HVLS stands for High volume low speed, HVLS fans are large diameter fans above 7 feet in diameter normally used for cooling or air circulation over large spaces. These Ceiling fans majorly finds application for large area like auditorium, indoor stadium, railway station, airport, public places, School, cafeteria, animal cooling etc Ceiling fans produces column …
Ceiling fans are most common household appliance after lighting, considering the power consumption in summer it has significant energy contribution for middle and lower middle class people. The power consumption in fans should not be ignored while considering energy planning. To promote energy efficiency in fans, Bureau of energy efficiency (BEE) in India has included …
Development of a country depends on some certain basic infrastructure pillars and one of those is the availability of quality and reliable power in the country. The country needs 24×7 continuous electricity supply to all customers, as well as consistency in sector service and customer participation. After the 2003 Electricity Act was enacted, Indian power …
Transformer efficiency is one of the areas which may help in reducing energy cost, Transformers are one of the most energy efficient equipment and its efficiency can go upto 99%,if operated in the best efficiency area. In transformers efficiency loss is subject to the loading of the transformer. Total loss LT can be easily calculated by LT = …
In general Transformers are classified in two categories,Power transformer and Distribution transformer. As name suggest power transformers are used for network of higher voltage for power supplies say 400KV, 200KV, 110KV, 66KV, 33KV while Distribution transformers are used for lower voltage distribution network say 11KV, 6.6KV, 3.3KV,420V,230V. The efficiency of transformer is typically between 94 …
In Industrial electrical system, Major load is resistive and inductive. Resistive loads are for heating application. In case of resistive Load V= I X R or Power (KW) = V X I Indicative loads are induction motors, induction furnaces, transformers etc, Inductive load requires two kind of powers:- Active Power ( working power) KW Reactive …
The standard defines four IE (International Efficiency) efficiency classes for single speed electric motors that are rated according to IEC 60034-1 or IEC 60079-0 (explosive atmospheres) and designed for operation on sinusoidal voltage. Super-Premium efficiency IE4 Premium efficiency IE3 High Efficiency IE2 Standard Efficiency IE1 The coverage of the new standard includes: Single speed electric …
