MCB (Miniature Circuit Breaker), Construction, Working, Types & Uses https://www.electricaltechnology.org/2016/02/mcb-miniature-circuit-breaker-types-construction-working-uses.html MCBs are used primarily as an alternative to the fuse switch in most of the circuits. A wide variety of MCBs have been in use nowadays in all areas of domestic, commercial and industrial applications as a reliable means of protection. Air Circuit Breaker (ACB) →
Most people know circuit breakers and fuses. Quite many also know ground fault circuit interrupter (GFCI) or Residual Current Device (RCD). But now a new protective device is coming to use in Europe and you might want to learn about it. AFDD/AFCI Arc Fault Protection Device protects people and property against fires caused by arc →
Electrical power is amazing and dangerous at high voltages. Electrical substation is a part of an electrical generation, transmission, and distribution system that transform voltage from high to low, or the reverse, or control the flow of electrical power. Substations may be owned and operated by an electrical utility, or may be owned by a →

https://spectrum.ieee.org/energywise/energy/the-smarter-grid/chinas-state-grid-corp-crushes-power-transmission-records State Grid’s new 1100-kv line could help reduce renewable energy curtailment because Xinjiang’s wind and solar power plants are among China’s largest and also the country’s most heavily curtailed. Challenges associated with absorbing power injected by big DC lines led to the break-up of China’s southern grid in 2016. State Grid is counting on →
An optical ground wire (OPGW or an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications. It has optical fibers in it, surrounded by layers of steel and aluminum wire. Here is one example of such system →
Crimp connectors are typically used to terminate stranded wire. A well-engineered and well-executed crimp is designed to be gas-tight, which prevents oxygen and moisture from reaching the metals (which are often different metals) and causing corrosion. Wire crimping is typically a three step process that needs suitable connector and suitable crimping tool: In the first →
I have written about fluorescent lights technology and fire dangers related to fluorescent lights. I had earlier covered the problems related to starter, bad tube and ballast overheating. Now there is another risk to consider: most fluorescent lamps powered from 230V AC have a filtering capacitor on power input between live and neutral. This is →
Christmas lights can be a beautiful sight to behold. Stringing lights around your home can be a real safety hazard if you’re not careful. For outdoors use the lights you need to have lights that are designed to be used outdoors. The lights made for outdoors used can withstand the outdoors conditions – meaning possibly →
A switching-mode power supply (SMPS) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or lighter weight are required. The main advantage of the switching power supply is greater efficiency than linear regulators. The downside of →
