The percentage slip of an induction motor is a measure of the difference between the synchronous speed (the speed at which the rotor would rotate if it were perfectly aligned with the stator’s magnetic...
In an electrical system, the earth’s resistance should be kept low for several reasons such as for the safety of people, protection of equipment, improved power quality, etc. A low earth resistance ensures that...
An insulator is a material or electrical device used to insulate electrical equipment and systems from each other to prevent electrical energy from flowing through unwanted paths. An insulator isolates the circuit and blocks...
For long-distance transmission electrical power is transmitted at high voltage for several reasons: Energy Loss and power loss: Energy loss can be considered as the waste of energy over a period of time due...
An Aerial Bunched Cable (ABC) is a type of overhead power distribution cable that is used to supply electricity to residential, commercial, and industrial customers. This type of cable is made up of several...
A trip circuit or TC, also known as a trip device or protective relay, is a safety feature in an electrical system that is designed to automatically disconnect the electrical power supply to certain...
A magnetic oil level gauge, also known as a magnetic float gauge, is a device used to measure the oil level inside an electrical transformer. It consists of a magnetically-sensitive float that is suspended...
Megger testing is a type of electrical testing that is used to measure the insulation resistance of electrical cables and other electrical equipment. It is also known as a “megohmmeter test” or simply a...
An earth mat is a type of electrical grounding system that is used to provide a safe and reliable path for the fault current to flow to the ground. Earth mats are typically used...
Phase imbalance in a three-phase electrical system refers to a situation where the phase-to-neutral voltages of the three phases are not equal. In a balanced three-phase system, the phase-to-neutral voltages of all three phases...
