PMI Electronic pf Corrector Systems (LV applications) provide thyristor based fast correction with 20 msec response time. The uniqueness of PMI Electronic pf Corrector Systems is that there is real ZERO CURRENT switching which is made through 6 thyristor – Diode modules positioned at 6 arms with binary logic, which means 64-step capacitive correction, unlike popular switching techniques which uses slow and deficient mechanical contactors. At each arm, also harmonic filters, connected serial to capacitors are used, which not only limit the current going to capacitors but also suppress the system harmonics at 189 Hz perfectly, the result being that the capacitor life is extended up to its full life time almost without replacement. Because we use semiconductor-switching as opposed to contactor-switching, there is increased reliability. Response speed is 20 msec which is well suited for fast changing, tough loads.
- Electronic PF Corrector based on Thyristor – Diode switching topology for real zero current switching that ensures no voltage fluctuation, no current peaks, no dangerous transients and line pollution during capacitor switching
- Increased capacitor life with zero current switching, no switching stress on components
- Response time is 20 msec. for fast changing loads.
- Each phase controlled independently enabling the device to handle unbalanced loads at optimum level.
- 32 step or 64 step capacitive and 2 step inductive sensitivity correction
- Semiconductor switching increases reliability.
- Periodic test of capacitors and semiconductors gives prior failure detection.
- Modular construction and easy service.
- Remote communication supervision and monitoring.
- Parallel operation with old compensation system to improve total performance.
- Easy construction with standard current transformer.
- Energy saving with unbalanced loads.
- Solves current harmonics with harmonic filters.
- EKM Series solution for unbalanced loads
- Series inductors for damping PFC capacitors
