High Performance Harmonic Protector
Schematic for Working Principle
HIGH PERFORMANCE HARMONIC PROTECTORS
Adopting Advanced Digital Signal Processing TechnologyTo Offset Harmonic Current
It eliminates the harmonic at power side, real-time detects the waveforms generated by nonlinear load, separates harmonic part, then injects its reverse current into power grid through trigger of IGBT inverter to realize function of filtering harmonic.
Working Principle
High performance harmonic protector detects load current through current transformer, and extracts harmonic components in load current, and makes inverter generate a harmonic current equal to load harmonic current and opposite in direction, then inject it into power grid to achieve the aim of filtering.
Product Features
- Filtering harmonic, purifying system, very fast response speed
- Filter multiple harmonics can also filter specific order harmonic
- Provide capacitive and inductive current correction
- Can use multiple sets in parallel
- Overcoming high frequency interference caused by harmonic pollution
- Reasonable structure design, simple wiring, convenient installation
Application Occasions
- Place where a large number of computers, switches are used, for example: stock exchange, commercial office building.
- Places where there are a lot of harmonic current and frequently changing loads, such as: stadium, subway, etc.
- Occasions where there are heavy loads, large harmonic current
- Precision machining industry, for example: film industry, pharmaceutical
- Other industries where there are a lot of rectifier equipment
