Prevent Fires Before They Start: The Critical Role of Arc Fault Detection Devices (AFDDs) in Electrical Safety
Why AFDDs? Did you know that a significant number of building fires are sparked by faults in electrical installations? Aging cables, improper installation, or even a nibble from a curious rodent can damage cable insulation, leading to arc faults. These dangerous discharges of electricity between wires generate intense heat, posing a serious fire risk if […]
Understanding Isolation Transformers: Function, Theory, and Applications
What is an Isolation Transformer? An isolation transformer is a type of transformer used to transfer electrical power from an alternating current (AC) power source to a device or circuit while isolating the powered device from the power source. This is achieved without direct electrical connection, providing safety and noise reduction benefits. How Does an […]
PROCESS OF SELECTING THE CORRECT BUSBAR SUPPORTS AND IT’S IMPORTANCE
Importance of Busbar Supports in LV Switchgears Busbar supports play vital role in Low Voltage switchgears. Main idea is to hold and provide insulation to conductive busbars, which carry electrical currents inside the switchgear. These busbar supports secure the spacing between them and the proper alignment, avoiding any accidental contacts or minimizing the risk of […]
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 […]
