Profile:
Tank Type Long-Running HV AC Test Transformers are especially designed for testing objects of medium capacitance in the factory or outdoors. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (heavy corona, wet & pollution tests) or when the load is of inductive kind (inductive voltage transformers). The system duty cycle can be freely chosen and is insured by adding radiators or forced oil cooling to the transformers. These systems are also suited for continuous duty, long duration tests.
Features:
- Specially designed bushings for indoor or outdoor use
- Large range of applications
- Low acoustic noise level (ca. 65 dBA)
- Sophisticated protection features for optimal test object and personnel protection
- Power compensation inductance reduces the power required on the primary (LV) side of the test system
- Possibility to use an external oil expansion vessel or protection relay
- Suited for continuous duty, long duration tests
