Electrical Reactor: What are They? (Line Reactors)

What is a Line Reactor? A line reactor (also referred to as an electrical reactor or a choke) is a variable frequency drive (VFD) accessory that consists of a coil of wire that forms a magnetic field as current flows through it. This magnetic field limits the rate of rising of the current, thus redu

How to Test a Shunt Reactor: A Comprehensive Guide

A shunt reactor is defined as a device that absorbs reactive power from a power system and helps regulate the voltage level. Shunt reactors are typically used in high-voltage transmission lines and substations to compensate for the capacitive effect of long cables and overhead lines. Shunt reactors

Switchable Capacitor Bank or Switched Capacitor Bank

It is not always economical to keep a capacitor bank in service throughout the day and night. This is because, a capacitor also provides reactive power to the system as inductor but in opposite direction. Actually capacitive reactive power provided by capacitor neutralizer the inductive reactive pow

Testing of Capacitor Bank

ANSI, IEEE, NEMA or IEC standard is used for testing a power capacitor bank . There are three types of test performed on capacitor banks . They are Design Tests or Type Tests. Production Test or Routine Tests. Field Tests or Pre commissioning Tests. Design Tests or Type Tests of Capacitor Bank When

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
