The MPD 500 acquisition unit should be placed as close as possible to the coupling capacitor (Ck) and the test object.

Fiber optical cables (marked orange) connect the test set-up to the control PC and provide complete electrical insulation. Fiber optical cables used with the MPD 500 may be up to 2 km in length.

Substitute the battery back with the power supply if desired.

1.3 Functional Components of the MPD 500

1.3.1 LED Functions

Each MPD 500 unit is equipped with 2 LEDs for displaying the unit’s status. The red LED indicates both the power supply status as well as the status of the fiber optical link. A flashing red LED indicates that the MPD 500 has power and is ready to be connected to a computer via optical fiber. Once the MPD 500 is connected to a computer, and the computer is running the mtronix software, the red LED stops flashing and instead remains continuously on. This indicates that the MPD 500 has a good connection to the computer, and that it can receive data on the fiber optical link without any problems.

As soon as the computer has detected and configured all connected MPD 500 units, the green LED on each unit is turned on. This indicates that the MPD 500 is ready to perform measurements.

1.3.2 Connectors - Front Side

Each MPD 500 is equipped with two sets of fiber optical connectors. Each set of connectors consists of two plugs, marked red and black, respectively. The first set of FO connectors is marked with a computer icon. This connector set is used for the "upstream" FO link (i.e. the link that connects this unit to the computer or the next unit that is nearer to the computer).

The second set is marked with a unit icon, and is used to connect the "downstream" link, i.e. any additional MPD 500 units.

0


The power plug, marked with the word Power, is used to connect the MPP 600 battery pack or a power supply.

Figure 1-2 MPD 500 front panel with LEDs and fiber optical connectors

1.3.3 Connectors - Back Side

There are two BNC inputs, marked V and PD, respectively. Those correspond to the BNC outputs found on the CPL542 and CPL543 quadripoles. The V output on the quadripole must be connected to the V input on the MPD 500. Likewise,

Fiber optical connectors LEDs

the PD output on the quadripole must be connected to the PD input on the MPD 500. If no external quadripole is used, the coupling capacitor must be directly connected to the PD input, and the V input must be left open.

Figure 1-3 MPD 500 back panel

1.3.4 MCU 5xx - LED Functions

All mtronix control units (MCU 550, MCU 502, MCU 504) are equipped with a blue LED that indicates the status of the control unit.

2


When lit, the unit is connected to a computer, has good power, and has been configured for use on the computer. A flashing LED indicates a hardware or software problem with the MCU or the connected computer. If you encounter a flashing LED, please contact Technical Support.

Figure 1-4 MCU 5xx LED functions

Note: The mtronix software requires a lot of computing power. Therefore, when using the mtronix software on a laptop, please be sure to set your laptop to maximum performance. This can be done by left-clicking on the battery (or power plug) symbol in the task notification area and selecting “Always on” or “Maximum performance” as the power plan. Depending on the selected combination of options of the software and/or the duration of the measurement task, it is useful to use the laptop only with a power supply.

5.4.2 Gate Display

In the Gate display, you can draw rectangles on the PD histogram that are interpreted as phase-amplitude gates. Phase-amplitude gates define a rectangular area within the phase-resolved display that should be excluded from both the display and the QIEC evaluation. Any PD event falling within one of these rectangles will be ignored. To draw a rectangle, click and drag the mouse across the desired area of the screen. A frame will be drawn around the selected position as you drag the mouse. After releasing the mouse button, the rectangle will be shown in grey, indicating the gated area. By clicking the right mouse button and dragging the mouse, it is possible to create a phase gate, which extends across the entire height of the screen.

More than one gate can be created in this way. Gates can overlap and can be mixed freely between phase-amplitude and phase gates. To remove a gate, double-click on it (using the left mouse button). You can also remove all gating windows by using the function Clear all gate rectangles from the Advanced menu (see 3.3.5 "The Advanced Menu" on page 33).

Application

5.7.2 PD Detection Settings

The center frequency (fCenter) sets the nominal frequency at which the charge integration takes place. The Bandwidth selects the frequency range around the center frequency. You can select the following bandwidths: 100 kHz, 300 kHz and 1 MHz.

Figure 5-39 PD detection settings

To configure the system for a measurement in compliance with IEC 60270 set, for example, the fCenter slide to 350 kHz. Next, select 300 kHz for the Bandwidth. Uncheck the High Sensitivity Mode option.

It is also possible to conduct RIV measurements. For this purpose, enable the Measure RIV option. RIV expresses PD activity as a voltage that can be picked up using a radio receiver at a certain frequency.

Note: RIV measurements are almost always performed at a center frequency of 1 MHz.

Caution: When in High Sensitivity Mode, the MPD unit is much more susceptible to be damaged by flashovers.

Application

5.7.4 Gamut Settings

Clicking on the Gamut button brings up the window shown in Figure 5-41, which allows to modify the way that colors are assigned to the various histogram classes. Each point in the histogram counts the number of PD events with a certain charge level at a certain phase position and gets assigned a color according to the gamut settings.

Figure 5-41 Gamut settings

The gamut consists of a number of classes which each have a color, and which corresponds to a specific number of PD events per second (a.k.a. PD rate). As the histogram is built, a point gets assigned the color of the highest gamut class whose PD rate is lower than the histogram point’s PD rate. The gamut can be set to automatically compute class boundaries for all classes in a logarithmic or linear fashion, with the top class corresponding to the maximum value for the histogram. For this purpose, select Auto-compute in the Classification Boundaries box, and select either Linear or Logarithmic.

By selecting the Auto-assign maximum setting, the gamut can also be set to track the maximum PD rate in the histogram and adjust the class boundaries accordingly.

Enabling the Apply Dithering setting causes the histogram points to become approximately 16 times "bigger" (that is, PD events are counted not only by the histogram point to which they belong, but to a lesser extent also by neighboring points). This causes the histogram to form a significant pattern more quickly, but will produce a "fuzzier" pattern.

Anchor to measure time adjusts the class coloring such that the proper coloring is only reached at the end of histogram acquisition (that is, at the end of the measure time). As the histogram is built, the coloring will become progressively more red (if red is the top class’ color). To select every class boundary manually, select Set Manually in the Classification Boundaries box. Subsequently, you can enter the value for each color class.
