6.6 Conjunctive Tests
6.6.1 On Load Test
With the relay connected to the line which is carrying a load current, it is possible to check the
polarity of the voltage transformer and current transformer and the phase rotation with the
metering displays on the LCD screen.
Open the following "Metering" screen from the "Status" sub-menu.

Note:
The magnitude of voltage and current can be set in values on the primary side or on the
secondary side by the setting. (The default setting is the primary side.)
Phase angles are expressed taking that of the voltage input as the reference angle.
Check that the phase rotation is correct.
Verify the phase relation between voltage and current with a known load current direction.
6.6.2 Tripping Circuit Test
The tripping circuit including the circuit breaker is checked by forcibly operating the output relay
and monitoring the breaker that is tripped. Forcible operation of the output relay is performed on
the "Binary output" screen of the "Test" sub-menu as described in Section 6.4.3.
Tripping circuit
Set the breaker to be closed.
Press 2 (= Binary output) on the "Test" sub-menu screen to display the "Binary output"
screen. The LCD displays the output modules mounted.
Enter 1 to select the IO1 module, then the LCD displays the screen shown below.
