    8. INSULATION TESTS  WARNING Ensure that circuits to be tested are not live. Disconnect the instrument from the circuit under test before operating the function switch. To select the insulation resistance range select INSULATION . 8.1.1 The nature of insulation resistance Live conductors are separated from each other and from earth metal by insulation, which has a resistance which is high enough to ensure that the current between conductors and to earth is kept at an acceptably low level.

  • Page 24: Conduction Current

    8.1.3 Conduction Current Since the insulation resistance is not infinite, a small leakage current flows through the insulation between conductors. Since Ohm's Law applies, the leakage current can be calculated from Fig.16 8.1.4 Surface Leakage Current Where insulation is removed, for the connection of conductors and so on, current will flow across the surfaces of the insulation between the bare conductors.

    9. LOOP/ PSC/PFC 9.1 Principles of measurement of fault loop impedance and PFC If an electrical installation is protected by over-current protective devices including circuit breakers or fuses, the earth loop impedance should be measured. In the event of a fault the earth fault loop impedance should be low enough (and the prospective fault current high enough) to allow automatic disconnection of the electrical supply by the circuit protection device within a prescribed time interval.
  • Page 30 - 1000 ms for distribution circuits and circuits over 32A (at 230 / 400V AC) The compliance with the above rules shall be verified by: 1) Measurement of the resistance Ra of the local earth system by Loop tester or Earth tester.
  • Page 31 Ω L - PE 50.0Hz ATT :ON L-PE Fig.23 For this example the max permissible value is 1667 Ω (RCD =30mA and contact voltage limit of 50 V). The instruments reads 12.74 Ω, thus the condition RA ≤ 50/Ia is respected. However, considering that the RCD is essential for protection, it must be tested (Please refer to RCD TESTS section).
  • Page 32 - 5 s for distribution circuits and circuits over 32A (at 230 / 400V AC) The compliance with the above rules shall be verified by: 1) Measurement of the fault loop impedance Zs by Loop tester. 2) Verification of the characteristics and/or the effectiveness of the associated protective device.

    Max value of Zs for this example is 1.44 Ω (MCB 16A, characteristic C), the instrument reads 1.14 Ω (or 202 A on Fault current range) it means that the condition Zs x Ia ≤ Uo is respected. In fact the Zs of 1.14 Ω is less than 1.44 Ω (or the Fault current of 202 A is more than Ia of 160A).
