Advanced HV Resonant Test System
Mobile Variable Frequency HV AC Resonant Test System for Transformers, Cables and Switchgears Testing
Product Overview
The SXBP Variable Frequency HV AC Resonant Test System provides an efficient and safe solution for AC withstand voltage testing of substation equipment (10kV-500kV). Utilizing core series resonant technology, this system delivers superior performance with three key advantages:
- High-Output, Low-Input: Requires only a fraction of conventional test set input power to generate high test voltage, reducing size, weight, and site power demand
- Superior Waveform: Acts as a natural filter, producing exceptionally pure sinusoidal test voltage (low THD) that protects sensitive equipment from harmonic damage
- Inherent Safety: Resonant circuit inherently limits fault current during breakdowns, preventing catastrophic damage to test objects
Key Features
- Uncompromised Waveform Purity: Sine wave output with Total Harmonic Distortion (THD) ≤ 1% protects sensitive equipment and ensures international standard compliance
- High Efficiency & Portability: Quality Factor (Q) ≥ 30 enables minimal input power from standard 220V/380V single-phase sources for high kVA output
- Intrinsic Safety by Design: Resonant circuit limits fault current to safe values (≈1/Q of test current) with controlled arc quenching
- Robust & Reliable: Supports continuous operation at full-rated load for over 60 minutes for extended test procedures
Applications
- Power Transformers & Reactors
- High-Voltage Power Cables (XLPE, PILC, etc.)
- Gas-Insulated Switchgear (GIS) & Circuit Breakers
- Insulators & Bushings
- Instrument Transformers (CT, CVT, PT)
- Rotating Machines (Generators, Motors)
- Other High-Voltage Electrical Apparatus

Technical Notes
Model SXBP-27/54/108-108: SXBP is the model 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 to increase test voltage.
