dear mnewman,
it took me alot time to find the standard.
I'm not familiar with IEC much. Some design books propose voltage drop during motor starting is 15%.
thank you for your advice.
By the way, can you tell me the code of IEC standard for voltage drop (in short time) at the switchobard for...
hi 7anoter4,
You said "According to IEC 34-12(IEC 60034-12?) up to 200 hp 19.5% voltage drop from motor rated voltage at start it is ok"
is there any mistake?
IEC 60034-12 doesn't specify any thing about voltage drop for motor starting, it only specifies the torque requirment.
am i wrong?
it...
hi everyone,
can anyone tell me the specific IEC requirement of voltage drop at the motor terminal when motor starting.
for a 4.5MW/6.6kv Motor, how much is the maximum permissble volt-drop when motor starting per IEC?
Please help me,
thank you
