Industry leading performance with remote connectivity and intelligent control.

​

Nonlinear loads, such as Variable Frequency Drives and UPS systems, reduce energy costs and provide system efficiencies. However, they also create harmonic distortion, also known as current distortion or line distortion. When present in the voltage and current of an electric power system, harmonics are considered undesirable distortion which can adversely affect power system infrastructure and loads.

​

The HSD HarmonicShield with PQconnect offers industry leading 5% THID Total Harmonic Current Distortion (THID) performance even at light loads and under the harshest of environments. The optional contactor allows the tuning circuit to be disconnected at light loads to avoid leading power factor problems. Natural convection cooling means no moving parts. The HSD with PQconnect offers the performance needed to meet the most stringent requirements of IEEE-519-2014. The HSD with PQconnect is equipped with ModbusRTU communications and intelligent contactor control to ensure seamless harmonic mitigation or Power Factor control. A lug kit option accommodates oversized cabling if needed. All of this is backed up by TCI’s 3-year warranty, which means you will have many years of hassle free operation.
