EFFECT OF STABILIZED VOLTAGE ON EQUIPMENTS

A voltage stabilizer, as the name suggests helps us to have a stabilized the voltage. When there is a high voltage then it makes it to the required level of electrical equipment and vice versa. Stabilized input to the machines helps us to increase the efficiency of machines as well as quality of final product improves.

Now we consider the two cases i.e over voltage and low voltage, in first case i.e in case when the voltage is higher than the voltage at which equipment is designed to operate most effectively. Due to this over voltage problem equipment lifetime will reduced and increases in energy consumption without any improvement in performance. Similarly in second case when the voltage goes on lower side than the required/ designed voltage, due to this problem number of problem will generate in equipment, for example contactors and relays may drop out which will be the reason for interruption in operation of machines.

Your expensive equipment is being subjected to undesirable stress because of improper voltage. Typical ill-effects on some common equipment are illustrated below.

Equipments	Effects of under voltage	Effects of over voltage
UPS Systems	Low Battery Life	Failure
Electronics	Malfunction	Failure
Electron Tubes	10% drop reduces Cathode emission by 40%	5% increase reduces tube life by 50%
Rectifier Loads	At 10 % under voltage, plating rate drops by 20%, charging rate Drops by 25%, welding time increased by 20%	Excessive heat generated, produces poor welds can reduce rectifier life substantially. Plating/deposition may be uncontrolled.
Motors/ Air Conditioning	Overload and uneven heating/ low efficiency.	Overheating
Lamps, Tube lights Heating Elements	Low lux, reduced efficiency.	Higher Failure/ high energy consumption due to over heating
Process Plants	Increase in wastage of finished product, stoppage of production	Uneven quality

Increase Productivity & Product Quality:

If you install POWERWARE Electronic Automatic Voltage Controller, an added advantage is increase in Productivity & quality. This is due to the fact that nuisance equipment breakdowns due to overheating will come under control & production will go on uninterrupted. Additionally, due to a well maintained voltage level, there will be no variations in process parameters leading to consistent quality.

Further efficiency of POWERWARE servo voltage stabilizer is approx. 98.5% as compared to competitors (even IS standard) which specifies only 95%. We give below the calculation to establish the additional potential saving Rs. 3,78,000/- per year recurring, which will accrue to you using our high efficiency 500 KVA servo voltage stabilizer.

1. Min. Guaranteed Eff. of POWERWARE SVS = 98.5 %

2. Eff. of Other Make = 95 %

3. Difference is = 3.5%

4. Rating of the stabilizer = 500 KVA

5. 3.5 % of Rated Capacity = 3.5 % of 500 = 17.5 KVA

6. Total Energy Difference = KVA DIFFERENCE X 12X300 = 63000 Units

7. Cost of These Energy @ 6.00 per unit = Rs.3,78,000

So, We can observe from above that with the help of SVS we can prevent our costly equipments by voltage fluctuations as well as we can get huge saving on our yearly/ monthly energy bills.

SITE INSTRUCTIONS FOR TRANSFORMERS (PART 5)

Sai Electricals — Wed, 26 Aug 2015 06:32:00 +0000

After successful installation it is very important to take care of the various safety measures during operation of transformer. Transformer ageing is very much depends upon various stresses like electrical i.e. loading patterns, surges & spikes, voltage & frequency variations, short circuit forces, over fluxing harmonic, mechanical, chemical and environmental factors which will affect the insulation of transformer and deteriorate the insulation this deterioration will affect the performance of transformer and reliability of equipment got reduced. Besides of theses stresses faults like partial discharge, electrical arcs, or hot spots generally deteriorate the condition of transformer in quick progression. Hence early detection of these faults is very important for saving transformer from any catastrophic failure.

Now a day’s various methods are available with us through which we can monitor and record the real time data for various parameters which are having a great impact on transformer performance, some of the parameters are as follows:

1) Internal Parameters

a) H2 PPM Level

b) Ambient Temperature

c) Oil Temperature

d) Winding Temperature Rise

2) External Parameters

a) Voltage & Current on all three phases.

b) Active/ Reactive Apparent Energy & Power

c) Maximum Demand/ Demand Forecasting

d) Time Bound & Stamped Data for KVAH/KWH/KVAR

With strict monitoring, accurate diagnostics of above parameters the following would be achieved effectively:

• Asset economic loading conditions identification and assessment for maximum practicable operating efficiency.

• Premature failures risk minimization.

• Life estimation and timely asset replacement/ retiring planning.

• Asset life extension by implementing correct operational and cost effective maintenance strategies

• Improvement in the system performance ensuring good reliability as well as plant availability.

• Minimization of the long-term operational cost.

• Cost saving by eliminating the unplanned maintenance.

