How does a automatic transfer switch work?
The load have deference two feeder like transformer &generator when the power of transformer shutdown the load get power from second feeder generatoraoto
Concept of maximum power transfer in transmission line?
Transfer capability in transmission system defines the capability of system to reliably transfer power from one zone to other or from one part to other without affecting system stability. Under this concept there are various terms like Available transfer capability (ATC), total transfer capability (TTC), capacity benefit margin (CBM), TRANSFER CAPABILITY MARGIN (TCM). The term maximum transfer capability is termed as Total Transfer Capability means maximum power transfer from one part to another without violating system constraints.
Explain open-loop transfer function of a close system?
An open loop transfer function is the transfer function of a system without incorporating the feedback component. For example, where the closed loop transfer function with unity feedback H(s) = G(s)/(1+G(s)) it can be deduced that the open loop transfer function is Y(s)/U(s) = G(s).
How do you bypass an electric meter?
There is no need to bypass the utility meter. In order to use power generated on site, you need to install what is called a transfer switch. The transfer switch selects either utility power (that comes through the meter), or site generated power, but never both at the same time. You then wire branch circuits from the transfer switch to the various lights, receptacles, etc. you want to power. You can buy transfer switches that have from one to 20 or more circuit breaker positions to do this.Never, ever wire site generated power directly to utility-fed circuits!This can cause severe damage, as well as hurt or kill people. If there is a power outage, and you are running your generator (or whatever), you can backfeed power onto the utility lines. The workers trying to fix the outage, can come in contact with the lines, thinking they are dead, not realizing you are backfeeding power to them. Be safe, use a transfer switch!IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
