Machines for transformers testing

For testing transformers, Risatti makes a full range of machines for electrical transformers, single and three-phase, toroidal transformers, in their many forms, both in terms of power and voltage and production volumes.

In fact, the equipment ranges from:

  • simple tests for small transformers on single stations or alternating double ones
  • to complex highly automated tests with the application of robots and laser marking systems for high production volumes.

The case of tests on high power or high voltage transformers is different where, given the low number of pieces produced, the tests are mainly individual and have very distinctive features.

Our machines

We offer a wide range of machines for heads and tests for different sectors of use.

The tests

The equipment, exclusively designed and manufactured by us, embraces the entire electromechanical and electrotechnical sector and the sectors related to preventive maintenance, repairs and rewinding.
Residual voltage test is used to detect the presence of residual voltage in a system, after the main source of power is disconnected.
The AC dielectric strength test is performed by setting an acceptability threshold of the maximum current.
Testing the electrical resistance of a winding is essential and is performed to measure the resistance of a winding.
The SURGE test is the most reliable method to test the insulation of winding systems and can also be used to test partial discharges.
The DC insulation resistance test evaluates the quality of the insulators, the possible presence of humidity and pollution.
