3.3.1 Automatic Test
The automatic test must be performed with the circuit-breaker open. With certain relays, it may be
impossible to access/run the test if the circuit-breaker is closed.
Various tests are available for each relay, regardless of the functional characteristics.
The trip time settings of the relays during the tests will depend on the settings of the protections.
The PR010/T unit will display the trip time and test result (OK; FAILED).
At the end of the test, the user is asked if he wishes to record a test report, which can then be
downloaded into a PC.
Details of all the tests performed are given in the chapters dedicated to each individual relay,
available from chapter 4.11 onwards.
3.3.2 Manual Test
The manual test must be performed with the circuit-breaker open. With certain relays, it may be
impossible to access/run the test if the circuit-breaker is closed.
The manual test allows you to check the trip time of the relay with the required load condition. In
detail, you can select the current value within the 0.00 to 16.00 In range, the voltage value within
the 0.0 and 1.3 Vn range, the phase shift between -180° and +180° with 0.75° steps (if the relay
allows voltages and phase shifts to be tested) and select one or more of the phases involved in the
test (L1, L2, L3, Ne, Gte, V1, V2, V3). The phases chosen for the test are indicated by the “
”
symbol.
