Product Description
The major advantage of this Test Set-up is Minimum Active Power requirement, say for a 100KV/15A , 50KV/30A Test Set shown in the Picture the Reactive Power is 1500KVA max. in both ranges. But input AC Power requirement is less than 70KWW Because of Resonance phenomenon the Sine Wave output is Harmonics free.
Major Burning of Test objects can be avoided as the voltage falls sharply whenever there is a break down due to de-tuning of the Resonance circuit.
This Test Setup is mostly PLC based system with adequate Automation and data acquisition system. NTPL is also in the process of developing variable frequency type Series Resonance Set-up.
Enhanced Safety and ControlThis high voltage test set incorporates a robust suite of safety features, including emergency stop buttons, automatic cutoff functions, and comprehensive earthing arrangements. The microprocessor or PLC-based control ensures fully automated and dependable testing, while digital and LED displays provide accurate readouts for both voltage and current. Zero start interlock and compliance with IEC, IS, and various international standards further bolster operator safety during operation.
Customizable for Diverse ApplicationsAvailable in multiple voltage and current ratings, as well as cooling types (air or oil), this system can be tailored to meet specific testing needs. Its compatibility with both single and three-phase power supplies, variable dimensions, and mobile wheel-mounted design offer easy adaptability for laboratories, manufacturing facilities, and field testing environments. The enclosure options-fiberglass-reinforced polyester or metallic-ensure corrosion resistance and longevity.
Precision Testing PerformanceWith the ability to run continuous tests for up to 60 minutes and measure voltages up to 300 kV with 1% accuracy, this test set is ideally suited for rigorous diagnostic and routine testing of high voltage apparatus. Comprehensive protection mechanisms, along with ambient atmospheric operation and temperature resistance from -10C to +50C, ensure reliable and repeatable results under a wide range of conditions.
