DC Hi-POT TEST
After the winding is done, it is used to determine the voltage resistance of the windings against the chassis
and other phases.
Winding V = (2 * U + 1000) * 0,65 * 1,7 Used to give DC voltage
It is tested whether the insulation materials can fulfill the task in the network conditions due to
manufacturing and workmal errors.
Surge Test
The high-voltage surge comparison test can be performed on the spool-
It is tested to see if the voltage drops in the conditions
It is based on the principle of generating a damped wave by generating a parallel LC circuit by discharging
the high voltage voltage to the coil by the capacitor
The damped wave reflected from the coils is visible on the oscilloscope screen and gives information about
the state of the signaled coils.
