Sine Wave filter Application case in Petrochemical Company.
Solving the motor overheating problem caused by the long cable between inverter and motor.
Sine Wave Filters convert the PWM output signal of motor drives into a smooth sine wave with low residual;
Reduce the resonance phenomenon caused by distributed capacitance and inductance of the long cable(longer than 50 meters);
Eliminate the excessive motor voltage caused by high dv/dt,
Reduce noise of motor by filter application;
Prolong motor life;
Protecting the motor insulation;
Increase transmission distance;
With the application of this filter, normal motor can replace variable frequency motor.
Applications:
Ventilators,conveyors,Pumps
HVAC installations, Compressors
Elevators ,Cranes , wind power,UPS,EPS
Motor drive with long cable
Motor drive with multiple motors in parallel
Medium voltage applications(deployed in front of the step-up transformer)
