Combating Extreme Heat: How SXCY Impulse Generators Ensure Transformer Insulation Safety via ±1% Voltage Stability

In regions like Saudi Arabia and the UAE, ambient temperatures frequently exceed 50°C. Extreme heat accelerates the aging of oil-paper insulation in transformers and significantly alters the breakdown characteristics of air gaps. For impulse testing, fluctuations in air density directly cause charging voltage drift.

Without superior voltage regulation, the nominal waveform deviates from standards. The SXCY Series Impulse Voltage Generator limits charging voltage instability to ≤±1%, effectively neutralizing thermal disturbances and ensuring baseline consistency for Lightning Impulse (LI) tests.

Maintaining precision under extreme conditions relies on the SXCY series' robust design:

• Automatic Constant Current Charging: A high-precision feedback loop ensures consistent residual voltage even under significant grid voltage fluctuations.
• Minimized Peak Oscillation (≤ 5%): As dielectric loss increases in heat, the SXCY optimizes circuit inductance to keep oscillations under 5%, preventing "false breakdowns" caused by high-frequency overshoot.
• Synchronization Error < 2%: Combined with a 10% to 100% Un ignition range, the system maintains high firing precision even when heat or dust affects spark gap sensitivity.

For B2B users in the Middle East, the SXCY series provides distinct advantages:

1. 500kV Substation Maintenance: With 90% lightning wave efficiency, it reduces energy loss during field operations, supporting continuous 300s/cycle charge-discharge tasks.
2. Digital Measurement & Analysis: The integrated system records every impulse current and voltage waveform, utilizing digital filtering to eliminate thermal noise and generate IEC 60060-compliant reports.

In the context of Middle East power expansion, the SXCY generator acts as a "precision ruler" for insulation strength. With ±1% voltage stability and 2~5μS precise chopping, it provides a solid technical guarantee for the long-term reliability of power equipment under extreme thermal environments.
