“Supercapacitor” The Future High Density Energy Storage Device.






SUPERCAPACITOR USED IN UPS 


 Supercapacitors form a new class of electrochemical energy storage device which  play an important role in providing very high electric power boost demanded by critical loads applications. 

The  main Advantage of “Supercapacitor” is that it can be charged within  seconds rather than hours.

discharged as very high pulse current over million recharge cycles. 

Supercapacitor suitable for facilities prone to small or very short Power  Interruptions .


Supercapacitor 



ADVANTAGES :

 

1. Supercapacitor is environment friendly, maintenance free.

2. Efficiency level 98%, can operate at wide temperature range of - 40°C to + 70°C, 

3. It covers life span of 15 years without any quick ageing.

4. Ultra Fast Charging .

5. No Maintenance risks .

6. No Fire Risks .

7. Ultra High Power Density .

8. Small carbon Footprint .

9. Supercapacitor can store Energy 10,000 times more energy than a standard ups capacitor .

10. High cycle efficiency 95%.

DISADVANTAGES:-

1. Back up time is less few minutes .

2. Discharge rate is faster .

3. Doesn't hold constant voltage during discharge .

NOTE :- Thus in the near future the chances of the supercapacitor replacing the battery are remote. However, battery-supercapacitor with electronic controller combine power pack is likely to find use in many low voltage applications.




Battery vs. Supercapacitor




• For decades, battery has been the preferred form of energy storage as it has high energy density (10~100 Wh/kg). 

• However, limited by operating temperature (typically 0°C~40°C) and cycle life (2 years or 500 charge-discharge cycles), battery is neither rugged nor durable enough for industrial applications. 

• Supercapacitor, also called electric double-layer capacitor (EDLC), is an emerging category of capacitor offering 10~100 times more energy density than electrolytic capacitor (1~10 Wh/kg). 

• In addition to its impressive energy density, supercapacitor also has a wide operating temperature range (-40°C~85°C) and long operating life (10 years or 500,000 charge-discharge cycles). 

• These two traits help make it a reliable industrial power backup solution.

• The advantages of supercapacitors are particularly pronounced, with output currents rising to hundreds of amps or even thousands of amps with almost no delay, and fast charging, energy storage in a short period of time, and 50,000 cycle life Do not need care for ten years, so that UPS is truly maintenance-free.

• Sealed lead Acid VRLA batteries continue to dominate the Ups Market , However as costs continue to fall Supercapacitor are quickly becoming viable solutions.

• Supercapacitor suitable for application where short power interruptions and backup time in few minutes , whereas batteries has 60 minutes backup .

• Supercapacitor has wider temperature tolerance suitable for harsher environments , VRLA batteries need to maintain at  25 degree centigrade .

• Batteries are the most common solution to backup power in a Ups but it also acts as weakest link in the system and leading to cause of Power related problems and downtime , Chances of Battery blast and battery open are higher in case of power interruptions .


Supercapacitor are the Energy storage Solutions providing Reliable Backup power for protecting Mission  Critical Applications loads from unplanned Downtime .

ACB Tripping settings

ACB tripping settings   Acb has 6 adjustable tripping settings 1 Long time delay (Tr ) 2 Short time delay( Tsd ) 3 Earth fault delay (Tg) 4 Long time (Ir) 5 Short time (Isd) 6 Earth Fault (Ig) Long time is for maximum overload capacity . Short time is for short circuit current Earth fault is for earth fault current . As per thumb Rule : 1. Long time set at 0.8 means 80% of full load current .Until this level of current  breaker carry without tripping  . Above 0.8 Acb trips. Long time delay causes the breaker to wait for certain time to allow heavy temporary inrush currents to pass away. Generally long time delay is set at  4 Sec. 2. Short time set at 0.6 means  60% of full load current . It determines the Amount of Current the Breaker will carry for short time period.  Generally short time delay set at 0.2 sec. 3. Earth Fault set at 0.3 or 30% of  fault current . It controls the amount of Ground Fault current that will caus...

conservator tank oil level (Mog) The MOG  (Magnetic Oil Gauge)  is a device by which we can supervise the level of oil inside the tank or conservator of power transformer and also gives us an alert low oil level indication .  A decrease in level of Transformer oil in Conservator is an indication of leak and therefore MOG level is an important parameter to be monitored. Practically under running condition oil level remains at 3/4 th level.

HIGHER EFFICIENCY MOTORS (HEM)

Super premium Efficiency (IE4) motors  IE4 MOTOR The higher price of the IE4 motors is due to :  1. the use of high-quality materials and optimization of assembly and design of these motors to achieve higher efficiencies upto 97% . 2.  Large-diameter copper wires and more quantity of aluminum are used in rotors of these motors to reduce the resistance losses.  3. An optimized cooling fan is also used to reduce the winding losses. 4. use of advanced technologies like diecast copper rotors enables achieving higher efficiencies in the same frame size. The use of the high-quality, expensive materials increases the overall cost of this type of motors. adoption of energy efficient technologies to reduce their energy consumption and carbon emission. 5. Stator and Rotor I2R losses: Stator and Rotor I²R losses appear when heat is generated by resistance from current flowing in the stator windings, rotor conductor bars. These are major losses, typically account for...
