Distribution Transformer Tester The DOC-2000 is intended for de-energised distribution transformer testing. It can determine the presence of short circuits or an open circuit in the distribution transformer primary winding and also short circuits on the secondary winding. The DOC-2000 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 No need for disconnecting transformer secondary windings therefore saving time Reduces risks of hazards when putting fuses back online when the transformer windings are shorted Conformity with the requirements for safety (IEC-TC78 ) Transformers up to 167 KVA single or three phase (Pole mount or Pad mount) Measurement by contact on the transformer primary bushing and neutral/ground Used on de-energized transformers Detects primary transformer short-circuit, open circuit, & secondary short circuits Visual and audible warning. Automatic self-test & Auto shut-off Low battery indicator Operating temperature range -25°C to 55°C EASY OPERATION The instrument requires an electrical connection to the primary bushing and the system ground (neutral). The DOC-2000 displays the diagnostic readings with a visual and audible signal. The DOC-2000 kit includes the test instrument, contact electrodes ( Pole mount hook & Pad mount pin ) and a carrying case. ndb Technologies inc. • 1405 St-Jean-Baptiste, office 111 • Quebec (QC) G2E 5K2 - Canada • Tel: 1(418)877-7701 Fax: 1(418)877-7787 Email: [email protected]

TECHNICAL SPECIFICATIONS Supported transformers up to 167 KVA single or three phase Hook type probe and pin type probe Operating temperature Power supply OPERATION Linemen crews are called on to re-energize transformers regularly, whether it’s after storms or when line faults occurs etc... The reasons for the outages are not always obvious, but the power needs to get back on. When damaged or connected to a faulty circuit, the transformers can rupture with massive amount of energy when attempting to re-energize. In order to make a better decision whether it is safe to re-energize the transformer...
