Electricity . is a secondary energy source, . i.e. . it comes from the conversion of other sources of energy, such as coal, natural gas, oil, wood and nuclear power.. Steve Rainwater. Energy System Operations Trainer (LCRA). The objective of this class is to provide the student with a general knowledge of the fundamentals of transformer protection. Enabling Objectives. Single Phase Transformer. A . transformer is an electrical device that is used to raise or lower the voltage (or current) level. . A . single-phase transformer has two electrically isolated windings. . Single Phase Transformer. A . transformer is an electrical device that is used to raise or lower the voltage (or current) level. . A . single-phase transformer has two electrically isolated windings. . ig. 2. Distribution transformer protected with spark gap according to the SFS 2646 standard [6]. III. SERIES IMPEDANCE BASED PROTECTION n alternative to a special transformer design is to intro Tunnel Boring Machine(TBM) Most of the parts work with use of electrical motors and . consumes electrical power, generating electrical power on site with use of generators and connection also with government supply, this supply(11KV) reach to TBM after synchronization of generators with use of power cables and junction boxes, Step down this power with use of Transformer(11KV/690-400V) and Consuming this power for operation of TBM.. Introduction. Transformer . is the main reason to transmit and distribute power in AC. Transformer is a device which works on the principle of mutual induction. . Principle. . of operation. It is based on principle of . The transformer is a static device which is used to transfer electrical energy from one ac circuit to another ac circuit. . Input to a transformer and output from a transformer both are alternating quantities (AC).. El-Sharkawi@University of Washington. 2. Why do we need transformers?. Increase voltage of generator’s output. Transmit high power at low current. Reduce cost of transmission system. Adjust voltage to a usable level. PREPARED BY:. VRUNDA RANA (131130107049). KRIMA .
