What is transformer impedance?
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. […]
Temperature Monitoring Inside Electrical Switchboards.
Switchgear panels are used to control, protect and isolate electrical equipment, and high temperatures inside these panels can indicate a fault or failure. During the functioning stage, overheating conditions in electrical switchboards can occur due to some reasons such as overloaded circuits, unbalanced loads, and loose connections, which can reduce the lifespan of equipment and […]

Understanding IK Testing:
Ensuring Mechanical Impact Protection for Electrical Switchboards Introduction: Electrical switchboards are vital components of electrical systems, serving as the nerve center for power distribution. Ensuring their safety and reliability is of paramount importance in various applications. One crucial aspect that contributes to their resilience is the IK test. In this article, we will […]
Why it requires Thyristor controlled switching modules for Dynamic power factor correction Capacitor Banks except power Contactors?
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 […]
Temperature Rise During Short Circuit
During a short circuit there will be electromagnetic forces which determine the required busbar size and the support size. In addition to that we need to be careful about the extreme overheating of the busbars due to the high current, which leads to softening of the material and damage to the support structure. At the […]
Effects of Harmonics for power factor correction Capacitor Banks
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 […]
Why a surge protective device required?
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. […]
Capacitor Banks Do Need Maintenance
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 […]
