RE: voltage variation tolerances
The electrical equipment shall be designed to operate correctly under full load as well as no load with the conditions of the nominal supply as specified below.....
A.C. supplies
Voltage: Steady state voltage of .9 - 1.1 of nominal voltage.
Voltage Dips: shall not exceed 20 % of the peak voltage of the supply for more then one cycle. There shall be more then 1sec between successive dips.
Frequency: .99 - 1.01 of nominal frequency continuously,
.98 - 1.02 short-time.
