Distribution transformer tester
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.
- De-energized transformers from 5kVA to 3MVA
- Measurement by contact on the transformer primary bushing
- Detects primary transformer short-circuit, open circuit, & secondary short circuits
- Visual and audible warning
