Metering Transducer Module; Hi-Pot Testing - GE Multilin 565 Instruction Manual

INSTALLATION

Metering Transducer Module

The Metering Transducer Module is an optional unit which
gives the 565/575 additional functionality. The mounting ar-
rangement is shown in Figure 2.9 and the typical wiring for
PT's and CT's is shown in Figure 2.7A and Figure 2.7B.
Additional analog outputs can be wired as shown in Figure
2.8A and Figure 2.8B.

Hi-Pot Testing

The Relay has been tested at the factory for 1 second at
1800 VAC in order to verify its dielectric strength. Hi-pot
testing to verify the wiring into the gear must be done with the
inner relay cradle removed from the outer case. JMP1 must
be removed before Hi-pot testing. This jumper can be located
by viewing Figure 2.4.
Hi-pot testing should only be performed on the terminals
mentioned in the enclosed table of this addendum. With
these points in mind, here are the necessary steps for Hi-
potting a 565/575 Relay when wired into the gear.
2-6
1. Remove the 565/575 Relay inner chassis from the outer
case. Failure to remove the relay from the outer case can
cause failure of the relay.
2. Remove jumper JMP1 from the outer case's rear
motherboard. Please see Figure 2.4 for this jumper's
location.
3. Hi-pot the following terminals with respect to surge ground
for 1 second at 1800 VAC:
4. Ensure that jumper JMP1 is properly inserted after Hi-pot.
This should be on the two right most pins of the group of
three pins. If not, the unit will not be properly grounded.
5. Install the relay's inner chassis into the outer case.
