Motor converts the electricity to mechanical work.
Pump is a device to force a gas or liquid to move in a
particular direction

Answer / alianwar

MOTOR : An electric motor uses electrical energy to produce
mechanical energy, usually through the interaction of
magnetic fields and current-carrying conductors. The
reverse process, producing electrical energy from
mechanical energy.
PUMP : A pump is a device used to move fluids, such as
gases, liquids or slurries. A pump displaces a volume by
physical or mechanical action. One common misconception
about pumps is the thought that they create pressure. Pumps
alone do not create pressure; they only displace fluid,
causing a flow. Adding resistance to flow causes pressure.
Pumps fall into five major groups: direct lift,
displacement, velocity, buoyancy and gravity pumps

Answer / ln sahu db power

motor is a electrical device which convert electrical power
into mechanical power. it is named according to their

Just a silly question but just to make my curious mind bac to normal - Why was not 67 and 67N relays built into a single relay as i have noticed that the R,Y,B CT wiring end up into the 67 relay while the common of the R,Y,B CT wiring end up into the 67N relay. Then it was better if a single relay was manufactured just like the distance relay (21). Another question i would like to ask is - how do we know where the 67 and 67 N relay has to be placed.why is it not placed at the transformer bay? In the substaion that i am working -i have noticed that it is placed between a breaker and a common double bus bar and this line bay is connected to another substation at a remote place which is furthur connected to a load.
