EQUALIZER ST: THE ULTIMATE MOTOR START-UP SOLUTION

The EQUALIZER-ST is a real-time, dynamic reactive power compensation system for medium and low voltage drop motor startups that utilizes a proven industrial technology to provide the ultimate motor protection control solution for the challenges relat

Exclusive Technology

• Cost effective fast reactive power compensation

• Improves the power quality of the electrical network

• Designed to limit voltage drop motor startup to local standards

• Transient free switching

• Centralized motor startup solution

THE ELECTRICAL CHALLENGE
A motor start demands very high reactive power for a relatively short period of time.
This demand creates typical reactive currents of 6-7 times the nominal current of the motor; consequently a voltage drop is developed in the local network that is usually not designed to withstand these temporary high currents. This voltage drop can create problems for other loads in the network and, if excessive, can prevent the motor from starting.

The Ultimate Solution
A more cost effective solution than Variable Speed Drives or Variable Frequency Drives. 

• In cases that there is a need to reduce the starting torque as well, EQUALIZER-ST is not used a standalone solution, but rather is combined with a soft starter to provide for the complete requirements of the motor:

• In areas with weak electrical networks, a soft starter may not reduce the voltage drop enough for the motor to start each time.  In this case, a EQUALIZER-ST can be used as a considerably less expensive substitute than a Variable Speed Drive (VSD) or Variable Frequency Drive (VFD)  if speed control is not necessary for a manufacturing process.

• In cases that there are Power Quality problems during the motor start, EQUALIZER-ST can improve the power quality
