Low Capacitance Harmonic Filter with Bluetooth® Technology
HGL with PQconnect is the first intelligent low capacitance filter to offer harmonic mitigation that automatically detects excess kVAR while also allowing remote monitoring and control.
- Offers the lowest kVAR per horse power filter on the market, allowing for superior generator compatibility
- Ensures IEEE-519 2014 compliance with true 100ka SCCR rated filters
The HGL with PQconnect offers 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. Due to the reduction of reactive power, the HGL allows for lower power, cost-efficient generators to be used. Bluetooth technology allows easy access to your passive filter data via an Android app.
The HGL also features components designed specifically for oil and gas field applications, to handle the additional electrical stress. These units are available in Type 3R enclosures and are designed for cyclical loads, with HP ranges from 20 to 800 HP.

- Sensitive equipment failure
- Poor power factor
HGL with PQconnect Advantages
The HGL harmonic filter is a field-proven low capacitance harmonic filter designed to meet your specific industry requirements. This filter not only limits current distortion to less than 5% TDD, it also improves true power factor. Multiple package options will allow you to choose the right filter configuration for the application.
With the addition of PQconnect, the HGL filter features:
Generator Compatibility with Intelligence
The HGL with PQconnect is the most generator compatible harmonic filter with intelligence. The filter autonomously controls its tuning circuit contactor based on your input system to ensure worry-free operations for generator-based systems.
Industrial Strength
The HGL with PQconnect is built in the USA, using high quality components. It delivers the best in class performance under the harshest conditions and in the most challenging applications.
Industrial Communications
The PQconnect provides data monitoring and status of the filter to your SCADA system. The filter will communicate informational alerts to ensure your system stays running and resolves power quality issues. PQconnect can communicate via Modbus RTU over RS485 or EtherNet/IP.
Filter Status Detections
With PQconnect, you can receive alerts before problems occur. Users will be notified if issues were to arise, including on the components of your filter. This will prevent unnecessary downtime and will alert the user when capacitors are nearing end of life.
