HV Test Sets for dielectric tests of 110 kV and higher voltage ratings electrical equipment
UIV-(230, 345, 395, 450, 500 кV) Test Sets are designed for dielectric tests with partial discharge measuring of 110 kV and higher voltage ratings in the power apparatus manufacturing industry and on site.
Sets are designed for dielectric tests of equipment with an air external insulation.
At Customer option additional "docking" modules can be included in the scope of set supply, which allow to use these sets for Gas(SF6)-insulated Switchgear (GIS) testing by "closed" (screened) scheme..
The complete Test Set includes:
SF6-block:
- IOG-(230 … 500 kV) test transformer;
- HV divider (coupling capacitor);
- “Air/SF6“-bushing;
- Wheeled SF6-block frame with device for block slope changing and fixing;
- Docking modules (option).
Voltage regulator block:
- Regulating transformer;
- Control and switching cabinet;
- Compensating reactor.
- Portable computer (laptop);
- Partial discharges characteristics meter (PDM 201));
- Remote measuring unit (“RMU”);
- High-frequency filter (HFF) - 2 pcs;
- Calibrating partial discharges generator (CGPD);
- Cable set.
Working table, operator's chair
Ladder for installation
Cable set with lengthes not less than 10 m
Certification and operational documentation:
- Operation manual;
- Logbook;
- Primary qualification test program;
- Primary qualification test report;
- FSUE "D.I. Mendeleev VNIIM" set certificate;
- FSUE "D.I. Mendeleev VNIIM" certificate for HV capacitive divider calibration;
- FSUE "D.I. Mendeleev VNIIM" certificate for PDM 201 instrument calibration;
- VSUE "TEST Sankt-Peterburg" certificate for VA 11 digital peak voltmeter calibration.
Sets allow to carry out tests in premises with limited floor space and ceiling height. High voltage SF6-block is easy move on testing ground of stand (see photo); block slope changing mechanism allows promptly adapt set to cealing height.
