Acceptance testing includes:

Electrical checks on switching ON and OFF

Measuring the contact resistance values in the primary
circuit.

Withstand voltage testing of the primary circuit.

Discharge measurement.

Checking the proper operation of the overcurrent
indicators.

Operation of the position indicators, if installed.

Checking the proper operation of the mechanical
interlocks.

Checking the switch caps for proper operation.



Measurements of voltage losses on the busbar
connections fitted on site.

Applying power to the installation in accordance with
IEC standard 62271-201.

Checking mechanical interlocks and satisfactory
