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 Control

This 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 Applications

Available 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 Performance

With 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.

FAQ's of AC High Voltage Test Set (Series Resonance Type):


Q: How does the AC High Voltage Test Set (Series Resonance Type) operate during high voltage equipment testing?

A: The test set utilizes a series resonance circuit to efficiently generate high AC voltages up to 300 kV for testing cables, transformers, GIS, and other equipment. The automated control unit (microprocessor or PLC-based) manages test parameters and ensures consistent operation, while the digital/LED display provides real-time voltage and current readings.

Q: What safety features are included in this high voltage test set?

A: The system is equipped with multiple safety provisions such as an emergency stop button, automatic cutoff mechanism, over voltage and over current protection, a zero start interlock, and comprehensive earthing. These measures help protect both the operator and the equipment during testing processes.

Q: When is this test set typically used, and what types of equipment can it test?

A: This test set is used during routine and type testing of high voltage apparatus, such as power cables, generators, gas-insulated switchgear (GIS), and transformers. It is suitable for both manufacturing quality control and field diagnostics, providing reliable assessment of insulation and operational integrity.

Q: Where can the AC High Voltage Test Set be installed and used?

A: Thanks to its portable, wheel-mounted design and customizable options (size, voltage, cooling, enclosure), the test set can be easily installed in testing laboratories, at manufacturing facilities, or on-site for field testing. Its corrosion-resistant and moisture-proof casing ensures durability wherever it's deployed.

Q: What are the benefits of using a series resonance type AC high voltage test set?

A: Using the series resonance principle enhances testing efficiency by minimizing power draw and delivering stable, regulated high voltage, which leads to more accurate results.
