3 Phase Prospective Fault Current Tests - PFC Live testing for prospective earth fault current PEFC and prospective short circuit current PSCC (PFC tests). These tests are demonstrated on a live 3 phase distribution board and will help with AM2 and AM2S exams. We use the rule of thumb for calculating the PSCC test by taking the highest reading form the line and neutral tests and doubling it and then we go on to show you how some instruments can measure PSCC between line conductors. As always pre

Prospective Fault Current PSCC, PEFC, PFC and External Earth Fault Loop Impedance Ze - Live Tests In this video Marcus carries out using the 2 lead high setting on his Megger MFT tester the external earth fault loop impedance (Ze) and prospective fault current tests. These live tests are carried out from inside the consumer unit (fuse board or fuse box) and will confirm the incoming supply has a connection to Earth and that the overcurrent protective devices can withstand the possible high level

Measuring Prospective Fault Current (PFC) at the Origin of a Single Phase Supply (Live Test) Student training aid for the live test measuring prospective fault current PFC using a MFT Megger tester. Includes a full demonstration of how to measure PFC current. This test is shown being done under controlled condition in a college workshop. I measure both prospective short circuit current PSCC and prospective earth fault current PEFC and record the highest of the 2 readings. Videos are training aid
