There are so many types of electrical signals that classifying them by physical characteristics or other methods helps to organize the type of equipment needed, the necessary testing procedures and measuring equipment, and address any safety concerns or regulations. Classification of signals…

What is a Circuit breaker? A circuit breaker (CB) is an automatically operated electric switch designed to protect an electrical circuit from damage caused by an overload or short circuit. Unlike fuses, which must be replaced when they open, a circuit breaker…

The synchronous generators or alternators are rated in KVA or MVA instead of kW rating. Electrical appliances or machines generally have the rated capacity they can withstand without overheating and damaging the insulation. That is, the classification of electrical machines is governed…

Power factor correction (PFC) can be done by passive or active circuits. Advances in semiconductor technology and low prices of control integrated circuits have made the use of active solutions for PFCs more appropriate for various applications. What is Power Factor (PF)?…

Modern DC and AC motors provide useful features when using electric motors as final control elements. Here are some common features that are seen in both VSDs and VFDs. Speed limiting Torque limiting Limitation of acceleration (speed of change) Limitation of deceleration…

What is zener diode regulator? Zener diode regulator is an electronic device designed to protect electrical and electronic devices sensitive to variations in potential difference or voltage and noise in the alternating current of the electrical distribution The zener regulator can regulate…

Electric motor is an essential electrical device in the home and industries. In general, in large organizations, an engine maintenance program is carried out in which the causes of the engine failures are identified and the necessary measures are taken to avoid…

Motor controllers range from a simple switch to a complex system that uses solenoids, relays and timers. The basic functions of a motor controller are to control and protect the operation of an engine. This includes starting and stopping the engine, and…

What is Multi-conductor cable? Multi-conductor cables are a single variation of twisted cable, and each cable houses at least two (and often many) different conductors within a common housing. Depending on the configuration, these cables can offer up to 60 different conductors,…
