Product Description
SXBP 3750KVA/300kV Variable Frequency AC Resonant Test System
A variable frequency AC resonant test system applies the resonance principle to high-voltage AC withstand testing. By adjusting the operating frequency to suit the test circuit, it supports insulation testing for compatible electrical equipment.
High-voltage testing laboratories can evaluate this type of system for testing programs involving suitable capacitive loads. The selection process should take into account the laboratory's test scope, equipment range, operating environment, and applicable testing procedures.

FAQ
Q1: Why do laboratories use AC resonant test systems?
They provide a resonance-based method for AC withstand voltage testing of suitable high-voltage electrical equipment, depending on the laboratory's testing scope.
Q2: How does series resonance work?
The system adjusts the frequency so the inductive and capacitive effects of the test circuit can reach resonance. Under suitable conditions, this reduces the reactive power required from the input supply.
Q3: Which test objects may be suitable?
Potential applications include power cables, GIS, switchgear, and other compatible high-voltage equipment. Each test object should be assessed individually.
Q4: What should a laboratory consider when selecting a system?
Consider the types of equipment to be tested, test procedures, required test voltage, test duration, electrical characteristics, and laboratory conditions.
Q5: Can the system support different laboratory testing needs?
The configuration can be evaluated against the laboratory's planned test scope. The final arrangement depends on the equipment under test and confirmed technical requirements.
