AI Overview
An automatic compensation APF (Active Power Filter) cubicle is a comprehensive, parallel-connected, cabinet-housed solution that dynamically corrects power quality issues in real-time. It mitigates harmonic distortion, corrects power factor, and balances loads by injecting reverse compensation current to cancel out non-linear load harmonics.
Key Features and Capabilities
- Dynamic Compensation: Detects load current using CTs (Current Transformers) and provides instant compensation, typically up to the 50th harmonic order.

What is the purpose of an active harmonic filter?
Active harmonic filters, also called harmonic correction units, are parallel devices that act like a noise cancellation system and inject equal and opposite frequencies to mitigate harmonics. The filters can also provide additional current to correct the power factor.

What is APF in electric meter?
Active power filters (APF) are filters, which can perform the job of harmonic elimination. Active power filters can be used to filter out harmonics in the power system which are significantly below the switching frequency of the filter.

What is an active power filter?
Active filters are also called active power line conditioners, and are able to compensate current and voltage harmonics, reactive power, regulate terminal voltage, suppress flicker, and to improve voltage balance in three-phase systems. All active power filters are developed with pulse width modulated (PWM) converters.
