FAQ
Q1: What types of high-voltage equipment can the SXBP system test?
A: It can be used for AC withstand voltage testing of XLPE cables, GIS, power transformers, instrument transformers, CVTs, bushings, insulators, coupling capacitors, and other capacitive high-voltage apparatus.
Q2: Can this system be used for on-site testing?
A: Yes. The SXBP system is designed for field applications. Its modular configuration and relatively low input power requirements make it suitable for use in substations, construction sites, and outdoor testing environments.
Q3: What power supply is required for operation?
A: The system is typically operated from a 380 V, 50 Hz/60 Hz industrial power supply. Because series resonance multiplies the effective test voltage, the required input capacity is much lower than the apparent test capacity.
Q4: Is the frequency adjustable for different test objects?
A: Yes. The output frequency is adjustable from 20 Hz to 300 Hz, which allows the system to adapt to different capacitive loads and meet the test frequency requirements of various high-voltage apparatus.
