Checking the operation of MAINFUF and PILOTFUF
1. Simulate normal operation conditions with three-phase voltage on the main fuse group and the
pilot fuse group. Ensure the values are equal to their rated values.
2. Decrease one of the three-phase voltages on main fuse group or pilot fuse group. The voltage
change must be greater than the set value for Ud>MainBlock or Ud>PilotAlarm. MAINFUF or
PILOTFUF signals are activated without any time delay.
3. Set normal conditions as mentioned in step 1. MAINFUF or PILOTFUF signals should reset.
4. Set SealIn to On, UD>MainBlock to 20% of UBase and USealIn to 70% of UBase.
5. Apply three-phase voltages with the value slightly below USealIn level.
6. Decrease one of the three-phase voltages on main fuse group. The voltage change must be
greater than the set value for Ud>MainBlock. MAINFUF signal is activated.
7. After more than 5 seconds increase the measured voltage back to the value slightly below
USealIn level. MAINFUF signal should not reset.
8. Slowly increase measured voltage to the value slightly above USealIn until MAINFUF signal
resets.
9. Record the measured voltage and compare with the set value USealIn.

Completing the test

Continue to test another function or end the test by changing the TESTMODE setting to Off. Restore
connections and settings to the original values, if changed for testing purposes.

Voltage based delta supervision DELVSPVC

Prepare the IED for verification of settings outlined in Section
11.9.4.1

Verifying the signals and settings

Make sure that the function is connected to SMAI function with U3P signal.
Delta supervision function has 6 different modes of operation. Proceed as follows to test the function
in a particular mode.
1. Set the following parameters:
•
•
•
•
•
•
•
2. Set the constant voltage input of UL1 = 63.5V at 0° and UL2 = 63.5V at 120° and UL3 at 63.5
-120° secondary at rated frequency.
3. Based on the mode of operation, carry out the following changes on input condition of Step
detect start condition.
Each mode is given for increase and decrease operation. (3-a and 3-b)
