Kryteria oceny stanu technicznego izolacji zwojowej metodą rozmytej fali napięciowej

Condition diagnostic of turn-to-turn insulation, using the method of fuzzy wave is based on breaking the passage of current in the circuit with tested coil or winding what generate a voltage wave. This voltage is exactly the same on each turn. The frequency of generated voltage depends solely on the parameters of the winding, not on the supply and parameters of insulation, what is described in [1] and [3]. Described method is a supplement of diagnostic method of main insulation with DC voltage, named method of prof. Glinka.
