2.2.5 Relay Testing
2.2.5.1 Relay calibration
Before conducting a test, confirm the relay calibration using the following method.
1. Connect P15D relay to current injector and timer.
The following table shows the terminal numbers for CT connections.
Phase Terminal
R B1,B2
Y B3,B4
B B5,B6
N B7,B8
2. Connect the CT terminals using the above table.
3. Adjust rated CT secondary current 1A or 5 A (based on the P15D variant under test). Observe
the current value from the
Measurement menu. The actual current should match the relay
display.

2.2.5.2 Pickup, Trip and Binary Output Test:
1. Connect current source 1A or 5 A (based on the P15D variant under test) to the current input
terminal.
2. Set current setting value to 100% of rated current, TMS at Minimum (x0.02) value.
3. Start current injector to & increase current value till relay pick up and trip. The operating value
should be within 1 to 1.1 times of set pickup value.
4. After tripping of relay, check continuity in between NO and C output contact terminal.
Binary Output Contact Terminal
NO C NC
Latching Type A6 A8 A10
Non Latching Type A5 A7 A9
5. After reducing the current to reset value, only non-latching type relay contact (terminal A5 &
A7) should open.
6. Press RESET Key and latching type contact (terminal A6 & A8) should be open.
2.2.6 Testing of Binary Input Contact:
1. The Binary inputs shall be tested by applying rated voltage to respective binary input
terminals.
