PRINCIPLES OF OPERATION OF SYNCHRONOUS MACHINES The synchronous electrical generator (also called alternator) belongs to the family of electric rotating machines. Other members of the family are the directcurrent (dc) motor or generator, the induction motor or generator, and a number of derivatives of all these three.
The work performed by an electrical current is called Power. The unit of Power is the Watt. Resistance (R) Conductors are not perfect. They resist to some degree the flow of current. The unit of resistance is the Ohm. Load The part of the circuit which performs work ( a motor, a light bulb or a LED, etc.) is called Load. Ohm's Law
· April 23, 2018. November 8, 2017 by admin. Trip Circuit Supervision Circuit senses any fault either in the trip coil of breaker or trip circuit. On sensing a fault, Trip Circuit Supervision Relay changes its contact status to window annunciation on the panel. Here fault in the circuit means any break or open circuit.
electrical hazards, shall be made fully aware of the hazards and should be suitably trained on how to work safely. All the work procedures should aim at minimizing exposure to electrical hazards to an acceptable level on the basis of HIRA. Energy isolation shall be done before carrying out work on electrical equipment

of electrical engineering, robotics and informatics. To tell the truth I could not find a suitable book on the whole subject and therefore I decided to write one myself. Last year I tested this book on students and the results were quite promising. Most of the students understood the electrical measurements
Different energy sources Electrical Energy, Lightning, Static Electricity, RF Energy In any discussion of the grounding of electrical systems, particularly as it applies to power systems, there also needs to be a consideration of how the grounding system relates to overcurrent protection. They go hand in hand.
· The operation principles and characteristics of the different types of electric machines are explained using brief machine descriptions, diagrams, tables etc. In contrast to other documentations on electric machines complex mathematical descriptions are avoided wherever possible.

being power or electricity. Electricity on ships is generated by an alternator or generator. Shipboard power is generated when a prime mover and alternator works together. For this purpose, an alternating current generator is used on board. The generator works on the principle that as a magnetic field rotating around a conductor varies, a
