Answer / anindya chitta bagchi
relay is an electromechanical/electronic device,that picks up
when certain conditions are met,and then makes normally closed
contacts open,and normally open contacts closed.
| Is This Answer Correct ? | 2 Yes | 1 No |
Answer / ecstatic
Relay is a device used in protection system which senses
any abnormal condition in an electrical circuit and
triggers the trip coil \../
it can also be defined as an electromagnetic switch used to
control high voltage through low voltage ..
| Is This Answer Correct ? | 3 Yes | 2 No |
Answer / sush
Relay is like switch having Normaly open, Normaly close &
combination of both.In relay tere is electro magnetic coil
which is energized when supply is given and atract the
armature to make the contact.
| Is This Answer Correct ? | 2 Yes | 2 No |
Answer / hemant
relay is an sensing device. it senses the fault condition & energises the CB coil.
| Is This Answer Correct ? | 1 Yes | 2 No |
Answer / gunnam santosh
basically relays are coils designed for certain current
rating if current flowing through it increases this rating
it gets energised and operates the centrifugal switch placed
in it and opens the switch.

What are merits & De-merits of State-Space Method? What is series programming, parallel programming, general programming & direct programming ? And, difference between these programmings Techniques ?
What is the difference between power cable and signal cable (only Observation Difference)?
Generally we denote power in 'p',voltage in 'v'but why can't we denote current in 'c' instead of I.
where is used dc volage transformer,and what is highest capacity of transformer
what is the difference between potential transformer and capacitive voltage transformer?
what is electric current
what is active power & reactive power?
As all us know that the capacitor panel is connected to improve the power factor when it is PF is low. whether we can connect the capacitor panel on D.G. side(? If it is yes means why?
A 3ph load of 10 KW is equal to how many KW of single phase .
(1)Electrical power is generated in KV, power consunmed is in MW and the transformers used are in KVA. How is KVA converted to MW as power being consumed by the consumers? (2)What is vector group of a transformer?
why we use to transmit the power in three phases intead of single phase ?
why shoud in High tension cable( above11KV etc.,)a semiconducting material coating will be there on insulation?
