HOW TO CHOOSE A VOLTAGE STABILIZER?

What's the difference between Roller carbon brush with the Flat carbon brush?

Comparative of the different of Voltage stabilizer:

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.
