1. GENERAL
2. INSTALLATION AND OPERATION
The SE-100T is a ground-fault-relay tester for 5-A and
15-A resistance-grounded systems. The SE-100T has an
output ammeter, a test pushbutton, low (LO) and high
(HI) outputs, and a remote-test input (RMT). Test
currents of 0.65 A (LO) or 2.75 A (HI) are provided for
injection in window-type current sensors. Multiple CT
wraps can provide a window current that is a multiple of
the ammeter reading.
SE-100T outline and mounting details are shown in
Fig. 1. Typical connections are shown in Fig. 2.
Connect supply voltage to L1 and L2. Connect chassis
bonding terminal
to ground. Loop a test wire through
the windows of the ground-fault CT's. Connect one end
of the test wire to terminal C and the other end to terminal
LO or terminal HI for a test current of 0.65 or 2.75 A.
For remote operation, connect a normally open contact
between terminals L1 and RMT. To test ground-faultrelay operation, press the test pushbutton for an interval
that is longer than the time-delay setting of the relay or
relays being tested. If precise current adjustment or a
timed output is required, use the SE-400 ground-faultrelay test unit.
