Capacitance and Dissipation Factor

A Capacitor is a device which has the capability to store energy in its Electric Field. Therefore we can say that a Capacitor can store charge. There are many types of Capacitor but the most basic Capacitor is Parallel Plate Capacitor. We will consider this basic capacitor for getting idea of basic but important parameters … Read more Capacitance and Dissipation Factor

Dynamic Contact Resistance Measurement, DCRM

First question which strikes in our mind is that why do we need to do DCRM even though we already had Contact Resistance Measurement,CRM? Seems good question and this question will take you to the depth. So, first of all we need to know about the contacts of Circuit Breaker. Basically, a CB has two types … Read more Dynamic Contact Resistance Measurement, DCRM

DC Shunt Motor Charatersitics

Long Shunt and Short Shunt DC Compound Machine: In short shunt DC Compound Machine, shunt filed winding is connected across the Armature whereas in Long shunt connection it is connected across the line terminal. But there is no difference in operating characteristic in two types of machine. DC Shunt Generator Characteristics: There are four basic … Read more DC Shunt Motor Charatersitics
