Description

Product Introduction

The SXBP Variable Frequency Series Resonance Test System provides a controlled and efficient approach to high-voltage AC withstand testing where conventional high-power test sources may become impractical. The system combines a variable-frequency power source, excitation transformer, resonant reactor and protection components to create a controllable resonant circuit. By tuning the operating frequency to the characteristics of the test load, high AC test voltages can be generated for demanding insulation verification.

FAQ

  1. What is the difference between the SXBP system and a conventional AC hipot system?
    The SXBP system uses a resonant circuit in which the test object's capacitance participates in the testing process. The operating frequency is adjustable, allowing the system to establish resonance according to the characteristics of the load.
  2. Is SXBP suitable for long cable testing?
    Yes. Long HV/EHV cables are one of the typical applications because their distributed capacitance makes resonance testing particularly useful.
  3. What cable voltage classes can be covered?
    The system can be configured for applications involving 110 kV, 220 kV, 500 kV and other voltage classes, subject to the actual test parameters.
  4. Can SXBP be used for GIS testing?
    Yes. It can be used for AC withstand testing of GIS and SF6-insulated switchgear in appropriate configurations.
  5. Can the system test transformers?
    Yes. A suitable configuration can be developed according to the transformer's required test voltage, capacitance, test duration and other electrical parameters.
