3. P126 & P127 FURTHER TESTS
3.1 Introduction
The following procedures are written for demonstrating the main protection functions of the
MiCOM P126 (where possible) & P127 relays using an Omicron test or similar. The tests do
not test the limits / boundaries of all available function characteristics. They do tests that the
function is operating at one or two chosen points an a characteristic. This document is not a
complete commissioning procedure but could be referred to when performing commissioning
tests in association with the commissioning section of the service manual.
The procedures will state if a deviation from the standard connections or default settings is
required for testing a particular function. For specific on site applications only enabled
functions would be tested using application specific settings.
3.2 Test equipment
The test procedure has been written on the assumption that an Omicron, or equivalent, test
set will be used. Auxiliary supplies of adequate rating will also be required.
3.3 Type used relay
The following tests have been done using a P127 with the following characteristic.
•
Earth Current : 0.01 to 8Ien
•
Voltage input : 57-130V
•
Auxiliary supply voltage : 130-250Vdc/110-250Vac
•
Communication protocol : Mod Bus
•
HMI Language : English
•
Relay software : Current Version
3.4 Test configuration
Input the factory default settings. These settings shall then be downloaded and recorded in
the test results. Any changes to the settings required by this test procedure shall be recorded
in the test results. Any deviation from the default settings will be indicated for each test.
3.5 Connections to test equipment
The test equipment will be wired as described in the table below unless otherwise stated.
3.6 Test Overcurrent Protection
The following general settings for the relay are suggested
•
VT Connection : 3Vpn
•
Line CT primary : 1A
•
Line CT secondary : 1A
•
E/Gnd CT primary : 1A
•
E/Gnd CT secondary : 1A
•
Line VT primary : 0.10 kV
