Harmonic Filters

The AHC Range of Active Harmonic Conditioners from Power Efficient Systems are available for a number of applications and are specifically designed to reduce the Current & Voltage distortion due to Harmonics.

Harmonics are generated in the main by non-liner loads (Thyristor Drives - Variable Speed Drives etc.) on a consumers installation, leading to a number of undesirable effects as detailed below:

• Nuisance Tripping of circuits
• Unexplained failures of electronic circuits & associated drives.
• Malfunction of control systems.
• Overload of capacitors and associated systems.
• Excessive heating of transformer, switchgear and cables.
• High neutral currents leading to neutral "Burn Out"
• Interference of computer systems and telecommunications.

PES offer a complete solution to harmonic problems from the investigation of harmonic interference, identification, design, manufacture and installation of a purpose built filter.

Sized correctly for the application, Active Harmonic Conditioners from Power Efficient Systems can remove all the aforementioned concerns and ensure compliance with the required standards for connection to an electrical utility supply. Commonly known as G5/4-1.
