Automatic Power Factor Correction System:
Features:-
In Life Line Series P.F. Compensation System the power range goes from 50 kvar to 1000 kvar. They are designed for medium to large load networks. They are highly reliable, cost effective solution for maintaining high network power factor.
They are ultimate solution for compensation of unbalanced loads. The compensation is released by measuring the reactive power of the system, through 3 CTs from all 3 phases. This makes it best suited even for most unbalanced loads apart from balanced loads.
They come equipped with following outstanding features:
- Incomer TP MCCB / ACB as per rating.
- Micro processor based Neptune Phasetrac range of 3 phase P.F. Controller with inbuilt Load Analyzer.
- Inbuilt 3 Phase Energy Analyzer with Data Logger
- Modular floor mounting system
- Side/front louvers with Axial Flow/ Centrifugal Fan & Thermostat.
- Heavy Duty specially designed Neptune Capacitor Duty Contactors with high thermal current withstand capacity.
- MCBs for control protection
- Auto/Manual selection through Sel. Switch
- HRC Fuses/MCCB-35kA (optional) for backup protection of capacitor banks.
- High electrolytic grade Aluminium Busbar installed on TP supports.
- Discharge resistors (MOR)
- Standard One year warranty with NSL-10 Capacitor or three Year warranty with Long Life LL-10 Mono16 Capacitors.
- Powder Coated- RAL 7035 / Neptune Blue, structure finish.
- Bottom entry system available with option of front glass.
Control Module with Data Logger
- Measurement of A, V, PF, Cosφ, W, VAR, VA (ΣW, ΣVA, Σvar etc.)
- Sense 1% of load current.
- Auto/Manual mode selection with indicator light.
- Automatic calculation of C/k value.
- Program entry for targeted Cosφ, value.
- Number of capacitor steps are user definable.
- The consequent switching time between capacitor steps is adjustable from 2 to 50 sec.
- C+/NORMAL/C- condition lights indicate actual system state.
- Over Voltage, Insufficient Compensation, Over Compensation state, alarm indicator lights with output contact.
- Adjustable programmable Over Voltage protection for capacitor banks.
- Micro Controller based digital design complying with international standards.
- Flush mounting with rear panel connectors.
- Designed to use with Current T/F (.../5A).
Data Logger Module with Energy Analyzer
Energy Analyzer with Data Logger is having facility to record and display all the 3 Phase parameters of Mains where PFC system is connected. The recording shall be carried out in inbuilt data Logger. It is possible to log the data with adjustable time difference of 1 min. to 24 hours. Same way it is possible to display (optional) all the electric parameters pertaining to PFC system in Control module. The parameters for PFC panel can also be logged in same way. The Energy Analyzer is having real time clock and date. The 3 phase 32 parameters for Mains and PFC systems are available with logging facility to know working efficiency of complete system.
