Harmonic Generation in Motor Drives
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, […]
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, […]
Safeguarding Electrical Systems: Best Practices for Switchboard Earthing
Introduction Electrical switchboards serve as the nerve centers of power distribution in buildings, industries, and various facilities. The smooth operation of these vital systems hinges on their proper earthing. Earthing, or grounding, of electrical switchboards is a critical safety measure that must be meticulously implemented to prevent accidents, ensure equipment longevity, and maintain uninterrupted power […]
Current Transformer Fundamentals
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 […]
Powder Coating – Importance of maintaining bath concentration in conversion coating tanks
Pretreatment is the most important step when powder coating process is concerned. Pretreatment process usually does the removal of contaminants on metal surface which enhance coating performance. Once the rust, oil and scale are chemically cleaned by the pretreatment system, the base metal is exposed for oxidation. To avoid this, the material has to be […]

This study was carried out to identify and rectify, what initially seemed to be a malfunction of a power factor correction capacitor panel (PFCCP) (Power factor improvement). However during the study it was identified that the problem was […]
Understanding and Mitigating Harmonics in Welding Processes
Introduction Harmonics in welding processes refer to the presence of unwanted electrical frequencies that can negatively impact the welding operation. These harmonics are generated due to various factors within the welding equipment and power distribution systems. Understanding and managing harmonics in welding are crucial for ensuring weld quality, prolonging equipment life, and promoting a […]
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 […]
