How to fix no output current from Megger Test Equipment Sverker?
If there's no output current from your Sverker, here's what you should check: * Make sure the power cord is properly plugged in. * Check miniature circuit breakers F1 and F2, as they may have tripped. * The thermal cut-out may have tripped due to an overload. This resets automatically after some time.
What to do if Megger Test Equipment displays abnormal current readings?
If you are seeing abnormal current readings on your Megger Test Equipment, it's likely that the current is being measured at the wrong test point. Ensure that you have selected the correct test point for the ammeter.
What does O.F. mean on Megger Programma Sverker 760?
O.F. means overflow and indicates that the range being used has been exceeded. One possible cause is that the measurement cycle proceeded too rapidly to permit the range to be switched automatically. You should repeat the measurement. Since range switching data is stored in a memory, your second try may very well be successful.
What to do if no current reading appears on Megger Programma Sverker 760 Test Equipment?
If no current reading appears when measurements are made via the ammeter’s panel input, the miniature circuit breaker F4 may have tripped because the measured current exceeded 6 A. Check the miniature circuit breaker.
How to fix no voltage reading on Megger Programma Sverker 760 Test Equipment?
If no voltage reading appears, the voltmeter panel input is not connected. Connect the voltmeter input.
Why is there no phase-angle reading or jumping values on my Megger Test Equipment?
If you're getting no phase-angle reading or jumping values, it means no current is being generated. Both current and voltage must be generated. Press 'ON' to generate the current.
Why are operating times unexpectedly short on Megger Programma Sverker 760 Test Equipment?
If you are seeing unexpectedly short operating times, it's because contact bounces are occurring in the protective relay equipment. To resolve this, connect the Sverker capacitor in parallel with the test object.
What causes make/break contact malfunctions in Megger Test Equipment?
If the make/break contact malfunctions, the miniature circuit breaker F3 may have tripped. 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, the 'delay off' function is activated (time that elapses after tripping before generation is stopped) and start and stop pulses are issued during the 'delay off' period. Shorten the 'delay off' period or set it to 0.
What causes the separate AC voltage source to malfunction on Megger Programma Sverker 760?
The PTC resistor that serves as a thermal cut-out may have tripped because of an overload. Wait. This cut-out is reset automatically after a certain amount of time has elapsed.
