Harmonics caused by variable frequency drives can cause many issues within your facility, including circuit breaker tripping, capacitor bank failures, motor failures, blown fuses and cable insulation failures. TCI products can mitigate these harmonics to improve power quality and provide motor protection.
The HGA filter is an elite system-applied harmonic filter that minimizes harmonics to less than 5% total demand distortion (TDD) at the point of common coupling. By injecting a counter-current, the active filter cancels out harmonics and synchronizes the current and voltage waveforms while improving power factor to near unity.
The HGP with PQconnect filter is a drive applied passive harmonic filter that limits current distortion to less than 5% at low loads. The filter provides connectivity to monitor power quality and control the filter using Modbus RTU or Bluetooth technology.
The HGL with PQconnect is the first intelligent low capacitance filter to offer harmonic mitigation while providing less capacitance to the system. It features generator compatibility with intelligence, eliminating any worry over leading power factor or excess kVARs interfering with your generator.
KDR Input Line Reactors are the first defense in mitigating harmonics. KDR line reactors help to protect 6-pulse rectifiers and power conversion devices such as variable frequency drives (VFDs). When used in conjunction with a VFD, a KDR line reactor can help reduce harmonics and protect the drive from harmful voltage spikes. KDR line reactors are recommended on the input of each VFD in multiple drive applications.
