Why is the AC Voltage Source LED blinking on my Megger SVERKER 780 Test Equipment?
If the AC Voltage Source LED on your Megger Test Equipment is blinking, it could be due to undervoltage or overvoltage on the input, overcurrent on the output, or the main frequency being outside the range of 40 to 80 Hz. To resolve this, press the I/O button (44) to disable the output.
What to do if Megger SVERKER 780 shows unexpectedly short operating times?
If your Megger Test Equipment shows unexpectedly short operating times, this may be due to contact bounces occurring in the protective relay equipment. To solve this, connect the SVERKER capacitor in parallel with the test object.
How to troubleshoot no output current from Megger SVERKER Test Equipment?
If no output current is coming from your Megger SVERKER Test Equipment, several issues could be the cause. First, ensure the power cord is properly plugged in to address a lack of mains voltage. Second, check miniature circuit breakers F1 and F2, as they may have tripped. Finally, the thermal cut-out might have tripped due to an overload; this will reset automatically after some time.
Why are abnormal current readings displayed on Megger SVERKER 780 Test Equipment?
If abnormal current readings are displayed on your Megger Test Equipment, it's likely that the current is being measured at the wrong location (test point). Verify that the correct test point has been selected for the ammeter.
What to do if no current reading appears on Megger SVERKER 780 ammeter’s panel input?
If no current reading appears when measurements are made via the ammeter’s panel input on your Megger Test Equipment, the miniature circuit breaker F4 may have tripped because the measured current exceeded 6 A. Check the miniature circuit breaker.
Why does Megger Test Equipment show fewer reclosings than desired?
If fewer than the desired number of times appear in the time table after measuring reclosings on your Megger Test Equipment, the ”delay off” function may be activated, and start and stop pulses are being issued during the ”delay off” period. Shorten the ”delay off” period or set it to 0.
Why does my Megger Test Equipment show no voltage reading?
If no voltage reading appears on your Megger Test Equipment, the voltmeter panel input is likely not connected. Connect the voltmeter input.
What does 'O.F.' mean on my Megger SVERKER 780 Test Equipment?
If your Megger Test Equipment displays 'O.F.', it means that the measurement cycle proceeded too rapidly to permit the range to be switched automatically. Repeat the measurement. Since range switching data is stored in memory, your second attempt may be successful.
Why does Megger Test Equipment have no phase-angle reading?
If your Megger Test Equipment shows no phase-angle reading (or jumping values), it indicates that no current is being generated. Both current and voltage must be generated. Press "ON" to generate the current.
What causes the separate AC voltage source to malfunction on Megger Test Equipment?
If the separate AC voltage source on your Megger Test Equipment malfunctions, the PTC resistor that serves as a thermal cut-out may have tripped due to an overload. Wait. This cut-out is reset automatically after a certain amount of time has elapsed.
