1.6 Types of Leakage Current Measurement
20
A protective conductor current measurement measures the electric current that flows through a protective
earth conductor (grounding wire) during normal operating conditions.
Like Earth leakage current, class II equipment does not have a protective earth wire and therefore does
not require measurement of protective conductor current.
To measure the protective conductor current, place a resistor with a resistance so small as to be negligi-
ble in the protective earth wire circuit.
