11 TESTING AND COMMISSIONING
11.1 Commissioning Test, Equipment Required
The following connection tests help you to enter settings into the ADR241B and verify that
the relay is properly connected.
Brief functional tests ensure that the relay settings are correct. It is unnecessary to test every
element, timer, and function in these tests. Modify the procedure as necessary to conform to
your standard practices. Use the procedure at initial relay installation; you should not need to
repeat it unless major changes are made to the relay electrical connections.
a. The ADR241B installed and connected according to your protection design.
b. Digital Multi meter True RMS
c. Timer with precision 1ms.
d. Required Auxiliary supply
e. For Calibration and measurement check & Pick up test, time test, logic operation test
use Power system Simulator DOBEL make F6150 or any Protective relay ac test
source:
•
Minimum: single-phase current source with phase angle control
•
Preferred: three-phase current source with phase angle control
f. A PC with serial port, terminal emulation software, and serial communications cable
with the following software (minimum configuration)
•
For IEC 60870-5-103 communication check: Ashida Relay Talk-V2 software.
•
Ashida Relay Assist software (Electrical Parameter Calculator) to verify
Measured value of normal and sequence current.
11.2 Checking of External Circuitry
Connection Tests
Step 1: Remove control ac signals from the ADR241B by opening the appropriate
breaker(s) or removing fuses
Step 2: Isolate the relay contact assigned to be the TRIP output
Step 3: Verify correct ac and dc connections by performing point-to-point continuity
checks on the associated circuits.
Step 4: Apply ac or dc control voltage to the relay. After the relay is energized, the front-
panel green PROTH LED should illuminate.
Step 5: Use the appropriate serial cable (USB to serial Cable or equivalent) to connect a
PC to the relay.
