Sun being the infinite source of power, Solar Energy is considered a power source that won’t ever run out. We have multiple energy resources, and most of them are running out as the demand for power increases with the advancement of technology, industrialization, and urbanization. If all the non-renewable energy…

Why are Switches used in Industries? One of the most important concerns in an electrical power system is the continuous supply of power to the load. To maintain reliability, various facilities (for example, hospitals, schools, and industries) use different backup power sources (if the primary source (utility) is affected for any reason), that is why switches…

As we are progressing in time, the non-renewable energy resources are running out and soon they won’t be enough to meet our needs. As necessity is the mother of invention, this need keeps pushing us to develop alternative energy resources which will eventually replace all the conventional energy sources one…

Q1. Breakers that can decompose the unbalanced set of phasors to their respective sequence components are electronic breakers. Is there hardware inside the breaker that can do this and thus, correctly diagnose what kind of fault is on the system? Circuit breakers do not have the ability to decompose a…

Q1.What is a Simo code and what is its function? SIMOCODE is the flexible, modular motor management system for low-voltage motors. It can easily and directly be connected to automation systems via PROFBUS or PROFINET. It combines in just one compact system all required protection, monitoring, safety, and control functions…

Q1. How will we calculate short circuit current in a specific area instead of converting all given circuit in an equivalent circuit and finally applying Ohms Law on it? Just remove all the circuits after the point at which you want to calculate the short circuit current and just attach…

Q.1 What is Admittance? (a) It is equal to the Impedance. (b) It is the square root of Impedance © It is the inverse of Impedance Answer: © It is the inverse of Impedance ✔ Explanation: (Z = 1/Y) Q.2 Which equation represents the admittance? (a) Y=R+jX (b) Y=G+jB ©…

It is essential for any power utility to provide sufficient energy enough for all the loads connected to the system. To achieve this, the generation and distribution system should be equipped with instruments to determine the maximum demand of consumers at all times. This can be done by the instrument…

What is a Ring Main Unit? In an electrical power distribution system, a ring main unit (RMU) is a factory assembled, metal enclosed set of switchgear at the load connection points of a ring-type distribution network. …
