Harmonics play a significant role in the world of electrical power systems. They are integer multiples of the fundamental frequency and are responsible for shaping the quality of electrical waveforms. The fundamental frequency from the power grid is mostly 50Hz and 60Hz, also known as the ‘1st Harmonic.’ As we move up the harmonic series, […]

Current Transformers (CTs) are commonly utilized for current monitoring purposes or for the conversion of primary current to reduced secondary current, which can be utilized by meters, relays, control equipment, and other instruments. CTs, which function as current transformers, reducing the magnitude of the measured current to a standardized value that is safely compatible with

In modern factories, capacitor banks are not the most effective solution for Power factor improvement !! Â This study was carried out to identify and rectify, what initially seemed to be a malfunction of a powerfactor correction capacitor panel (PFCCP) (Power factor improvement). However during the study it was identified that the problem was not
A transformer’s primary and secondary windings have resistance and reactance, collectively referred to as impedance. The impedance opposes the flow of current when the transformer is connected to an AC power supply, causing a voltage drop across the windings. When an AC voltage is applied to the primary winding, it generates a magnetic flux. However,

If we consider a facility where considerable reactive load variations are taking place, capacitor banks connected to that installation has to follow up a dynamic operation with its steps since it has to respond to the dynamic reactive load variation very fast and provide the required KVAR to the system to maintain its power factor
Do the harmonics in your distribution system is a potential threat for your capacitor bank? Yes. When a capacitor bank is installed in a harmonic rich environment, they create a low impedance path and magnify the magnitude of current and voltage harmonics in a system resulting in parallel resonant effect. With this resonant phenomena, the

As the name suggests, Surge Protective Devices are used to protect the Electrical Installations from transient over voltages what we called as voltage surges. These transient over voltages are defined as electrical surges lasts for short duration occurred due to sudden release of energy which is previously stored or induced either naturally occurring or man-made.

There is a norm that since capacitor banks are static type electrical equipment, regular maintenance is not required. But capacitors need to be monitored and maintained regularly. The unawareness and the negligence of the users may leads to reduce the life expectancy or failures of the capacitors which would cause an ultimate loss for your

Electricity distribution is the final stage in the delivery of electricity from generating power plants to end users. A distribution system’s network carries electricity from the transmission system and delivers its load centers. It is the most visible part of the power supply chain, and as such the most exposed to the critical observation of

Abstract: This paper presents an overview of the electric arc faults which can be originated in electrical devices such as electrical panel boards. There are many codes and standards which are used to define the constraints that an installation should maintained to minimize the severity, frequency and harmfulness of an electrical arc fault. For an
