Distribution transformer tester
The NDB-DOC™ is a test instrument designed for distribution networks transformers from 10kVA to 2500kVA. It can determine the presence of short circuits or an open circuit in the distribution transformer primary winding & also short circuits on the secondary winding. The NDB-DOC™ is designed to be operated from an arial device or from the ground at the end of a hot stick without disconnecting the transformer’s secondary windings.
