Electrical Protection Units And Systems Introduction to Electrical Protection Systems HV, MV and LV[1] electric installations and equipments are subjected to internal and external faults that can cause serious damages in persons and other equipments. To avoid and to minimize the consequences of those faults protection devices associated to equipments that are able to break electric current are required. For …

INTRODUCTION TO CAPACITOR BANKS, ITS CHARACTERISTICS AND APPLICATIONS By: Manuel Bolotinha DEFINITION OF AND CHARACTERISTICS OF CAPACITORS A capacitor, also known as “condenser” is an electrical element with two electrical conductors separated by an insulator material (dielectric), as shown in Figure 1. Figure 1 – Simplified scheme of a capacitor The electric parameter that defines a capacitor is the “capacitance” …

What is Reactive Power and Why it is Useful?  In recent years, the reactive power control has been the subject of a systematic study as it plays an important role in maintaining a secure voltage profile in a large scale transmission system. Though it is a byproduct of alternating current systems, it is needed for the acceptable functioning of various …

 Advantages of Power factor improvement and Correction: Following are the merits and benefits of improvedPower factor; Increase in efficiency of system and devices Low Voltage Drop Reduction in size of a conductor and cable which reduces cost of the Cooper An Increase in available power Line Losses (Copper Losses) I2R is reduced Appropriate Size of Electrical Machines (Transformer, Generators etc) …

  Causes of low Power Factor The main cause of low Power factor is Inductive Load. As in pure inductive circuit, Current lags 90° from Voltage, this large difference of phase angle between current and voltage causes zero power factor. Basically, all those circuit having Capacitance and inductance (except resonance circuit (or Tune Circuit) where inductive reactance = capacitive reactance …

Methods for Power Factor Improvement The following devices and equipment are used for Power Factor Improvement. Static Capacitor Synchronous Condenser Phase Advancer 1. Static Capacitor We know that most of the industries and power system loads are inductive that take lagging current which decrease the system power factor (See Disadvantages of Low Power factor) . For Power factor improvement purpose, …
