•
The Trip Coil contact connection should be the same as the schematic diagram.
•
Latching type annunciation contact connection as per requirement of site.
2.1.9.1
Earthing
An earthing terminal is provided at the back of the relay. Ensure that the case earthing connections
are used to connect the IED to a local earth bar using an adequate conductor.
When several relays are present, make sure that the copper earth bar is properly installed for solidity
connecting to the earthing terminal of each relay.
2.1.9.2
CT Polarity
Ensure proper CTs are connected as per required maximum load current and their polarity. When all
CTs are connected with proper polarity, unbalance current flowing through earth fault element will be
approximately zero. Otherwise the relay will trip on earth fault when the CB is energized.
2.1.10
Check Relay Settings
The relay setting check ensures that all the application-specific settings for that installation have been
correctly applied to the relay. Enter all settings manually via the front panel interface or using the P50
Agile configurator tool.
2.1.11
Protection Timing Checks
Only one protection function needs to be checked. This is to verify the timing on the processor is
functioning correctly.
2.1.11.1
Overcurrent Check
If the overcurrent protection function is being used, test the overcurrent protection for stage 1.
1.
Check for any possible dependency conditions and simulate as appropriate.
2.
In the
CONFIGURATION
menu, disable all protection elements other than the one being
tested.
3.
Make a note of which elements need to be re-enabled after testing.
4.
Connect the test circuit
5.
Perform the test
6.
Check the operating time
2.1.11.2
Connecting the Test Circuit
1.
Identify the function associated with the overcurrent protection stage 1 trip.
2.
Use the output relay RL1 for assigning the overcurrent trip function
3.
Use the IO Masking function in the P50 Configurator or the IO configuration menu on the relay
HMI to map the protection stage under test directly to an output relay.
4.
Connect the output relay so that its operation will trip the test set and stop the timer.
5.
Connect the current output of the test set to the A-phase current transformer input.
6.
Ensure the timer starts when the current is applied.
