5.3.3 Reclosing

This unit can perform reclosing test .

There are two states for setting. You can set amplitude and phase for these two
states.

During test, you must connect the relay’s acting contacts and reclosing contacts
to the binary input terminals of the tester to make sure the correct logic for
output.

Time counting definition: pick up, denotes the time of first time tripping; reclosing,
denotes the time between binary input a and b after each fault;acctrip, denotes
the time of second time tripping.
Test process
1) Select test item, go into the reclosing unit..
2) Set voltage and current values of the two states.
3) Test:
Press the Run button, the tester will start to output under the Constant Fault . Press the
ENTER button into the “Test” and start time counting at the same time. As soon as the
tester receives the binary input of relay acting signal, it will record the acting time
