NDB-DOC-3™
Distribution transformer tester 型號：NDB-DOC-3™
The NDB-DOC-3™ is a test instrument designed for distribution networks transformers from 5kVA to 3MVA. It can determine the presence of short circuits or open circuits in the distribution transformer primary winding & also short circuits on the secondary winding.
The NDB-DOC-3™ is designed to be operated without disconnecting the transformer’s secondary windings from their loads.
The NDB-DOC-3™ is designed to be operated without disconnecting the transformer’s secondary windings from their loads.
