I also faced this Question!!     Answer Posted By  
# 1
Dielectics and insulators are considered synonymous terms.
but they r not. "dielectric" is more often used to describe
materials where the dielectric polarization is important,
such as the insulating material between the metallic plates
of a capacitor, while "insulator" is more often used when
the material is being used to prevent a current flow across
Thus all dielectics are insulators but all insulators are
not dielectric.
Is This Answer Correct ?    114 Yes 29 No
# 2
the main difference between dielectric & insulator is the
dielectric used where energy is stored. like capecitor. but
in case of insulator we used it as a wall which do not
provide any path to flow current through it. the dielectric
is also a insulator.
Is This Answer Correct ?    92 Yes 13 No
# 3
The term 'dielectric' is more often used when considering
thr effect of alternating electric fieldon a substance
whereas 'insulator' is used when a material is used to
withstand high electric field.

The dielectric materials are used in capacitor like glass

Insulators wont allow any current through it... EG: Glass,

But wood cant be dielectric material... it means All the
dielectric materials are insulators... but all the
insulators are not dielectric materials...
Is This Answer Correct ?    4 Yes 0 No
# 5
the dielectric used where the energy is stored.... example
of capacitor.

insulators are used as wall which does not provide path for
flowing to current through it..

The difference between dielectric and insulator lies in its
field of application. Dielectrics are used to store the
electric charges, while insulators are used to block the
flow of electric charges (they more or less act like a
wall). While all dielectrics are insulators (they don't
allow the flow of electric charges through them) all
insulators aren't dielectric because they can't store
charges unlike dielectrics.

The difference between dielectrics and insulators depends on the field of application.That means, dielectrics are used to store electric charges and even can conduct electricity after its dielectric strength(which is the strength of the dielectric to store charges with maximum value of electric field, This situation,when dielectric conducts electricity breaking down its main property of storing charges, is known as dielectric breakdown ).
Whereas Insulators neither store electric charges nor conduct electricity in any situation.
Is This Answer Correct ?    3 Yes 7 No

# 8
All insulators are dielectric but all dielectrics are not
insulators.This means only certain insulators can posses
dielectric,where an insulator gets a minimum charge in the
presence of electric field known as dielectric.

what ll happen to current if two phases get short circuited Kirloskar 1
Dear All, In a 400V power system, ratio of three current transformers installed incoming switchgear is 4000/1. Maximum three phases short circuit current of this system is 48kA. One CT is installed on neutral of upstream transformer (6/0.42kV, solidly earthed) for 51G protection. Would you please inform me about the correct CT ratio of this current transformer (on neutral)?? Thanks a million   2
