Routine maintenance focuses on precision protection and component inspection, and common faults can be handled as follows:
Monthly inspection: Calibrate the built-in standard resistor and voltage reference; test whether the overcurrent and overvoltage protection functions are normal;
Quarterly maintenance: Clean the heat dissipation vents and test terminals with a dry cloth (do not use water or chemical cleaners); check whether cables and terminals are loose or damaged;
Annual calibration: Contact a qualified metrology institution for comprehensive calibration to ensure accuracy meets standards.
It is a high-integration precision testing instrument designed for 10kV/35kV/110kV high-voltage (HV) switchgear and distribution cabinets. It can complete one-stop testing of core items including insulation withstand voltage, loop resistance, circuit breaker mechanical characteristics, relay protection, and partial discharge without repeated wiring.
Working principle: Connect to the HV side, low-voltage side, control circuit and grounding terminal of the HV cabinet once. The embedded industrial computer automatically switches test circuits through a relay matrix, outputs standard test signals (high voltage/large current), collects data through a high-precision sampling module, processes it in real time via DSP technology, compares it with IEC 62271 and GB 3906 standards, and generates a qualification test report.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
