IEC 62368-1 Clause 5.4.11 Non - Inductive Resister 5k Ω For Current Leakage
Product Information:
This non-inductive resistor, category: wire-wound resistors. It is required by IEC 62368-1:2018 clause 5.4.11 and Annex H, IEC 60950-1 clause 2.4.2, IEC 60065-1:2014 clause 7. Used to test the leakage current between primary and secondary.
Test Procedures and Operation
Please refer to the relevant standards.
Take IEC 60335-1 clause 8 as an example:
Voltages and currents are measured between the relevant parts and each pole of the supply source. Discharges are measured immediately after the interruption of the supply. The quantity of electricity in the discharge is measured using a resistor having a nominal non-inductive resistance.
NOTE 1 Details of a suitable circuit for measuring the current are given in figure 4 of IEC 60990.
NOTE 2 The quantity of electricity is calculated from the sum of all areas recorded on the voltage/time graph without taking voltage polarity into account.
