Powered Load and Leakage Test
Cau
tion
The Powered Leakage tests provide four main measurements:-
1 - Power Measurement
This is the power drawn when the EUT is supplied with the nominal
MAINS voltage.
2 – Power Factor
Power factor is often used to ensure that products using motors have
been constructed correctly and that there is no likelihood that moving
parts such as motor bearings have been damages or seated incorrectly.
3 – Earth Leakage (Protective Conductor Current)
Protective conductor current is a measure of the current that is flowing
to earth from the EUT.
4 – Touch Leakage (Touch Current)
Touch Current is a measure of the current that would flow through the
human body if a person was to touch the EUT whilst it is in operation.
The Ground / Earth Bond probe is used to provide a path to Earth via
the internal body model measuring device.
