Transmission Electrical Energy Equipment

A reactor is actually a coil with having several turns and much greater ohmic resistance value. Electrical Reactors are typically used to limit the short-circuit currents which can potentially cause damage to some equipment of the power system. The additional reactance which is added in series in order to protect the system is called reactors. A current limiting reactor is just another type of it which limits the heavily flowing current through other sections. This way, in case of issues we can simply isolate the faulty section instead of shutting down the entire power system. Reactors in substations are used for two main reasons : •      For lightly loaded substations connected to the end of long, high-voltage, transmission lines, the voltage may turn out to be unnecessarily high because of the Ferranti Effect. A shunt reactor can be utilized (exchanged online) to assimilate a bit of the reactive power produced by the appropriated capacitance of the transmission li

Have you ever wondered how these huge powerhouses are working to provide us the electricity supply 24X7? You must have seen different sized transformers, electricity poles, and other huge electric wireline arrangements. The electricity that comes to our homes reaches us traveling a long way going through different electrical components and line trap is one of the most significant among them. The AC line trap is actually a form of ‘parallel resonant circuit’ which is generally tuned to the carrier energy frequency. A parallel resonant circuit usually has high impedance at the frequency it is tuned with, therefore makes most of the carrier energy to flow nicely toward the remote line terminal. Whereas, the line trap’s coil offers a low impedance path for the power frequency of energy to flow well. As the power flow may get large at times, the coil used in a line trap should also be large in size. Hence a line trap is inserted between the connection of a coupling ca
