1.3 DC VOLTAGE RELAY TESTING
1.3.1. Introduction
DC voltage relays usually have an undervoltage threshold
only. We perform the test using the main DC voltage output,
because the auxiliary DC voltage is continuously generated,
and cannot be used for trip timing tests. The following is the
connection schematic.
1.3.2. Connection to voltage output
. Power-on T1000 PLUS, acting on switch (2): the internal light
turns on.
. Set the current adjustment knob (6) completely counter-
clockwise.
