Completing The Test; Thermal Overload Protection, One Time Constant Lpttr (26) - ABB Relion 650 Series Commissioning Manual

1MRK 511 248-UUS A
1. Measure that the operate current is equal to the
The function activates the BFI_3P and STDIRIN output.
2. Measure the operate time of the timer by injecting a current to get two times the set
INNonDirPU operate value.
3. Compare the result with the expected value.
The expected value depends on whether definite time
selected.
4. Continue to test another function or complete the test by setting the test mode to
Residual overvoltage release and protection
Procedure
1. Measure that the operate voltage is equal to the
The function activates the BFI_3P and STUN signals.
2. Measure the operate time by injecting a voltage 1.2 timers set
3. Compare the result with the set
4. Inject a voltage 0.8 ·
at the chosen angle.
5. Increase the voltage until the directional function is released.
6. Compare the measured value with the set

Completing the test

Continue to test another function or end the testing by setting the parameter
Disabled under Main menu/Tests/IED test mode/1:TESTMODE. If another function is tested, then
set the parameter
SDEPSDE(67N,IN<->)/1:SDEPSDE for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter

Thermal overload protection, one time constant LPTTR (26)

Prepare the IED for verification of settings as outlined in
Values of the logical signals for LPTTR (26) are available on the local HMI under Main menu/Tests/
Function status/Current/LPTTR(26,T>)/1:LPTTR. The Signal Monitoring in PCM600 shows the
same signals that are available on the local HMI.
Check that the input logical signal BLOCK is logical zero and that on the local HMI, the logical
signal TRIP, PICKUP and ALARM are equal to logical zero.
7.3.6.1 Completing the test
Continue to test another function or end the testing by setting the parameter
Disabled under Main menu/Tests/IED test mode/1:TESTMODE. If another function is tested, then
set the parameter
LPTTR(26,T>)/1:LPTTR for the function, or for each individual function in a chain, to be tested
next. Remember to set the parameter
