Feeder Protection Relay
Technical Reference Manual
The first value shows the average current of all three phases measured during one
minute. The value is updated once a minute.
The second value shows the average current during an adjustable time range,
ranging from 0 to 999 minutes, with an accuracy of one minute. This value is
updated at the expiration of each time range.
The third value shows the highest one-minute average current value measured
during the previous time range. However, if the time range is set to zero, only the
one-minute and the maximum demand value is shown. The maximum value is the
highest one-minute mean value since the last reset.
The demand values can be set to zero through serial communication using SPA
parameter V102. The average values are also reset if SPA parameter V105 is
changed or the relay is reset.

Commissioning tests

The following two product functions can be used during the commissioning of the
relay: function test and digital input test.
The function test is used for testing the configuration as well as the connections
from the relay. By selecting this test, the internal signals from the protection stages,
the motor start-up signal, the external trip signal and the IRF function can be
activated one by one. Provided that the signals have been set to be routed to the
output contacts (PO1...PO3 and SO1...SO5) with the switches of SGR1...SGR8, the
output contacts are activated and their corresponding event codes are generated
when the test is run. However, activation of the internal signals from the protection
stages, the signals from the auto-reclose function, the external trip signal and the
IRF function do not generate an event code.
The digital input test is used for testing the connections to the relay. The state of the
digital inputs can be monitored via the HMI.
Refer to the Operator's Manual for instructions on how to perform the tests.

Disturbance recorder

Function

The relay features an integrated disturbance recorder which continuously captures
the curve forms of the currents as well as the status of both internal signals and
digital input signals and stores these in the memory.
Triggering of the recorder generates an event code. After the recorder has been
triggered, it continues to record data for a pre-defined post-triggering time. An
asterisk is shown on the LCD on completion of the recording. The status of the
recording can also be viewed using SPA parameter V246.