• Minimizing the outage period.

• Relocation/ retirement planning.

• In time procurement of spare parts to get competitive rates.

• To enhance the overall reliability of the system

• Accurate risk assessment.

For recording and monitoring the real time date for above parameters we can take the help of online condition monitoring system for transformer, the typical schematic diagram is as below:

Above system are available with powerful software and having the various features some of them are as below:

Connectivity

Available through MODBUS, RS 485 & GSM/CDMA (Though Modem)

Inbuilt Software

WHY Meerut is vibrant enough to become a smart city

Sai Electricals — Thu, 16 Jul 2015 10:10:00 +0000

By Girish Kumar

Keeping in view the aspirations of modern citizens, in todays world any city with a populations of 1.5 to 2.0 millions people will require smart city to live a life of Vibrancy. A smart city that is equipped with basic infrastructure to give high quality of life, a clean and sustainable environment through application of some smart solutions. Assured water and electricity supply, sanitation and solid waste management, efficient urban mobility and public transport, robust IT connectivity, e-governance and citizen participation, safety and security of citizens.

Meerut is the second largest city in National Capital region only after Delhi. Meerut could be one of the smart cities of India.

The city Meerut feels pride to stand fifth on the vibrancy index, declared by the US based financial company Morgan Stanley in the 2011 survey done on 200 cities of India. After examining it on their prescribed parameters the company adjudged its position ahead of Delhi and Mumbai in terms of investment and economic growth.

The Walled city Meerut has shown its existence from ancient period of Lord Rama and thereafter Kuru dynasty of Mahabharta which had privilege of having close association with Lord Krishna. The city also has pride of having some of the archeological site like Alamgirpur which existed parallel to Harrapa and Mohanjodaro. It also spearheaded the first war of Independence against British Raj in 1857.

SMART ENVIRONMENT

Besides being second largest city in National Capital Region (NCR) it also spearheaded the green revolution in the region in 1970s turning the region into an ‘agriculture belt’. The bumper crop of Sugarcane and potato year after year has paved the way of setting up many sugar mills and food processing plants in the region.

The trade of frozen meat flourished in the region in past one decade and many of international brands of frozen meat belong to this city which has been earning a good amount of foreign currency for country`s exchequer.

SMART ECONOMY

The city also has earned name in the manufacturing of sports goods especially world`s top cricket brand SG, SS and BDM have originated from this walled city. Engineering industry is another emerging commerce in the city. Known for its fine work of scissors manufacturing it has earned certification of geographic indicator patent in the name of ‘MEERUT SCISSORS’. This for the first time that traditional manufacturing activity has earned GI Patent in India.

Originalspecial taste of ‘Rewari and Gajak’ which is now choice of millions across the globe.

SMART PEOPLE

Education and language play a significant role in the development of a city and Meerut is quite fortunate in the way that even after experiencing brunt of many communal riots in past people of different communities have shown their zeal to live and advance on the path of development together.

City peoples` die hard’ attitude also makes it a fit case to put it in a path of development for better future of their coming generation and country as well.

With more than three dozen engineering colleges and over 70 public schools the city has emerged as hub of education. This has given the city youngsters who are well versed in English language which helps in connecting them with rest of the world and easy access to information on internet. The city also has advantage of having four universities including one agriculture university and two medical colleges.

Its skilled artisans are a major demographic advantage for engineering industry while industrialists and entrepreneurs enjoy a cordial relationship which is evident by the fact that the city has experience no ‘labour unrest’ in past fifteen years.

It is a virgin place for industrial development and 12% of its land is available for industrial use along with the advantage of low cost as compared to other places of NCR. Seeing the potential of development GAILGAS Ltd. has made its elaborate setup in the district in order to provide clean and green piped gas fuel to industries for better development of the area. Food proccesssing industries have advantage of low cost of inputs in terms of fuel as well as agriculture produce.

SMART LIVING

The people and the culture of Meerut has promoted harmony and balance between the science and technology of the modern world we live in and the beauty and purity of the natural world that surrounds us. The city is resource rich in terms of the quality of soil available for growing organic agricultural food as also this becomes possible because of the availability of less contaminated Ganga water.

SMART MOBILITY

In a quest to develop the city as new center of development the city is likely to get share of infrastructure projects of over Rs 20,000 crore in coming years These projects include Meerut Delhi express way, Rapid Rail Transit System, Bulandshahr- Meerut express way, Western Peripheral Expressway, Eastern Peripheral Expressway, Upper Ganga Expressway, Airport, Delhi Mumbai Freight Corridor, Amritsar Howrah freight Corridor etc.

Meerut stands thorough on the five pillars of a smart city which are smart economy, smart people, smart environment, smart mobility and smart living. All that we need is smart governance.
