Deif uni-line Series Installation And Start-Up Instructions page 2

1. Description
This stator earth fault relay type RMC-142D forms part of a complete DEIF series (the
uni-line) of relays for protection and control of generators.
2. Label
The relay is provided with a label with the following data:
Measuring current
corr. to 100% on scale
Supply voltage
Relay coupling
Shown is relay B as a
normally de-energised
relay, relay C as a
normally energised relay
Highest voltage
with latch circuit
in relation to earth.
Note: The relay is provided with a 200 ms power-up relay, ensuring correct
function of the relay on connection of the auxiliary voltage. Normally
energised contacts ("NE") are not activated (contact does not open/close)
until 200 ms after connection of the auxiliary voltage. Likewise, the relay is
provided with a 200 ms power-down circuit, ensuring supervision and
maintenance of any set point exceeding for 200 ms after disconnection of
the auxiliary voltage.
