Product Description
Product Overview

The Variable Frequency Series Resonant Test System is designed for high-voltage AC withstand testing of capacitive electrical equipment. By adjusting the output frequency to achieve resonance between the high-voltage reactor and the capacitance of the test object, the system can generate the required test voltage with reduced input power demand compared with conventional test arrangements of comparable output capability.

The system typically consists of a variable frequency power supply, excitation transformer, high-voltage reactor, capacitive voltage divider and control system. The exact configuration depends on the required test voltage, load capacitance, test frequency and application.

Designed for power utilities, electrical equipment manufacturers, high-voltage laboratories and field testing contractors, the system can be engineered for different voltage levels and site requirements.

Key Testing Functions
  • High-voltage AC withstand voltage testing.
  • Variable frequency resonance control.
  • Test voltage measurement and monitoring.
  • Automatic frequency tuning, where supported.
  • Overvoltage and overcurrent protection, depending on configuration.
  • Customizable reactor combinations for different test loads.
Typical Applications
  • XLPE power cable testing.
  • Power transformer AC withstand testing.
  • GIS and switchgear insulation testing.
  • Generator and motor insulation testing.
  • Bushings, busbars and other capacitive electrical equipment.
How We Address Common Challenges
Challenge 1: Conventional test equipment requires a large power supply.

A properly matched series resonant system can reduce the input power required for high-capacitance test objects.

Challenge 2: A single configuration may not cover every test object.

The system can be engineered around different test capacitances, voltage requirements and reactor combinations.

Challenge 3: Buyers need confidence before ordering.

We recommend providing a technical proposal based on the customer's equipment ratings, capacitance, test voltage, test duration and site power supply.

Frequently Asked Questions
Q1: What equipment can be tested with a series resonant test system?

Depending on the configuration, it can be used for power cables, transformers, GIS, generators, switchgear, bushings and other capacitive test objects.

Q2: Can the system be customized?

Yes. Rated voltage, capacity, reactor configuration, control functions and accessories can be specified according to the project requirements.

Q3: What information is needed for a quotation?

Please provide the equipment under test, rated voltage, required test voltage, load capacitance or cable length and cross-section, test duration, available power supply and applicable standard.

Q4: Can it be used for field testing?

Yes, if the selected configuration is designed for field deployment and the site has suitable space, grounding and power facilities.

Q5: How do I select the correct system capacity?

The selection should be based on the required test voltage, load capacitance, resonant frequency range, current, test duration and the manufacturer's validated configuration calculations.
