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.

Features

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

Current transformer testing is an important part of the commissioning and maintenance of power systems. Protective relays can only operate adequately, under normal & fault conditions, if they receive the correct secondary current from the current transformaers. Therefore accurate CT testing to evaluate their performance under all conditions is essential to assure reliable operation of the protection system.

Automatic Ratio Testers

The ARTs can also run automatic detection the winding confi gurations. The real 3 phase output allows for easy testing of phase regulating and phase shifting transformers (no need for jumper installations to short windings). The high test voltage (up to 275 Volts) is particularly interesting as it will generate higher excitation currents for larger fl ux, and therefore strong refl ected test signals are generated for high accuracy measurements even on large power transformers and transformers with tertiary windings.

Grounding Jumper Assembly Tester

The GET-401 exclusive design uses test rods that are connected to the ndb Technologie DRM-1A micro ohmmeter in a manner to provide you with ``point to point`` results. Measures include the clamps contact point. Clean, low resistance connections are a must, changes in the value of a low resistance element are one of the best and quickest indications of degradation taking place between two contact points.
