[Transformerpreventive testing]
Routine tests including DC resistance, insulation resistance and AC withstand voltage are conducted on power transformers to verify their compliancewithoperational standards.
[Powercable preventive testing]
Routine tests including insulation resistance, DC withstand voltage and leakage current are conducted on power cables to verify their compliance with operational standards.
[Busway insulation resistance testing]
Regular insulation resistance testing of busways enablesa better understanding of their operational status.
[Insulation resistance testing for low-voltage cabinetbusbarsystems]
Regular insulation resistance testing of the low-voltage busbar system allows the insulation aging condition of low-voltage electrical components to be identified.
[Powersystem harmonicdetection]
Harmonics pose significant hazards to power facilitiesand exert varying impacts on different electrical equipment,so their values should be regularly tested to verify compliance with standards.
[Powercapacitorcommissioning]
Power capacitors are capacitive loads. During operation,their performance graduallydegrades, service life shortens and capacitance decreases withan increase in service life.Regular testing and inspectioncan improve the powersupply quality and the power factor of the power grid.
[Earthing resistance testing]
Toensure the normal operation of power supply equipment and personal safety,the earthing resistance of all power supply equipment shallbe tested regularly (Electrical parameter: Earthing resistance R <= 4 \Omega required).
