Arcvis

The apparatus for arc resistance tests - at high-voltage and low current intensity - of insulating materials, enables to carry out the foreseen tests quite automatically. Cycles sequence, both at interrupted and continuous arc, is controlled and programmed by an electronic device, which prevents the operator to act manually and within the pre-fixed-times on the commuters. In such a manner the test gets developed according to the sequence established by the standards. Once the test is over, the operator just has to examine the specimen and see whether the surface involved between the electrodes shows a conducting continuous trace caused by high-voltage discharges. Tests can be performed on thermoplastic on thermosetting resins Hat specimens and on other insulating materials similar to them.
