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 …
Motor efficiency is important to optimize power consumption. 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 …

Evaporative condenser for refrigeration systems are now becoming popular in refrigeration system due to various benefit, Shell and tube condensers are used to be most widely used condensers for the condensation of high pressure refrigerant of refrigeration system with cooling water. In countries where cooling water is available at above 30 Deg C, there is …
Luminous performance of common light fittings are essential to estimate and optimize lighting load at home, office or industry. Lumen/ watt differs with the type of lamp used. Based on the quality of light and energy requirement right lighting selection will not only improve visibility but also reduce energy cost. Lumen is not only should …
Mechanical vapor recompression system are now becoming popular because of its operational economy, Distillation is one of a common method of separation of solvent from a mixture in a process industry. As we know in distillation process water or other solvents are separated with addition heat to a the temperature of boiling point of solvent. …
