Distribution transformer tester ADOC-3

Distribution transformer tester ADOC-3


The ADOC-3 is an equipment that has been designed to test distribution network transformers from 5 kVA to 3MVA. This instrument can determine the presence of:

  • Short-circuits or open circuits in the primary winding of the distribution transformer

*short circuits in the secondary winding

The ADOC-3 operates without disconnecting the secondary transformer windings from their loads. The instrument requires an electrical connection to the primary bushings and thus displays the diagnostic readings with a visual and audible signal.

The ADOC-3 makes it possible to analyse whether it is safe to re-energise the transformer after an interruption such as a line fault or a storm (transformers must be regularly recharged and if connected to a faulty circuit they are at risk of breaking when re-energised with a large amount of energy).

The kit includes:

  • The test instrument
  • Test cables with clamps
  • A bag for your transport.
  • Main characteristics:
  • For de-energised transformers from 5kVA to 3MVA.
  • Compact and lightweight design.
  • Detects transformer primary short, open circuit and secondary short.
  • Contact measurement on the primary bushing of the transformer, without the need to remove the secondary cables.
  • Visual and audible warning.
  • Automatic self-test and automatic shutdown.
  • Low battery indicator.
  • Distribution Transformer Tester
