Question ( worth 15 Marks )
Describe how a test for earth fault loop impedance, by direct measurement may be carried out on a circuit supplying a three-phase steamer . My answer would be I would not measure Zs on this circuit as it would contravene EAW Safe working practices. The value for Zs can be achieved without working near live conductors by R1+R2+Ze. Comments :- I guess my answer would not get me 15 marks ! Can Anyone out there give me a Model answer to the question ? i.e. What are the examiners looking for ? Thanks |

The clue is in "direct measurement" so it is a live test!
1 seek permission 1a signs/barriers 2 correct instrument and scale 3 calibration condition and operation 4 leads to GS 38 5 test between L1 - E 6 test L2 -E 7 Test L3 -E 8 record highest reading 9 reinstate circuit 10 compare readings to OSG or BS7671 corrected to 80% No one really knows but that's a fair place to start I reckon. regards Marc |
