Restricted Earth Fault Protection: This type of Restricted Earth Fault Protection is provided to detect earth-faults within the protected zone of the transformer. A CT is fitted in each connection…
Overcurrent Protection of Feeders: Overcurrent relays offer the cheapest and the simplest protection for lines. The maximum load currents must be known to determine whether the ratio of the minimum…
Interlocking Components in Electrical Drives: Sensing of signals required for speed and current control loops. Sequencing and interlocking operations are explained in the previous section, whereas this section discusses components…
Electrical Drive Systems: Each Electrical Drive Systems is different from other Electrical Drive Systems. However, there are some common features associated with all Electrical Drive Systems. To understand them it…
Sensors and Transducers: The definition of Sensors and Transducers are follows, The input quantity for most instrumentation systems is nonelectrical. In order to use electrical methods and techniques for measurement, the…
Transducers Articles: Electrical Transducer: A transducer is defined as a device that receives energy from one system and transmits it to another, often in a different form. Broadly defined, the…
Protection of Transformers: Transformers are static devices, totally enclosed and generally oil immersed. Therefore, chances of faults occurring on them are very rare. However, the consequences of even a rare…
Electric Motor Power Loss and Heating: An Electric Motor Power Loss and Heating occurring in its various parts such as copper losses occurring in armature and field and eddy currents…
