IEC 62368-1 Clause 5.2.2.2 Touch Current Measuring Circuit

Product information:

This test network conforms to the measuring network requirements of IEC 60990 figure 5 touch current and the measurement method of protective conductor current,

(Figure 5- Measuring network, touch current weighted for letgo-immobilization), it is required by IEC 62368-1:2018 clause 5.2.2.2, etc.

An electrical energy source class is determined from both the voltage and the current under normal operating conditions, abnormal operating conditions, and single fault conditions.

Preparation:

Before testing, you need to prepare instruments as follow:

Oscilloscope x1

One or ten times the voltage probe x1

Power supply x1 (the test voltage or frequency that can be adjusted or changed to the required voltage or frequency)
