Distribution transformer tester ADOC-3

Distribution transformer tester

The ADOC-3 is a device 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 works without disconnecting the secondary windings of the transformer from its loads. The instrument requires an electrical connection to the primary bushings and thus shows the diagnostic readings with a visual and audible signal.

The ADOC-3 allows to analyze if it is safe to re-energize the transformer after an interruption such as line failure or storm (the transformers must be recharged regularly and if they are connected to a faulty circuit they run the risk of breaking when energized again with a lot of energy).

 

The kit includes:

  • the test instrument
  • test leads with clamps
  • a bag for transport.

 

Main features:

  • For de-energized transformers from 5kVA to 3MVA.

  • Compact and lightweight design

  • Detects the primary short circuit of the transformer, open circuit and secondary short circuits.

  • Contact measurement in 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.
