Test Ethernet Communication - GE MiCOM P40 Agile Technical Manual

Chapter 25 - Commissioning Instructions
The only checks that need to be made are as follows:
1. Set the RP2 Port Config cell in the COMMUNICATIONS column to the required physical protocol; (K-Bus,
EIA(RS)485, or EIA(RS)232.
2. Set the IED's Courier address to the correct value (it must be between 1 and 254).

TEST ETHERNET COMMUNICATION

For products that employ Ethernet communications, we recommend that testing be limited to a visual check that
the correct ports are fitted and that there is no sign of physical damage.
If there is no board fitted or the board is faulty, a NIC link alarm will be raised (providing this option has been set in
the NIC Link Report cell in the COMMUNICATIONS column).
5.3 SECONDARY INJECTION TESTS
Secondary injection testing is carried out to verify the integrity of the VT and CT readings. All devices leave the
factory set for operation at a system frequency of 50 Hz. If operation at 60 Hz is required, you must set this in the
Frequency cell in the SYSTEM DATA column.
The PMU must be installed and connected to a 1pps fibre optic synchronising signal and a demodulated IRIG-B
signal, provided by a device such as a P594 or a REASON RT430.
Connect the current and voltage outputs of the test set to the appropriate terminals of the first voltage and current
channel and apply nominal voltage and current with the current lagging the voltage by 90 degrees.
5.3.1 TEST CURRENT INPUTS
This test verifies that the current measurement inputs are configured correctly.
1. Using secondary injection test equipment such as an Omicron, apply and measure nominal rated current to
each CT in turn.
2. Check its magnitude using a multi-meter or test set readout. Check this value against the value displayed
on the HMI panel (usually in MEASUREMENTS 1 column).
3. Record the displayed value. The measured current values will either be in primary or secondary Amperes. If
the Local Values cell in the MEASURE'T SETUP column is set to Primary, the values displayed should be
equal to the applied current multiplied by the corresponding current transformer ratio (set in the CT AND VT
RATIOS column). If the Local Values cell is set to Secondary, the value displayed should be equal to the
applied current.
Note:
If a PC connected to the IED using the rear communications port is being used to display the measured current, the process
will be similar. However, the setting of the Remote Values cell in the MEASURE'T SETUP column will determine whether the
displayed values are in primary or secondary Amperes.
The measurement accuracy of the IED is +/- 1%. However, an additional allowance must be made for the accuracy
of the test equipment being used.
