The panel testing in factory, commissioning or during maintenance programs goes through many quality, inspection and test procedures regarding the electrical operation, which usually cover wiring and polarity continuity, dielectric resistance, functional testing of the protective scheme, relay testing, breakers testing, and other operationalInspection, Test and Measurement Procedures for LV and MV (up to 36kV) Switchgears (on photo Eaton Cutler Hammer Magnum DS Switchgear Inspection, and Transformer Testing) For MV switchgear similar considerations apply although more extensive checks on protective devices, circuit breaker oil, vacuum bottle contact distances are required as low voltage panel testing procedure

Power Frequency Voltage Test. Connect the HV lead from step up transformer to Rphase; Short the Y& B phase and connect to earth. Also connect the enclosure to earth. Switch on the test kit control unit and apply the recommended test voltage (by increasing gradually) for 1 minute to R phase with respect to other phases earthed and grounded
