ETL-250

SUBSTATION EQUIPMENT TEST VAN

ETL-250 is a van-based system designed for testing electrical substation equipment.

Apart from insulation withstand testing with DC (rectified) voltage up to 60 kV and ability to measure very small leakage currents, the system can be used for testing various objects with small electrical capacitance with AC voltage of up to 250 kV and measuring dielectric dissipation factor (Tan Delta) at industrial frequency.

ETL-250 system can be equipped with an optional Tan Delta module for accurate measurement of capacitance and the dielectric dissipation factor at up to 10 kV or up to 250 kV voltage of industrial frequency.

Tan Delta measurement using cable test vans is most often used to assess the transformer insulators on the electrical substations.
