Three-phase Compensation Controller

Three-phase Compensation Controller is an intelligent device for automatic reactive power compensation, built around a high-speed, high-performance microprocessor core. This sophisticated simultaneously samples 3-phase voltage and 3-phase current signals, offering combined split-phase and common-phase compensation schemes. User-modified control parameters are permanently stored and protected against loss during power failures. Its operation is based on the compound control of capacitor bank switching using fundamental power factor and fundamental reactive power, resulting in stable, oscillation-free performance that is not sensitive to harmonic interference from voltage or current. This makes the ideal for automatic control of reactive power compensation in AC power systems (45Hz-65Hz) below 0.4kV. The technical specifications for this are as follows: Rated Operational Voltage: AC 380V; Rated Operational Current: AC 0.1-5A; Static Output: AC 220V 3A; Dynamic Output: DC 12V 10mA; Rated Operational Frequency: 45-65Hz; Displayed Power Factor: Lagging 0.001 - Leading 0.001; Measured Reactive Power: 0-9999 Kvar; Measured Active Power: 0-9999 KW; Measured Apparent Power: 0-9999 KVA; Under-voltage Protection Value: AC 170V; Sensitivity: 100mA; Display Method: Digital Tube. To ensure the Three-phase Compensation Controller

• 1) Install at an altitude no higher than 2500 meters;
• 2) Maintain an ambient temperature between -25℃ and +50℃;
• 3) Ensure air humidity does not exceed 50% at 40℃ or 90% at 20℃;
• 4) Place in an environment free of corrosive gases, conductive dust, and flammable/explosive substances;
• 5) Choose a mounting site without severe vibration.

is the automatic regulation of capacitor compensation devices within low-voltage distribution systems. Its goal is to adjust the power factor to a user-defined state, thereby increasing power transformer efficiency, reducing line loss, and improving supply voltage quality. When used in conjunction with non-contact switches (such as dynamic regulators and composite switches), this Three-phase Compensation Controller fulfills the need for fast switching to accomplish optimal reactive compensation, particularly in installations that benefit from a mix of common-phase and split-phase compensation strategies.
