11 TESTING AND COMMISSIONING
11.1 Commissioning Tests & Equipments Required
The following tests help you to configure the settings in ADR233B and verify whether the relay is
properly working or not.
The tests are conducted to ensure whether the relay settings and logics are correct or not. The
procedure can be modified as necessary to confirm to standard practices. For initial relay
installation this procedure can be used but you can configure the relay according to the required
application.
Install and connect ADR233B Relay according to your protection design.
Following instruments are used for testing the relay:
• Digital Multi Meter True RMS.
• Timer with precision of 1ms resolution.
• Auxiliary AC/DC Supply.
• 3 phase 440 V source with sufficient capacity for through fault stability check.
• Test & shorting leads with sufficient capacity.
• Tong testers/ clamp meter to measure current at switchyard (1-300A) & at relay terminal
(1mA- 10A).
• For Calibration and Measurement customer can use numerical test kits like F6150 or
CMC356 or MPRT or equivalent
Three-phase voltage and current injector with phase angle control
• PC having USB port with serial communications cable with following software (minimum
configuration):
The IEC 60870-5-103 communication can be verified by using the ASHIDA Relay Talk-
V2 software.
The ASHIDA Relay Assist Software (Electrical Parameter Calculator) is used as
commissioning support.
11.2 Checking of External Circuitry
Connection Tests
Step 1: Remove control voltage and AC signals from ADR233B 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.
