This Version Of 66 XX Series Displays All Parameters Such As Power Factor, Shortfall KVAR Excess KVAR , Voltage, Current And THD All At A Time. By Selection, It Displays % Harmonic From 3rd To 13th And Capacitor Values. It Has Built In Facility To Cut-off The Capacitors In Case Of Harmonic Overload. It Has Password Protected Settings. It’s Built-in TEST Mode Enables To Test The Panel Without CT Current. Auto As Well As Manual Mode Of Operation Are Available In This Relay.
This Advance Version In 66 Series With Small Volume And Light Weight, Displays All Parameters Like System Power Factor Voltage, Current, System KVA, System KVAr, System KW, Shortfall KVAr, THD. It Works On Smart Switching Algorithm Where A Number Of Capacitors Can Be Turned ON Or OFF Instantaneously Used On The Capacitive KVAr Requirement. It Also Displays Harmonics From 3rd To 13th. It Has Capability To Auto-identify The Capacitor Values. All The Settings Are Password Protected. It Has In-built Capacitor Protection System In Case Of Harmonic Overload And Over-voltage. With In-built TEST Mode, The Panel Can Be Tested Without CT Current.
Certain Elctricals Loads Such As Motors Found In Heavy Machinneries ,can Cause The Electrical System To Be Highly Inductive. This Result In Poor Power Factor . Poor Power Factor Means Higher Energy Losses Which Ultimately Get Converted Into Large Electricity Chrges.
A Simple Solution To This Problem Is To Balance This Inductive Load With Equivalent Capacitive Load . Tis Is Achieved By Connecting Or Disconnecting The Capacitors To Or From The System. Manual Switching Of These Capacitors Is Not Possible In Case Of Rapidly Fluctuating Loads . So Even In An Environment Of Rapidly Fluctuating Loads To Achieve The Required Power Factor One May Need An Automatic Power Factor Control Device, Called Automatic Power Factor Controller, To Connect And Disconnect These Capacitors.
66 XX E3 Controller Is An Automatic Power Factor Controller Used To Control The Power Factor Of The System . It Can Sense The Powre Factor Of Each Individual Phase In The Three Phase System And Can Switch The Capacitors According To The Requirement.
This Is An Advance Version In 55 Series With Small Volume And Light Weight. With A Four Segment LED Display, The Relay Displays Parameters Like System Power Factor, System KVA, System KW, System KVAr And Shortfall KVAr. It Has An Intelligent KVAr Based Switching Algorithm. It Has Capability To Auto-identify The Capacitor Values. With In-built TEST Mode, The Panel Can Be Tested Without CT Current.
This 55 Series Version Uses Microcontroller Technology But With Necessary And Sufficient Features. The Main Feature Is Two Point Setting To Avoid Hunting At Site By User Convenience Which Eliminates Calculations And Setting Of C/K. The Switching Sequence Is In "First In First Out" I.e. FIFO Manner. It Is Very Easy To Install And Its Bright 4-digit 7-segment Display Makes It Readable From Distance.
This 55 Series Version Is Similar To 55 Series Model Of APFC In All Respects Except The Display, The Price And The Size Of The Controller. It Uses 2-digit 7-segment Bright Display For Power Factor Indication. Two Separate LEDs Are Used To Give LEAD/LAG Indication. It Is Smaller And Lighter In Weight Than The Regular 55 Series Model. This Low Cost Version Is Very Popular For Smaller Automatic Power Factor Correction Systems.
Power Kitz Controller Controls The Capacitor Switching With A ‘best Fit Algorithm’. First The Accurate Power Factor Is Computed With Four Quadrant Power Factor Measurement Method. Considering The Target Power Factor And Current Power Factor, Required Capacitive KVAR Is Computed. From All The Available Capacitors (capacitor Recently Turned OFF Are Not Considered As They Are Discharging), The Best Combination Is Computed And Switched ON.
This Mode Of Operation Ensures The Best Use Of All The Capacitors To Achieve The Power Factor Which Is Nearest To The Target Power Factor.
