Vaisala HV MV Equipment rental

Failures in the HV and MV transmission and distribution networks frequently have costly and disruptive consequences. For instance, a recent phase-to-ground fault in the termination of a 380 kV cable at a GIS installation caused so much damage that it was ten months before the cable could be returned to service.

  • Insulation Resistance Tests of High Voltage Equipment

    Jun 19, 2017Also, high voltage equipments are normally designed for a useful insulation life of 20 years and more. Hence proper operation within rated power, temperature and timely maintenance ensure prolonged life of the equipment. In high voltage system, insulation resistance is measured using a 5000 volt DC megger, for voltages upto 6.6 kV.

  • Hi-Pot Test Current, Leakage Current and Insulation

    Oct 31, 2017Myron Boyajian September 2, 2020 . Hi Mr. Nute, I am somewhat confused by the units used in the explanation you offered (copy follows). “Because the insulation resistance and reactance of the stray capacitance is so high, the ac test current can be simplified to the leakage current at 250 V times the ratio of hi-pot test voltage to 250 V.

  • Testing of Capacitor Bank | Electrical4U

    Oct 27, 2020A sensitive capacitance meter is used to measure the capacitance of the bank as whole to ensure the connection of the bank is as per specification. If the measured value is not as calculated, there must be some wrong connection in the bank which to be rectified. For measuring capacitance of a bank, we need not to apply full rated voltage, instead only 10 % of rated voltage to determine the

  • VLF insulation testing - Electrical test equipment

    This equipment negates the need for on-site generation, large step down transformers or generating company supplies to be employed to power the items under test. Because VLF testing supplies a working frequency of 0.1Hz as opposed to the 50/60Hz usually required for live transmission, the physical size of the VLF test set is massively reduced.
