Location of Shunt Capacitors

The power factor improver capacitor can be installed at system bus, distribution point and at load itself. But decision should be taken in view of expenditure and utility. In certain loads mainly in industrial load, the entire load is switch ON or OFF based on need. In such cases it is recommended t

Types of Capacitor Bank

Unit of a capacitor bank is normally called capacitor unit. The capacitor units are manufactured as single phase unit. These single phase units are connected in star or delta to farm a complete 3 phase capacitor bank. Although some rare manufacturers 3 phase capacitor unit but normally available cap

Specifications or Rating of Power Capacitor Bank

A capacitor bank has to go through different abnormal system conditions, during its life span. To with stand these abnormalities at optimum manufacturing cost, the capacitor banks are rated with following allowable parameters. A capacitor bank should continue its service with in the following limits

Shunt Capacitor: What is it? (Compensation & Diagram)

What is a Shunt Capacitor? A capacitor bank is very essential equipment of an electrical power system . The power required to run all the electrical appliances is the load as useful power is active power. The active power is expressed in kW or MW. The maximum load connected to the electrical power s

Synchronous Condenser

Like capacitor bank , we can use an overexcited synchronous motor to improve the poor power factor of a power system . The main advantage of using synchronous motor is that the improvement of power factor is smooth. When a synchronous motor runs with over-excitation, it draws leading current from th

Capacitor Bank: Definition, Uses and Benefits

A capacitor bank is a group of several capacitors of the same rating that are connected in series or parallel to store electrical energy in an electric power system . Capacitors are devices that can store electric charge by creating an electric field between two metal plates separated by an insulati

Measurement of Insulation Resistance

We define insulation resistance as the ratio of applied direct voltage across an insulation to the corresponding current through it. Mesaurement of inslation resistance is quite important. We normally take the reading of the measurement at a certain time after application of test voltage . The stand

Electrical Insulator Testing | Cause of Insulator failure

To ensure the desired performance of an electrical insulator , that is for avoiding unwanted insulator failure , each insulator has to undergo numbers of insulator test . Before going through testing of insulator we will try to understand different causes of insulator failure . Because insulator tes

What is an Electrical Insulator? An electrical insulator (also referred to as an insulator) is used in an electrical system to prevent unwanted flow of current to the earth from its supporting points. The insulator plays a vital role in the electrical system. An electrical insulator is a very high r

Dielectric Properties of Insulating Materials (Formula & Constant)

We can first go through the description of dielectric materials . It actually does not conduct electricity. They are insulators having very low electrical conductivity . So we have to know the difference between dielectric material and insulating material. The difference is that insulators block the
