Hi everyone,
My resit on my AM2 live testing is monday coming and I need some help/ gudiance on anyone who has sat theres to help me.
Confim polarity by measuring the voltage between each phase to N and each phase to earth, then phase to phase to ensure I am getting 230/400V etc.
So then, Ze test disconnect main earth and test each phase ( 3phases) to earth . Highest value record on test sheet as Ze. Then reinstate the main earth. Make sure test equipment is set to 2 test lead LOW or NO TRIP.
Zs test at db, same as ze but, the main earth is connected. Again test each phase to earth. Record highest value on the test sheet. Again, test meter on 2 test lead Low or No trip.
Then, PFC testing, set the test equipment to 2 test lead high I think it is... then measure PEFC so each phase to earth so L1- E, L2- E and L3-E. Mental note of this value.
Then same test again but PSCC so measuring each phase to neutral. So, L1-N , L2- N, L3-N. Mental note of this value.
The test equipment I am using cant measure phase to phase so. Simply take highest value and double it normally PSCC value.
Record this on test sheet as IpF.
Then cover back on db. Then the board can be fully energised/ lock off taken off. Then carry out RCD tripping times on the ring at the FURTHEST point. Record tripping times on test sheet and functional testing of the test button. Then, functional testing of all other circuits to confirm that they are working as they should be etc.
Then phase rotation ensure I am getting correct phases at the commando outlet point and the motor circuit.
Does that all sound right? If not let me know please as my resit is Monday morning!
Cheers!
