| 77 | Power Factor Controller Set up should be designed to study the working principle of Power Factor control system in 3 phases Motor Load set up. It should consist ofA. APFC Relay with CapacitorB. 3 Phase 3HP Motor LoadC. Panel with meter & Autotransformer(A). APFC (Automatic Power Factor Control) Relay with CapacitorAPFC Relay for Power Factor Correction in Low Voltage applications should measures the actual power factor and Connect or disconnects capacitors to achieve a target power factor. The single phase electronic measuring system should detect the reactive and active component of the network through the current and voltage path. From this it should calculate the phase shift between current and voltage and compares this with the set target power factor.Specification• Micro controller based design• Effective PF control for balanced loads• 6 or 8 stage option• Auto (or) Manual operation• Front panel digital display for PF• Alarms indication• Voltage Input 415V Ac ± 20%, 50 Hz• Current Input 5A / 1A from CT secondary (Field selectable)• Desired PF setting 0.8 lag to 0.8 lead• Capacitor Bank selection 6 stage Capacitor• Necessary inbuilt 3 phase Capacitor bank with different tapping (6 stage) should provided(B). 3 Phase Motor Load 3Ø AC Motor with load set upType 3Ø squirrel cage induction MotorType 3Ø squirrel cage induction MotorPower 3 HPVoltage 3Ø, 415VACSpeed 1440 RPM Feedback Sensor Proximity sensorLoading Spring balance loadingSpring Balance Loading• One number Brake DRUM with spring balance set up should coupled with the above motor• Two numbers of dial indication (0-50KG) for Load measurement in Kg• All should mounted on a powder coated mechanical set up(C) Panel with meter• One number powder coated panel with mimic diagram should printed on front panel• APFC Relay should fixed on the panel with necessary termination for external connection• Necessary MCB, Switch & indicators should provided.• Banana terminals for 3 Phase AC input & Load Output• One number of 3 phase Autotransformer should provided in panel for Unbalance supply simulation.
