The SXBP Variable Frequency Series Resonance Test System is engineered for demanding AC high-voltage testing where conventional test methods may become less practical due to the large capacitance of the equipment under test.
Using variable-frequency series resonance technology, SXBP creates a controllable high-voltage AC testing environment for power cables, GIS, transformers, circuit breakers, CTs, VTs, CVTs and other high-voltage equipment.
