|Mechanical Condition||Excellent (No problems or history of failures)|
The main supply Transformer is specified in a way that the supply reactance works as a limiting factor of peak asymmetric fault current; and non-compliance with this specification can be destructive for Rectifier semi-conductor devices. Over current protection is provided. Line current measuring CT’s are constantly measuring the line input current and this information is fed to trip section of control card. Where a reference is set.
