What is a surge arrester? Can surge protectors save your electronics?

Image
A surge protector is an electrical device that protects equipment from power surges and overvoltage while also blocking voltage above a safe level. When it exceeds 120 volts, the surge protector trips to ground voltage or even shuts it off. If surge protectors are not used, anything beyond 120 V can cause component difficulties such as irreversible damage, the lower lifespan of internal electronics, burnt wires, and data loss. It is one of the most important components in chemical earthing . Transient Surge Protectors aim to control the voltage provided to electric equipment by either interrupting or shorting current to minimize the voltage that falls below the safe level. You may now perform the same thing by employing an inductor that prevents an abrupt shift in the current. Spark gaps, Zener-type semiconductors, and MOVs, all of which start to conduct current after it reaches a particular voltage threshold, or by capacitors that prevent an abrupt shift in voltage also accomplis

All you need to know about copper bonded earthing rod.

Earthing is among the most important aspects to address initially to secure home safety. It is essential in protecting the user from electric shock. It protects the circuit from harm and eliminates the possibility of a wire explosion following an insulation failure. The practice of connecting the metallic portions of an electric system to the soil is referred to as chemical earthing .  Connecting a metallic section of electrical equipment to the ground plate through a robust and low resistance conductor wire is also known as Earthing or Grounding. The rod through which the over-voltages is transferred to Earth is called a  chemical earthing rod . Because of its high electrical conductivity, copper wire appears to be the greatest choice for grounding electrodes and conductors. Copper metal is corrosion-resistant, and copper electrodes survive longer in most soils than alternatives such as galvanized steel. A copper rod between 12.5 mm to 16 mm in thickness of galvanized steel is phy

What is the process of preparing hot dip gi earthing electrode?

C hemical earthing is a classic earthing method in which chemical compounds are put into earthing pits to aid improve soil quality and reducing soil resistance. An earthing electrode is utilized during lightning to dissipate the electric discharge in the ground. The assembling system of hot plunge exciting may change somewhat from one plant to another. It can portray the basic strides in the arousing system in a nutshell. The steel articles are plunged into a hot-alkaline arrangement or harsh, soft drink answer to eliminate soil, grease, shop oil, dirt, and solvent markings for diminishing and acidic cleaning. The article is plunged into a flushing tank containing clean water for cleaning.   Hot-Dip Galvanizing:   Second pickling is acted in a second pickling tank which contains weakens the arrangement of either hydrochloric or sulfuric acid 10-32% to eliminate surface rust and factory scale to give an artificially perfect metallic surface. A similar metal is again washed in

Top 10 myths debunked of lightning precaution/safety measures.

Lightning is a naturally occurring that causes electrostatic discharge, which occurs when two electrically charged locations, either in the sky or on the ground, quickly neutralize each other, leading to a rapid discharge of megawatts of energy on average. This discharge may create a wide range of electromagnetic radiation, from heat caused by rapid electron movement to dazzling bursts of light waves called black-body radiation. Thunder is a sound created by lightning triggered by a wave that occurs when gases in the discharge's vicinity experience a fast increase in pressure. Lightning lasts for a fraction of a second. A normal lightning strike contains an intensity of 300M Volts and a deadly current of 30,000 amps. It has the capability of heating the surrounding air to temperatures five times greater than those observed on the sun's surface. It is recommended to seek shelter in a home, other structure, or a hard-topped, completely enclosed vehicle during a thunderstorm

Why GI Earthing Electrode for Substation is a Must?

Image
An earthing is the technique of transmitting instantaneous discharge of electrical energy straight to the Earth via a low resistance connection.  Electrical earthing is accomplished by attaching the current-less carrying section of the electronic or electrical devices or the supply system's neutral to the ground. A  chemical earthing electrode  is a current transmitting element that is embedded directly in the ground, allowing fault currents to flow towards the earth.   Substation systems are a collection of complicated metal-consolidated devices designed to reduce high voltage energy. Because of this, substation structures are typically located outside in open areas with only a sliver of shadow protection, since they manage transmission flow. The positioning of the substation systems in open areas exposes them to elements of nature regularly.  Because the structures comprise metals, this causes corrosion. Because of the principal role of the substation construction, it is subjec
