Case Studies and Stories
Reducing Costs with ESA and MCA™ Technology
More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..

What is Dissipation Factor?
Dissipation Factor is an electrical test helps defi ne the overall condition of an insulating material. A di-electric material is a material which is a poor conductor of electricity but an effi cient supporter of an electrostatic field. When an electrical insulating material is subjected to an electrostatic fi eld, opposing electric charges in di-electric material form di-poles
