Essential equipment for measuring and analyzing electrical coils Currently, many methods are used to measure and analyze characteristics of electric motors and generators, but there are 3 pieces of equipment that are essential for measuring electrical quantities and analyzing constructive physical characteristics, and mainly insulating characteristics of these items.
The use of Milliohmmeter, Megohmmeter and Surge Test equipment are basic methods that guarantee the safety and operational longevity of these machines.
This equipment individually measures or analyzes different characteristics of the winding and its dielectric insulation; together they identify a range of faults that compromise the correct functioning of the machines.
Among the main faults that are identifiable, we can list the main ones:
Variations in electrical resistance of coils between phases;
Low electrical insulation between phases or phase/ground;
Short circuits between turns of the same coil;
Inductance variations between phases;
Problems related to magnetic iron core sheets;
These failures can lead to anything from a malfunction to the complete burnout of the machine. Avoiding these problems and/or identifying them at an early stage is important so that we keep the machines operational in a preventative manner and at the same time ensure operational safety for employees. that work on these machines.
