Product Description

The Lightning Impulse Voltage Generator for Power Transformer Testing is designed specifically for transformer manufacturers and high-voltage laboratories requiring controlled impulse voltage testing.

Power transformers are exposed to transient overvoltages during actual operation. Lightning impulse testing is therefore used to verify whether transformer insulation can withstand specified transient electrical stresses.

The system generates a controlled high-voltage impulse and measures the resulting waveform to evaluate the transformer's insulation performance.

Transformer impulse testing is a major application area identified across current industry product pages.

Why Transformer Manufacturers Need It

The customer's major concern is usually not simply:

“Can your generator reach 1200 kV?"

Instead, the real engineering questions are:

• Can the required waveform be achieved under the actual test load?
• Can the system handle the transformer's capacitance?
• Can the waveform be measured accurately?
• Can the system meet the required standard?
• Can the test data be automatically recorded?
• Can the equipment be integrated into the existing HV laboratory?

FAQ

Q: What information is required to design a transformer impulse test system?

A: Recommended information includes transformer voltage class, rated voltage, insulation level/BIL, test voltage, transformer capacity, test standard and laboratory dimensions.

Q: Can you provide 1200 kV or higher systems?

A: The system voltage and energy can be engineered according to the project requirements. High-voltage impulse systems are available in a wide range of configurations, including UHV applications.

Q: Can the system be used for transformer type testing?

A: Yes. The configuration can be designed for applicable transformer dielectric and impulse testing requirements.
