When doing a Global IR test of an installation, you obtain a reading of 4Mega-ohm. What would you do next:
Nothing, This is above 1MΩ and therefore acceptable
Record the result to be checked again in the near future
Breakdown the installation and retest individually circuit by circuit
Breakdown the installation and test in smaller grouped circuits.
The first three tests in sequence of testing are:
Safe Isolation
Continuity of CPC
Ring Main Final Testing
Polarity
Insulation Resistance
The Maximum permitted Ze value for a TN-S earthing arrangement is:
200
0.8
0.35
0.55
The maximum permitted Ze for a TT earthing system is:
200
0.8
0.35
0.55
The correct calculation for IR is:
RT = R1 + R2 + R3 ...
RT = 1/R1 + 1/R2 + 1/R3 ...
1/RT = 1/R1 + 1/R2 + 1/R3 ...
1/RT = 1/R1 - 1/R2 - 1/R3
