ETL-35

SUBSTATION EQUIPMENT TEST VAN

ETL-35 is a van-mounted 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 substation objects with small electrical capacitance with AC voltage of up to 100 kV and measuring dielectric dissipation factor (Tan Delta) at industrial frequency.

A microammeter included with the system allows testing surge arresters with DC (rectified) voltage up to 60 kV and measuring the leakage current with up to 0.01 mA significance.

DIELECTRIC DISSIPATION FACTOR MEASUREMENT

ETL-35 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 voltage of industrial frequency.

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