The lifts Power failure

Now a days people experience power failures in the lift invariably and that is horrifying most of the time. The scenario is like when the power fails there is sudden big jerk you get and the lights are switched off and the lift is stopped and the heart pounds heavily as the elevator is moving up or down so the oxygen level is changing in the heart and suddenly lift stops and there is a heart get sinking feeling, on top of that lights are turned off and darkness in the lift for next 30 seconds is a big vacuum where you don't know whether you will be able to see the life again. Then suddenly lights are switched on and the lift come to the next floor with lot of noise and the door opens. Now the generator starts and lift operates and it straight away take you to the basement and start afresh journey which takes next 10 minutes or more time of your life as it gets reset and has to start from the beginning. This is because the existing technology of ARD which is called Automatic Rescue Device which only starts when the lift is stopped and it activates after 30 seconds to 1 minute and can only take you to the next floor and opens it. After which the generator kicks in and the reset process follows.

ERD- EMERGENCY RESCUE DEVICE

An Emergency Rescue Device (ERD) is an electronic and electrical apparatus that provides emergency power to the elevators with a 3-phase power supply when the input power source or mains power fails. An ERD differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries through a dedicated Power Bank. They come armed in every possible way to deal with getting stuck during a power failure, technical snags, and all other such trouble

FEATURES OF ERD

ERD is equipped with several high-quality features that ensure maximum safety and security for its users. Safe and smooth rides are guaranteed by modern ERD. It is essential to know in detail about the safety features and operating mechanism of this device before installing one.

SOME OF THE SAFETY FEATURES OF ERD
ARE DISCUSSED BELOW

Prevents Damages

Now a days people experience power failures in the lift invariably and that is horrifying most of the time. The scenario is like when the power fails there is sudden big jerk you get and the lights are switched off and the lift is stopped and the heart pounds heavily as the elevator is moving up or down so the oxygen level is changing in the heart and suddenly lift stops and there is a heart get sinking feeling, on top of that lights are turned off and darkness in the lift for next 30 seconds is a big vacuum where you don't know whether you will be able to see the life again.

Protects
life

Another major crisis situation in emergency situations is when people are stuck in closed environs, especially elevators. This creates a fear psychosis through claustrophobia where people feel choked even if there is proper ventilation in the lift. American Journal of Psychology mentions that this can aggravate serious and life-threatening situations for the occupants, especially kids, pregnant women, elderly and disabled people, and a small time-lapse of 30 seconds can lead to unpleasant situations like fainting of people to a serious situation that can trigger cardiac failure.

An ERD-enabled lift eliminates these horrifying situations while providing disaster resilience to the buildings, users, and operators. No Generator or existing ARD system can provide smooth operation of elevators like an ERD during the critical period of a power failure saving lives of people in an economical and environmentally friendly fashion.

UNDERSTANDING LIFT OPERATION

IN-CASE OF POWER OUTAGE
  • Main Supply Cuts
  • ARD (Automatic Rescue Device) takes lift to nearest floor
  • Automatic Genset takes 45 Sec to 1 Min to provide power to the lift
  • ARD Rechecks all the circuit and confirms if everything is Okay, this process takes another 45 Sec.
  • In totality reworking of lift starts only after 1:30 Min to 1:45 min.
  • In-case of manual Genset, operational time will be between 2 mins to 5 mins
UNDERSTANDING LIFT

POWER CIRCUIT WITH ERD

ERD Supersedes ARD as
Lift passengers does not feel any power outage,

lift operates smoothly on battery power. With ERD the switching time is almost zero so the lifts do not stop at any occasion and the generators are not required. Whenever power goes the lifts work smoothly without any jerks and that keeps the lift electronics and electrical systems running without any break.

Since there is no break in the power, the smooth functioning removes the chances of lifts failures.

The power quality supplied by the ERD is better than the power supplied by the Electricity companies as it is pure sine wave power and the frequency is exact 50Hz. The voltage supplied has the high stability compared to the utility supplier.

The power quality supplied by the generator cannot be compared by the ERD as it has a very stable and clean power as it is only catering to the lift load only.

No Generator or existing ARD system can provide smooth operation of elevators like an ERD during the critical period of a power failure saving lives of people in an economical and environmentally-friendly fashion.

ERD IS A
SOLAR ENABLED

ERD it is a green & clean technology which can make it solar enabled system by adding charge controller and solar panels, which can charge the ERD power bank thorough solar energy. We have developed the technology where solar can be added at any stage.

SOLAR FEATURE IN THE ERD

The extra electronic board of charge controller is inserted and that talks to the controller board of the ERD and these two works in a synchronized manner. As when solar is available the battery charging is happening through solar or if solar is less than the charging is happening through the sharing of solar and grid both. But the priority is always through the solar. When the batteries are charged and solar is available then the system switch off the mains and work on the solar and battery power to save the power bill completely. Since the battery is charged through the solar the battery life increases to 20 to 40 percent. Also in this case, the generator may not be required at all because solar power takes care of a long backup time as well.

TAILORMADE
SOLUTION
  • The machine can be designed for small to big lifts up to 500 KVA load.
  • The machine can run on lead-Acid as well as lithium batteries.
  • It can provide a power back-up up to 2 days.
  • It does not require any air conditioner.
  • It has BIS Certification.
  • It’s low on maintenance machine.

ELECTRONIC
CONTROL UNIT

ECU as the name is Electronic Control Unit which is installed inside the lift which gives indication to the people traveling in the lift that lift is working on the Mains power or on the ERD power. Since there is no feeling comes to the passenger travelling in the lift of power outage so it’s important to give the idea to the passenger that lift is working on the emergency backup. So, this ECU has the announcement facility as well so there is a memory card inside the ECU which can be used as a recorder to record the announcement messages in different languages and that can be programmed on the site itself. In case of battery getting low or completely discharged it give the indication along with the announcements to the passenger travelling in the lift. It will save the space as well as cost and maintenance.

CENTRAL
ERD SYSTEM.

We have designed 50 KVA to 500 KVA ERD system which can run 4 to 20 lifts together of different capacities and can be placed in a ground position in the Area which can save the costing, space and maintenance cost. This central unit can be used as a back- up for common lights of the building as well. Since there are no switching time so common areas lights will also keep functioning without any flicker along with the continuous operation of lifts in case of power failure. We have already completed a project of Chintels Paradiso where we have operated 18 lifts with one central ERD system.

We have specially designed two ERD's of 150 KVA & 200 KVA to run the 18 lifts of the capacity of 11.5 KV along with the 20 motors which are working in the complex situation for various other applications.

These ERD's have no switching time so the motors & other load connected to it has no inrush current requirements & every load is working without any switching time so people can’t feel any break in services.

These ERD's can also be designed as per the customer specifications and requirements like common lighting loads, motors or any other common loads required by the cluster of building whether commercial or residential as per the requirement of the individual customer.

REGENERATIVE LIFTS

Regenerative lifts can save electrical energy under certain lift operating speeds and travel distances. For lifts operating at speed greater than 2.5 m/s under light load in an upward direction and heavy load in a downward direction with the designed lift, the energy-saving performance is obvious. Today, most elevator companies are manufacturing premium elevators for high-rise buildings that are highly energy efficient. And Su-vastika also manufacture such premium regenerative lifts. The elevators have improved hardware, control system, and other systems that are not only energyefficient but also more compact, and even generate power that can be used by the facility.
