Power transformers require appropriate dielectric testing to assess insulation performance and verify compliance with specified technical requirements. A lightning impulse test system provides controlled high-voltage impulses for evaluating transformer insulation under simulated lightning-related transient conditions.
The system can be engineered around transformer voltage class, rated capacity, test procedure, required impulse waveform, measuring range and factory laboratory layout. An integrated solution may include an impulse generator, charging unit, voltage divider, measuring and control system, safety interlocks and test data software.
Power transformer manufacturers, distribution transformer factories, transformer testing laboratories, electrical equipment quality departments and third-party testing institutions.
Selection depends on the transformer insulation design, voltage class, test standard, test procedure and specified impulse level. Rated voltage should be confirmed by the equipment engineering team.
Not necessarily. Voltage, energy, load characteristics, waveform requirements and the measuring system all affect suitability.
Potentially, subject to a review of clearances, grounding, shielding, power supply, safety interlocks and the dimensions of the test object.
Digital acquisition and reporting can be included where supported by the proposed measuring and control system.
