Harmonics that occur as a result of voltage and current waves distorting away from the sinus form in industrial facilities may damage the electrical equipment in the facility due to shortening of capacitor life in compensation panels, overheating and efficiency reduction in motors, insulation deterioration in transformers, and excessive voltage and current they create in the network. Harmonic distortion and the resulting power quality problems made it necessary to use harmonic filter reactors in industrial facilities.
Inductive Load Reactors
They are used to nullify the effect of capacitive reactive energy or for inductive load in test setups.
Harmonic Filter Reactor
It is used to correct harmonics and power factors occurring in facilities.
Input Protection Reactor
The input protection reactor used at the input of motor circuits and driver systems prevents sine wave distortions in the network.
Output Protection Reactor
These reactors, used at the output of drive systems, are used to protect the motors.
Reasons for harmonics occurrence
Compensation Panels
Motor Drivers
Speed Control Devices
LED Fittings
Computers
Uninterruptible Power Supplies (UPS)
Rectifiers
Welding Machines
Industrial Furnaces
Some problems caused by harmonics
Malfunction of electronic cards, computers, and devices;
Voltage rise;
Problems in elevator control cards;
Heating of cables;
Irregular operation and heating of electromagnetic devices;
Compensation fuses opening;
Breakers and switches opening without reason;
Abnormal operations of the automation system;
Punctures in cables due to high voltage;
Power losses and explosions in power capacitors;
Vibration in machines in facilities;
By using reactors:
- Excessive currents are prevented due to harmonic resonance.
- The lifespan of capacitors is extended.
- Cable heating is eliminated.
- Faults caused by harmonics in the network on sensitive devices are prevented.
- Quality data assurance is ensured in case of data errors.
- Engine heating problems are eliminated.
