In modern power systems, electrical equipment faces increasingly complex operating environments. Lightning strikes, switching operations, and transient overvoltage events can create severe electrical stress on transformers, switchgear, cables, and other high voltage components.

To ensure equipment reliability, manufacturers and testing laboratories must perform accurate lightning impulse testing before products are delivered to the market. However, impulse voltage testing in real-world environments is often affected by electromagnetic interference (EMI), grounding conditions, and measurement instability, which may lead to inaccurate test results.

The SXCY Impulse Voltage Generator from Sansion Power provides a professional high voltage testing solution designed to improve impulse test accuracy and reliability under challenging electromagnetic conditions.

Although impulse voltage tests are usually performed in controlled laboratory environments, unexpected interference sources can still affect measurement accuracy.

Modern substations and industrial facilities contain many electronic devices, such as frequency converters, power electronics systems, and control equipment. These devices may generate electromagnetic noise that affects impulse measurement signals.

Possible consequences include:

• Distorted impulse waveform
• Incorrect measurement results
• Repeated testing requirements
• Increased project time and cost

For transformer manufacturers and high voltage laboratories, obtaining reliable test data is essential for product qualification and safety verification.

A stable grounding system is critical during high voltage impulse testing. Poor grounding conditions may introduce unwanted interference into measurement circuits, affecting voltage waveform analysis.

The SXCY Impulse Voltage Generator adopts optimized grounding design and protection technology to reduce external interference and improve measurement stability.
