225kVA/25kV PD-Free AC Series Resonant Test System
The SXBP PD-free AC Series Resonant Test System provides an optimized solution for on-site and factory AC withstand voltage testing of high-capacitance loads in substations, including power cables, GIS, transformers, and generators (rated up to 500kV). Operating on the series resonance principle, the system automatically tunes to the resonant frequency of the test loop, fundamentally solving the challenges of testing large capacitive loads while delivering clean test waveforms and built-in current limitation for superior safety and accuracy.
Key Features
- High-Voltage Output: 27kV, 54kV, and 108kV ratings for testing equipment up to 500kV class
- Smart Frequency Sweep: 30-300Hz automatic tuning for optimal testing of cables, GIS, transformers, and more
- Lab-Grade Waveform: Exceptionally clean sine wave output (THD ≤ 1%) for accurate and reliable test results
- Plug-and-Play Portability: High Q-factor design enables powerful output from standard single-phase wall outlets (220V/380V)
- Fail-Safe Protection: Comprehensive electrical protection with unique "Breakdown Current Limitation" capability
Applications
- 6kV ~ 500kV crosslinking polyethylene cable AC withstand voltage testing
- 35kV ~ 500kV GIS AC withstand voltage testing
- 10kV ~ 500kV switch, bus, casing and other AC withstand voltage testing
- 10kV ~ 500kV power transformer power frequency withstand voltage testing
- 10kV ~ 500kV PT and CT power frequency withstand voltage testing
- Generator power frequency overvoltage withstand testing
- 10kV ~ 500kV power capacitor withstand voltage testing

Note: Model SXBP-27/54/108-108, SXBP is the model of series, 27/54/108 indicates: voltage of one reactor (kV) / voltage of two reactors in series connection / voltage of four reactors in series connection. 108 is the total capacity (kVA). For equipment with smaller capacity and lower voltage, additional reactors can be added to increase capacity, and additional dividers can be added to increase test voltage.
