Low Voltage Panels
AUTO SYNCHRONISING & LOAD-SHARING
Mega Electrical is one of the best Automatic DG Set Synchronising and Load-sharing Panel manufacturers & suppliers in India. All our panels fully comply with all regulatory requirements and are fully tested. Every panel is custom designed and built to customer specifications.
Applications
- Transformer and Multiple DG Distribution.
- Sub- distribution for the above.
Features
Used for Synchronization and Automatic Load Sharing between multiple Power sources/lines like Mains, Grid, Generators. This is Microprocessor based Controller with a high degree of customization, which can be configured to meet the Clients requirements. Synchronizing as well as precise KW Load sharing with in-built protections for engine, generators and mains like over current, overload, earth fault, Reverse power, over/under voltage, low oil pressure, high water temp, over speed and SYNC CHECK, AMF, etc. Also GRID paralleling is possible with import / export control PLC for system logic configurable input / output as per requirement.
Unique Features
- Manual Synchronizing of Diesel Generator Sets.
- Protection & Control of Diesel Generator Sets.
- Annunciation & fault indication.
- Automatic Control of Diesel Generator Sets incorporating following functions:
Unique Advantages
- The total programme is based on load in KW. Hence the actual sharing, starting, stopping & transfers are actual load dependent & not on any other unrealistic parameter like voltage, current. Etc.
- Changing of scheme becomes very easy because of changes are made through software and module only. There is no changing of wires, adding of components like relays, contactors, which is very time consuming, cumbersome & requiring additional space.
- Along with KW sharing, KVAr sharing & PF sharing is very accurate, because of DG Syncro. And load management programming. There is no possibility of any unequal sharing as regards KW, KVAr & PF.
- For any type of load addition or reduction, manual intervention as regards D.G. set operation is not required. However, in case of emergency manual override is possible.
- Special programmers using Real Time Clock (RTC) are possible. With this facility, along with KW dependent programs; day, date & time dependent programmers are possible.
- Because of KW dependent load sharing, optimum utilization of D.G. sets are possible. This increases D.G. sets efficiency & saves lot of fuel.
- D. G. sets are always tried to run with 80% to 90% load factor, where we get maximum efficiency. This is easily possible with our system.
- Because of PLC based DG module, hardware like relays, contactors, wiring etc is reduced drastically. This reduces fault points & increases the MTBF of the system.
