In electrical system fuse acts as protection device and
depending on application different type of fuse is to
select. Out of these different type of fuses HRC is also
one of the type and it stands for " High Rupting Capacity".
This type of fuses normally used where some delay is
acceptable for protecting the system.

High Repurting Capacity.

Answer / rajesh kumar singh

H.R.C fuses means high rupturing capacity fuses.H.R.C fuses
acts as secondary protecting devices[back up
protection].primary protection is provided by Over Load
relays.

High rupture capacity fuse

Answer / anil

High Rupturing Fuse is also like Kit Kat Fuse which is used
to protect the cicuit but the main difference is,it has arc
quenching capacity.

Answer / amit upadhyay dscl

HRC fuse is high rupturning fuse which is secondry
protecting device. inwhich uses a arc quiched powder who
absorbed the sound and arc when element of these fuse melted
in high current condition. these fuse uses in high voltage
circuit.

Answer / jaykaran gadhvi

it is stands for high rupturing capacity fuse.

it has a advantage of current limiting featur...so its used
for protection of contactors which may melt for higher
value of current...you can see the autometic starter of
motor has contactors.used for swiching..so fuse is
connected in series with it..after 2 to 3 operation..there
will no us of fuse...as it melts due to overheating...for
30 ka short circuit current..it limits to 10 ka
current.s.c..which is the rating of contactors

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.

i work as a technician at a private company.. i used to take amp reading for certain appliances such as air con.. the problem is when i clamp the neutral, wire there is a current reading.. from my understanding for single phase system neutral should not have current unless if the circuit is not complete.. yet the air con still work

is KVAR (not reverse power) relay necessary to protect from excitor field failure on a brushless, synchroneus generator? Some people with previos experince tell me no but the manufacturers tell me it is designed for that purpose. Is it that it is only necessary for brushless generators and not the older style with the slip rings and brushes?
