SKF BAKER HI-POT SURGE

 

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.
