Lightning Impulse Test System for Power Transformers Factory Testing Equipment

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.

• Lightning impulse testing of transformer insulation
• Full-wave and chopped-wave tests, as required
• Switching impulse testing for applicable transformer ratings and procedures
• Waveform recording and parameter evaluation
• Test data documentation for quality control

Power transformer manufacturers, distribution transformer factories, transformer testing laboratories, electrical equipment quality departments and third-party testing institutions.

• Whether the system is suitable for their transformer voltage classes.
• Whether it supports the required routine, type or special tests.
• Whether the test area and safety layout are adequate.
• Whether factory acceptance testing, installation and commissioning are included.
• Whether software can generate the required test records.
