Pole Drilling

Step 1Drill two -inch (17-mm) diameter holes in

the front of the utility pole at the desired heightfor mounting the switch. See Figure 2. Refer tothe ED drawing. The centerline- to- centerlinedistance of the holes must be 14 inches (356mm).

Inserting Pole MountingHardware

Step 2Insert two -inch diameter through-bolts (notfurnished) in the holes drilled in Step 1. Securethese bolts loosely with necessary washers

and nuts in such a manner that the heads ofthe bolts project sufciently, approximately3 inches (76 mm), from the face of the poleto engage the switch mounting bracket. SeeFigure 2.

Note: When mounting the switch to a wood pole, it is recommended tha t suitable sizedsquare washers be placed under the nutsagainst the wood pole. The use of spring-typewashers between the square washers andnuts is also recommended to compensate forwood-pole shrinkage and thus maintain fas-tener tightness.

Switch InstallationStep 3

CAUTIONDo not lift the switch by rigging on thelive parts or pole-unit bases, nor subjectthese parts to undue stress from slings orfall lines. Misalignment of the contactsand the interrupters may result from suchhandling.

Handle and lift the switch as described in theHandling section of this instruction sheet.When the switch is hoisted to its mountinglevel, guide the assembly so that the through -bolts projecting from the utility pole slip intothe holes in the switch mounting bracket.(The bracket is provided with a keyhole and

Step 8The Omni-Rupter terminal pads are silver

plated and do not require abrasive cleaningas a part of their preparation. Wipe any dirt

or grease from the surface, and apply a thickcoating of Penetrox A or other appropriateconductor preparation compound. DO NOTwire-brush the terminal pads. Wire brushingmay scratch the plating.

Step 9

WARNINGUse care not to apply excessive load tothe terminal pads during installation of the

jumper connector. Jumper connector mustbe in-line with and level to the terminal pad

bolt holes before securing jumper fasten-ers to the terminal pad. Failure to attach

jumpers properly can result in switchdamage, causing improper operationor arcing.

When high-voltage conductors are to beconnected using aluminum-alloy connectors ,the following procedures should beemployed:

a. Thoroughly wire-brush the current- transfersurfaces of each connector and immedi-ately apply a liberal coating of Penetrox

A (available from Burndy Corporation) oranother appropriate conductor preparationcompound to the brushed surfaces.

b. Prepare the conductors using established procedures and clamp them in their respec-tive connectors.

For other types of connector, follow themanufacturers recommended preparation

procedure before connecting to Omni -Rupterterminal pads.

OPERATION

Switch Energization

WARNING

Before energization and at all times whenenergized, the Automated Omni-RupterSwitch base and control unit enclosuremust be connected to a suitable earthground at the base of the pole and bondedto the system neutral, if present, in accor-dance with this instruction sheet. Proper

precautions must be taken to ensure thatthe local earth ground cannot be severedor removed. Failure to observe theseinstructions can result in serious per-sonal injury or death.

WARNINGThe stored-energy operator and theswitch contain fast-moving parts that canseverely injure fingers. Do not removeor disassemble operator unless directed byS&C Electric Company.

Step 23 Af ter maki ng all user connections to thecontrol unit in accordance with the S&Cinstruction sheet covering the applicablecontrol unit, energize the Omni-Rupter

Automated Switching Sys tem according tostandard operating practices. Conrm that theappropriate power and selector switches are inthe proper positions and that the appropriateLEDs are illuminated, as discussed in theinstruction sheet furnished with the controlunit.

DANGER Automated Omni-Rupter Switches may beenergized from either side and with bladesin any position. Before inspecting, servic-ing, or repairing this switch or working onthe conductors on either side of the switch,test for voltage using proper high-volt-age test equipment. Then install suitablegrounding equipment. Failure to observethese precautions can result in seriouspersonal injury or death.

Emergency Manual Operation

Step 26In the event of electrical power loss, a standard

or extendible hookstick can be used to openand close the switch. If the spring is fullydischarged, pull on the pull-ring seven to ninetimes to effect a change of state. If the springhas been previously charged, just a single pullis required. Refer to Figure 27.

Operate the pull-ring until the switch iseither fully open or fully closed. DO NOT

par tially charge the opera tor (between oneand seven times).

WARNING

When operating manually, DO NOT leave the stored-energy operator partiallycharged. Ensure that the operator is ineither the fully charged or fully discharged

position. A partially charged operatormay unexpectedly change state whencontrol power is applied.

4 Switches must be applied on effectively grounded systems at line-to-line voltages between 14.4 through 17.0 for 14.4-kV switches, and between25 through 29 for 25-kV switches.

5 Automated Omni-Rupter switches rated 14.4 kV and 25 kV can carry upto 1000 amperes on a continuous basis for ambient temperatures to 40Cwith a minimum wind velocity of two feet per second. Emergency inter-rupting performance may be expected for currents to 1000 amperes.

6 The 1-second rating is 25,000 amperes RMS symmetrical and the 3-sec-ond rating is 16,000 amperes RMS symmetrical.

7 The two-time duty-cycle fault-closing rating for an automated Omni-Rupter switch is 20,000 amperes RMS symmetrical. The three-time

duty-cycle fault-closing rating for these switches is 15,000 amperes RMSasymmetrical. The duty-cycle fault-closing rating denes the ability toclose the switch the specied number of times against a three-phase faultwith symmetrical current equal to the listed value, with the switch remain-ing operable and able to carry and interrupt rated continuous current.

8 Catalog numbers shown include switch with stored-energy Omni-Mateoperator. A control unit (including 35-foot shielded control cable), sensors,and hinge side sensor mountings must be specied separately.

9 Leakage distance is 14 inches for 14.4 kV and 24 inches for 25 kV.

0 These switches include dead-ending brackets as standard. When dead-ending to these brackets, extension-link assemblies are required. Exten-sion-link assemblies can be provided by adding sufx -D to the catalognumber of the switch. Maximum dead-end loading: 2000 pounds per con-ductor where pull-off forces are applied to only one side of the switch;

8000 points per conductor where equal pull-off forces are applied to bothsides of the switch except switches with extra mounting pole clearancefor which dead-end loading is limited to 1500 pounds per conductor where

pull-off forces are applied to only one side of the switch).

The loading from the jumpers shall not exceed 90 lbs. in line and 30 lbs. perpendicular to the terminal padper IEEE Standard ANSI C37.321996Section 8.8.2.2.

Ice shields are included with all switches in the tired-outboard mount-ing conguration to ensure -inch ice-breaking capability. Ice shields arenot required for switches in upright-mounting congurations.
