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 and also short circuits on the secondary winding without disconnecting it from its load.

• Single phase, Yn, Delta, Padmount or 3 phase banks, Medium voltage dry type, etc.
• Single test for all windings
• No need to remove sec. leads/loads.
• From 1kVA to 3MVA
• Easy interpretation (Short, OK or Open)
• Includes protective rubber boot.
• Compact, lightweight, battery operated.Based on years of surveys
