From February 21, 2020 Ximex electrical laboratory expanded its scope of activities and received a permit to perform high-risk work: testing equipment with voltages above 1000V (electrical equipment of power plants and networks, technological electrical equipment.)
We can now offer our customers a range of testing services.
Comprehensive testing of a transformer substation, a complete transformer substation, a complete switchgear for outdoor installation, which includes the following types of tests:
- High-voltage testing of switchgear with power frequency voltage. Switchgear 6(10) / 0.4 kV are tested - support, bushing insulators, current transformers, vacuum circuit breakers, disconnectors and other equipment according to the manufacturer's standards and the rules for electrical installations;
- Comprehensive testing of a power transformer 6(10)/0.4 kV, determination of the winding connection group of three-phase transformers and the polarity of the outputs of single-phase transformers, measurement of the resistance of transformer windings to direct current, measurement of current and short circuit losses;
- Testing of a high-voltage cable line feeding the transformer;
- Adjustment of relay protection and automation devices, which includes checking secondary protection, control and signaling circuits, automatic circuit breakers, high-voltage circuit breaker control circuits, power transformer protection, automatic reserve switching circuits, etc.
Carrying out electrical tests of protective equipment:
- Dielectric gloves
- Dielectric boots and galoshes
- Hand isolating tool
- Insulating and measuring rods
- Insulating and measuring pliers
- Voltage indicators
- Voltage indicators for phasing
