NDB-DOC™
Distribution transformer tester 型號:NDB-DOC™
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.
-
- For transformers up to 833kVA single phase or 2500kVA three phase (Pole mount or Pad mount)
- Measurement by contact on the transformer primary bushing and Neutral/Ground
- Used on de-energized transformer
- Detects primary transformer short-circuit, open circuit, & secondary short circuits
- Visual and audible warning Automatic self-test & Auto shut-off
- Low battery indicator
