Technical articles on Electronics and Electrical Engineering topics focused on Basics of EE, Electronic components, power systems and equipment used for generation, transmission, operation, and controls of electricity.
Isolators and circuit breakers are two electrical devices that are commonly found in industrial installations. The isolator is an offload device, while circuit breaker is on load device. The isolator is used for isolating a portion of the power system. The circuit breaker is used for switching purposes. Isolator should be operated after switching off the … Read more
A well-designed power system ensures a continuous supply of electricity to its consumers. Whilst continuous supply at an economical equally beneficial rate is the supplier’s preference, the power engineers are often interested to reduce transmission line losses. Given below are the 5 methods in this case: Higher transmission voltages The line drops in a transmission … Read more
Batteries are often wired in series and parallel configurations to obtain a higher amount of voltage and current. Batteries can be added in three different configurations. Today you’ll learn the top 3 types of battery connections. Basics of Batteries Things you should know: A battery has two terminals. (SIMPLE point) The anode is the positive … Read more
Switchgear is a general term which involves protection, control, and switching equipment in a power system. According to IEC 60947, The Rated voltage of Low voltage switchgear (LV Switchgear) is up to 1000 VAC or 1500 VDC. You can watch this video to learn about different types of components: Alternatively, here is the list of … Read more
A generator is an electrical machine the converts mechanical energy into AC or DC electrical energy. On the other hand, the alternator is the type of generator which produces AC. Although generator is a general term used for any type of generator. Electrical Engineers often use Generator for representing DC generators and alternator for AC … Read more
While talking about voltage range the terms low, medium, high etc are the generic terms which depend on the particular scenario. However, in case of power transmission and distribution systems voltage can be classified into following classes: Name Range Low Voltage 50 – 1000 V Medium Voltage 1 kV – 100 kV High Voltage 100 kV … Read more
A solid wire comprises a single metalcore while a stranded wire contains a large number of twisted wires that are wrapped together to form a helix-shaped bunch. Today you’ll learn 10 essential differences between both types of wires. Let’s understand stranded vs solid wires. Flexibility The small diameter strands can easily face bending. The wire … Read more
On the basis of length, transmission lines are often classified into three groups. Class Length Short transmission line Up to 80 km (Up to 50 miles) Medium transmission line 80 – 240 km (50 – 150 mile) Long transmission line Above 240 km (> 150 miles) The classification of lines into different groups simplifies the … Read more
The HVDC or High voltage direct current power transmission comprises rectifiers and inverters for converting ac to dc and then dc to ac. The generation and distribution are still done by alternating current. Let’s understand the HVDC transmission model: Generation: Alternator generates AC Step up transformer: Voltages are stepped up for improving efficiency and reducing … Read more
Just like Humans have their sensing organs, the automobiles have their measurement tools by which they sense the environment and status of their machinery. Given below are top 15 automotive sensors which are vital for cars, vehicles and other automobiles. Airbag sensor An airbag sensor is a safety device which senses the collision/sudden deceleration of car and … Read more
