VRD stands for Voltage Reduction Device
A VRD reduces the maximum open circuit voltage across the output terminals to below 15 volts
This is a safety requirement of most mines in South Africa when the unit is to be operated underground or in damp conditions
The presence of a VRD can however cause difficulty in the striking and re-striking of the arc with less skilled operators. This is because the machine has to rapidly change from the reduced open circuit vol tage of below 15 volts to the open circuit voltage of around 56 volts necessary to strike the arc
