Conventional AC test transformers are especially designed for testing objects of medium capacitance in the factory, lab or field (outdoor), particularly for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (like inductive voltage transformers).
HV AC test systems with metal tank transformer are better suited for higher test powers and higher test loads than cylinder modular type, also better for continuous duty and long duration tests, and this transformer specifically designed for all outdoor weather conditions are available.
The test transformers are situated in an enclosed and grounded metal tank with a bushing to air, filled with transformer oil inside. They are a very space-saving solution, thanks to the grounded tank, the test system can be set up close to the wall or objects within the test field, and if the positioning is outside, the HV bushing can be routed through the wall.
