless steelunion will have to be purchased and on site at the time of installation

It is recommended that your tubing be secured every 2~4-feet using stainless steelcable ties or other adequate clamps

Carefully measure the predetermined tubing route from the transformer oil supply port to themonitor. Take into consideration any corners or other obstacles that may add to the overalllength of tubing. Tubing is typically supplied in 20-foot lengths and will require a union if anysection exceeds 20-feet. Determine the number of 20-foot lengths and unions required for theinstallation. If the overall tubing length exceeds 50-feet supply and return contact serveron forassistance.

Tubing and fittings must be on sight the day of installation. See the appendix for orderinginformation.
