The purpose of electrical testing and measurement in electrical installations is to determine the technical condition of equipment and networks.

After production and before commissioning of the equipment, tests and measurements are necessary to confirm the equipment parameters with passport or standard values.

During equipment operation, testing and measurement are necessary in order to control changes in parameters in order to make decisions about the possible further safe and trouble-free use of equipment or to plan repairs.

After repair, tests and measurements are carried out to monitor the degree of restoration of serviceability and resource equipment and network.

Electrical tests and measurements of electrical equipment and networks with a rated voltage of up to 10 kV are performed by the personnel of an electrical laboratory using high-voltage equipment with direct and alternating currents.

Equipment tests are carried out both in the stationary laboratory and at the facilities using the automotive laboratory.
