Lightning Impulse Generator for GIS and Switchgear Testing, High Voltage Impulse Test System for Circuit Breaker, Insulator, Bushing and HV Apparatus

Product Description

The Lightning Impulse Generator for GIS and Switchgear Testing is designed for evaluating insulation performance of high-voltage switching equipment and related components.

The system applies controlled impulse voltage to the test object and records the resulting waveform for analysis.

Test Objects

• GIS
• AIS
• Circuit Breakers
• Disconnectors
• Switchgear
• Ring Main Units
• Bushings
• Insulators
• Instrument Transformers
• HV Components

Testing Functions

• Lightning impulse test
• Switching impulse test
• Chopped impulse test
• Insulation withstand test
• Waveform recording
• Voltage measurement
• Automatic data analysis
• Test report generation

Customer Pain Points

GIS testing requires appropriate test configuration.

The customer needs to consider:

• GIS rated voltage
• Test voltage
• Test object capacitance
• Test arrangement
• Required waveform
• Measurement system
• Laboratory clearances
• Safety system

A generic “one-size-fits-all" generator is therefore not always the appropriate solution.

FAQ

Q: Can GIS be tested with the same impulse generator used for transformers?

A: The same generator technology can be used, but the complete test configuration must be designed according to the GIS test object and required test conditions.

Q: Can switching impulse be tested?

A: Yes, when the generator and wave-shaping network are configured for the required switching impulse waveform.
