AC Resonant Test System measure dielectric breakdown and dielectric strength of electrical equipment and insulating materials at all levels of commercial power frequencies.
AC Resonant Test Systems consist of two main components: a High Voltage Reactor and Regulator. The system's controls may be contained within the regulator cabinet or in a separate console. The component design depends on customer requirements and may include options necessary to perform at very high voltage levels. Substantial safety features are built-in to protect personnel and equipment from potential injury, loss, or damage. To protect against flash-overs or short circuits, our units have an adjustable electronic overload circuit. The test sets have an input circuit breaker and backup overload protection in the primary input of the high voltage transformer.
AC Resonant Test System are used where the load is largely capacitive with low loss such as power cables, gas insulated switch-gear, generator winding, motors, and dry test of insulators strings. Options may include partial discharge testing and tan measurements. This test sets are built for indoor or fair weather outdoor operation, but may be designed to operate in adverse outdoor conditions. This system also builds transportable variable frequency AC resonant test systems for field testing of installed power cables or generator winding, and other equipment. These units can be used in field test where reduced power consumption is required.
