This article gathers in view of the Shanxi Yangquan some mining area transformer substation and Hubei some pump can the power plant when the use combined type overvoltage protector appears the accident the phenomenon.Have carried on the analysis to the combined overvoltage protector principle and th...
Lightning arrestor working principleis, once the voltage surge travels throughoutthe conductorthen it reaches the location of the arrestor where it is installed. So it will break down the insulation of the lightning arrestor for a moment, so voltage surge can be discharged toward the ground. Once...
of the power grid voltages are acquired; the m2 subharmonic amplitude and the initial phase angle of the leakage currents are acquired; the effective value of the resistance leakage currents is calculated based on the harmonic superposition principle; the initial phase angles of the power grid ...
According to the working principle of the photonic sensor, it can be generally divided into two types: the internalphotoelectric sensorand the external photoelectric sensor. The latter is subdivided into the photoconductive sensor, photovoltaic sensor, and photomagnetoelectric sensor. ...
5). Why CT is used in substation? This transformer is used for measurement & protection purposes in substation Thus, this is all aboutan overview of the current transformerwhich includes its definition, working principle, construction, different types, errors, and applications. Here is a question...
Read:Substation Equipment and their working Where Rectifier Transformers are Used? Rectifier transformers are used for industrial processes which require a significant direct current (dc) supply. Rectifier circuits are used to provide high-current dc for electrochemical processes like chlorine production as...
Working Principle of Current Transformer These transformers are basically step-up transformers i.e. stepping up a voltage from primary to secondary. Thus the current reduces from primary to secondary. So from the current point of view, these step down transformer, stepping down the cur...
This curriculum designs the primary coverage is aims at some 110kv transformer substation relay protection the disposition, and based on the relay protection disposition principle, to the protection which chooses carries on the installation computation and the sensitive verification.First short-circ[transla...
Definition:Atransformerthat has a single winding is known as an Auto Transformer. The term ‘auto’ is taken from a Greek word and the meaning of this is single coil works alone. The working principle of the autotransformer is similar to a 2-winding transformer but the only difference is, ...
