TOV Temporary Overvoltage Test System

TOV Temporary Overvoltage Test System

The HVEX Temporary Overvoltage (TOV) Test System verifies the withstand capability of equipment against TOVs, caused by factors such as grounding faults and transformer energization. Designed to meet customer requirements, it offers personnel training, excellent cost-effectiveness, a two-year warranty, and domestic manufacturing. Customizable to meet specific demands, it is applicable to TOVs in high, medium, and low voltage systems according to the ABNT NBR IEC 61643-1 standard. The supply includes a TOV test module, a power transformer, and a TOV power source. Keywords: Temporary overvoltage, overvoltage, TOV, Withstand capability, ground faults, transformers, high voltage, medium voltage, low voltage, load rejection, ferroresonance. Standards: ABNT, NBR, IEC 61643-1.
