The importance of transformer tests is all too often underrated. However, the accuracy of transducers has a huge influence on accounting systems, and tests help to significantly reduce the risk of mixing up different instrument transformers or their connections. Tests can also help identify transportation damage inside a transformer.
When it comes to detecting effects that can occur within the life cycle of a transformer such as shorted coils, loss of class accuracy due to material changes, or changes to the load, regularly scheduled tests are essential.
The Vanguard EZCT-2000A microprocessor-based Current Transformer Test Set can perform the Current Transformer (CT) excitation test, measure the CT winding resistance and CT current-ratio automatically. All of the Vanguard EZCT-2000A’s test leads can be connected to the CT output terminals, eliminating the need for lead switching during testing. Test voltage output is automatically raised and lowered by the Vanguard EZCT-2000A without any operator intervention. With up to 2000 Vac excitation test voltage available, the Vanguard EZCT-2000A can easily perform excitation tests on very large CT’s.
