If a 6.6KV Motor run at 415V then what happen to its current and RPM?

Current shall increase while you apply 415V for operating it and will decrease the rpm to a much low level.

Where can use voltage of 415v 11kv 66kv 33kv and 132kv?
These are the nominal voltages used by the UK's distribution system, although (to comply with European Harmonisation requirements, 415 V has now been 'replaced' with 400 V. Incidentally, the symbol for the volt is a capital 'V', not a lower-case 'v'.
How many suspenssion type insulation used in 66kv transmission line?
one insulator unit can bare 11kV. such that 66kV tx line needs 6 insulator units.
What is maximum transmission voltage in Pakistan?
It is 500kv between rahim yar khan and multan.
How many volts in three phase?
Three phase refers to have the power over three lines one delayed by one third of the electrical cycle and the other by two thirds. (The first line is not delayed) Three number of phases has no relationship to the voltage (or frequency for that matter). Power can be delivered by three phase in any voltage whatsoever and there is no reason why the power could not be 1 volt (OK, not really practical) or could be over 660,000 volts and this is very common. Often voltages are 415, 3,300 (3.3kv), 6,600(6.6kv), 66kv and 132kv but these are just examples from my experience. Power voltage throughout the world varies enormously and so it is impossible to stipulate a voltage.
How works oil circuit breakers?
A circuit breaker is a safety device that is put in an electrical circuit. When something fails, or shorts out, the circuit breaker "senses" the excessive current and automatically opens (or breaks) the circuit. They are used in homes, as well as some electrical devices. They are different than a fuse in that a circuit breaker can be reset. A fuse on the other hand, has to be replaced once it opens up. I hope this helps you. for more info, here is a web page about circuit breakers: <a href="http://www.wisegeek.com/what-is-a-circuit-breaker.htm">Ciruit breakers</a>
What is Procedure the procedure to select CT's and PT's in 66kV and above substation?
You need to required following data Voltage Level, Current, Protection Class, SC Current

What is the voltage coming out of a station?
Depends on the sub station. It could be 11KV, 33KV, 66KV,110KV, 220KV, 400 KV etc
What is the voltage of high tension electrical transmissions towers?
Usually HV is 33KV and 66KV, EHV is 132KV, 220KV and 400KV and UHV is 800KV and 1200KV
Why is the rating of transformer is like 11kv 33kv 66kv?
Because the tranformer calculation for ratings is calculated with the formfactor which is 1.11 constant. Regards Mithin kudva
What is the minimum height for high power lines over a road?
On 11-66kV not less than 5,5 metres,with hazard signs on both sides indicating height of line.
What is difference between lt and ht pannel?
lt pannel is a iow tensan pannel. lt pannel work is 240v and 440v. ht pannel is a high tensan pannel . ht pannel work is 11kv,33 kv ,66kv, 120kv
Why the generating transformers are in 66kv?
As we all know that at the generating station if the the voltage ratings are at higher level like 66 KVto 132 KVso due to it we can obtain a good transmission line with a lower voltage drop and also the voltage ratings can be decreased with the help of step up or step down transformer upto10% very easily at the receiving station.Thanks & RegardsMithinKudva
What is the Phase to phase voltage of 66KV earthed cable?
Nominal transmission and distribution voltages are line voltages. So '66 kV' is a line-to-line voltage. Note that there is no such thing as a 'phase-to-phase' voltage -the correct term is 'line-to-line'. Using the term, 'phase-to-phase', indicates a lack of understanding of a.c., which is not uncommon! Incidentally, the symbol is 'kV', not 'KV'.
How many volts can transmission wire carry?
Transmission voltages are usually considered to be 110 kV and above. Where higher capacity is needed the line conductors are grouped in to three and four groups per phase leg. Voltages less than 33 kV are usually used for distribution by the utility companies.The utility company then supplies the transformers to drop the voltage even lower so that it can be brought to homes to be used by their customers.The transmission lines are of a composite arrangement.
