Sodium flood light off during large motor starting
Sodium flood light off during large motor starting
(OP)
I have traced the reason why sodium flood light is off during large motor starting. When large motor is starting sodium flood light is turned off and it is back on after starting/getting stable condition of motor.
Do anybody know why it happen and how I can make remedy to it ?

However, if the voltage tap selected happens to be lower than the normal system voltage there is a danger of overheating / failure of the ballast. This method is used widely for the street light fittings at the tail end of the circuit.

Motor starting method is Star-Delta starting but problem is not created by voltage drop. It seems that harmonics kills ballast during starting. In this condition, is there any other solution against problem ? At the moment starting method can not be changed.

A decent meter should catch the voltage dip, in most cases, if an oscope is not available.
