Tank Type HV AC Test Transformers are especially designed for testing objects of medium capacitance in the factory, indoor or outdoor. 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.
The neutral end of the high-voltage winding is brought out insulated. The high-voltage end is brought out through the transformer bushing. Either an oil-air or oil-SF6 bushing can be used depending of the application. The bushing is chosen according to the ambient conditions and is capacitively graded for the upper voltages. Upon request, the bushing can be fitted with a measurement tap. An aluminium top electrode is placed on the bushing to allow a PD free operation up the rated voltage. An angle with a multi-contact plug allows to connect mechanically and electrically a high voltage connection.Transformer specifically designed for all outdoor weather conditions are available.
