How to choose the capacity of the voltage stabilizer:
Principles
The voltage stabilizer and the voltage regulator are chosen according to the current:
1 Continuous working current is smaller than the rated current of the voltage stabilizer or voltage regulator, Better to have a design margin of 20%.
2 The loads start current is smaller than 5 times of rated current of the servo voltage stabilizer with the roller brush and columnar transformer. or 2.5 times the servo voltage stabilizer with a flat brush, 2 times the static voltage stabilizer.
How to choose the capacity of the voltage stabilizer:
Loads Rated current:
Single phase:
Rated current In=Pn/(Vn*cosφ)
Three phase:
Rated current In= Pn/(1.732*Vn*cosφ)
Note:
Pn — Load capacity(kW),
Vn — Rated voltage(V), Tt is Line to Line voltage in three phase system
Cosφ — Power factor.
How to choose the capacity of the voltage stabilizer:
Loads surge current:
Three phase(Motors):
1 Direct start: I(tmax)= In total + In(max)*6
2 Autotransformer start: I(tmax)= In total + In(max)*3
3 Star-Delta start: I(tmax)= In total + In(max)*3
4 Variable Frequency start: I(tmax)= In total + In(max)*2
5 Soft start: I(tmax)= In total + In(max)*3
Note:
I(tmax)— The max start current.
In total — The total rated currents of the loads
In(max)— The max starting current of the motor.
