FUNCTIONALITY
CSSPSS’s HT Panel AMC services function as a comprehensive healthcare program for your high voltage assets. Our systematic approach involves scheduled site visits where our engineers conduct thorough inspections, cleaning, and tightening of busbars and cable connections. We perform critical diagnostic tests such as contact resistance measurement, insulation resistance tests, and Vacuum Circuit Breaker (VCB) timing tests. By utilizing thermal imaging to detect hotspots and analyzing transformer oil for dielectric strength, we identify potential faults before they escalate, ensuring your HT panel operates safely and efficiently under high load conditions.

Frequently Asked Questions
HT panels should ideally undergo preventive maintenance every 3 to 6 months. However, the frequency can vary based on the operational environment and load criticality. CSSPSS offers flexible schedules to match your specific needs.
Our VCB servicing includes cleaning of the bottle, checking the vacuum integrity, lubricating the mechanism, verifying the contact gap, and performing timing tests to ensure the breaker operates within safe limits.
Thermography helps detect "hotspots" caused by loose connections or overloaded circuits that are invisible to the naked eye. Early detection prevents thermal runaway, which can lead to catastrophic fires or explosions in high tension systems.
Yes, for HT panels containing oil-filled transformers or switchgear, we include oil sampling and testing (BDV test) as part of the comprehensive AMC to monitor dielectric strength and moisture content.
Absolutely. CSSPSS provides 24/7 emergency support for all AMC clients. Our rapid response team is equipped to handle HT faults and restore power as quickly as possible.
