Plant & Machinery L&T DISPLAY HIGHLIGHTS AT ELECRAMA 2012 SAFER PRODUCTS FOR A BETTER TOMORROW A home, office or a workshop should be like sanctuary and a safe haven. You can ensure that you and your loved ones remain out of harm's way in the precincts of your homestead and workplace. Beside human safety, equipment protection is equally critical. To avoid all kinds of accidents you have to make it an accident-proof dwelling. It's really simple if you observe specific steps to keep mishaps at bay and install shock proof products and solutions from reputed players. At Elecrama 2012, L&T Electrical & Automation (E&A) has displayed and launched a whole new set of products & solutions for various domestic and industrial electrical and automation needs with in– built safety features that superior to the conventional devices. So, before you buy an apartment, you should now check with the developer if the elevators in the buildings are fitted with a Drive that comes with unique features and functions ensuring safe and smooth ride. L&Ts L1000 Drive has the 'Automatic Rescue' function that enables safe parking of the elevator at the nearest floor in case of power failure. A futuristic diagnostic utility keeps a tab on performance life of quality components of the Drive for preventive maintenance. L&Ts Human Machine Interface (HMI) offers highly reliable hardware promoting safe & long lasting operator interface performance. MCOMP, a relay, is L&T's answer to the world of motor protection. This relay gives protection to all motor, from lower to highest ratings. It is the first relay to be certified by Profibus International. This will help L&T consolidate its leadership in the Indian technology race. L&T's highly intelligent & robust fire detection systems immediately spring into action in an unfortunate incident of fire and the 100 per cent redundancy feature of the panels ensure that the system is always functional, even in case of multiple hardware failures. The panel is supplied with battery backup of 72 hours. Integrated short circuit isolator on each device ensures failure of any device does not affect the functioning of other devices. The vandal resistant video surveillance models are also apt for installation at public places. L&T has developed a whole lot of new products and applications for the industrial and infrastructure segments as well. For personnel safety, MO contactors have been designed with safety shrouds on power terminals, since it can be a potential hazard if left exposed. The RTO overload relay is equipped with tamper proof settings to protect against wrong or unintended settings. Its MOC Capacitor Duty Contactors come with enclosed resistor assembly for enhanced product safety to prevent burning of the contactors in case of any loose terminations. Going beyond the prescribed product standards, L&Ts U-Power Omega ACB has several in-built features to ensure operator & equipment safety. The arc chute interlock ensures operator safety; the mechanical & electrical anti pumping feature prevents the breaker from auto closure if the breaker has tripped under fault and also reduces the electromechanical stress on the system (the breaker mechanism is designed in such a way that if the arc chutes are not placed in its position the breaker will not close); raking interlock; true RTC and locking arrangements. In the T-era Range, operator safety and board reliability are ensured with its compact design which saves space, total closed door operation, racking of the breaker without door opening, an arc resistant design and clearances higher than those required by standards. It is also built to simplify communications solutions and provide user customization through fully interchangeable modules. A distinct vertical earth bar of full length is provided in each front and IP3X separation of vertical busbars post module removal is an added feature. Dsine range of MCCBs with next generation Matrix protection and control units, fire proof plastics are used to ensure that fire does not get propagated in the event of an accident. Finger proofing of terminals and double insulated accessories enhances safety and locks and interlocks for operator safety. The 11 KV AIS 36 KV GIS provide total protection against arc faults in high voltages and the FCOMP feeder protection relay satisfies the most stringent needs in feeder protection in industrial setups. A new range of Automatic Power Factor Control (APFC) panels are designed with optimal amount of duration to withstand harmonics overload current, which ensures prevention of harmonics amplification and resonance. L& T E&A has also launched solutions to support the power sector's efforts to exploit the vastly untapped potential of alternate renewable solar energy. Its comprehensive, fully integrated modular 21
