What kind of protections must be provided to 33kv electrical feeder?

Typical protection for a radial system would be overcurrent protection - a mixture of definite time, instantaneous time, and time overcurrent for positive sequence, negative sequence, and zero sequence is usually used (negative sequence isn't used very often, but there are times when it is needed). These overcurrent protective devices will trip a breaker, circuit switcher, or similar device.
When feeds become extremely long, sometimes in-line fusing is used part way down the line as a cheap alternate to a recloser or breaker. The drawback is if a fault occurs, someone has to go out and replace the fuse, and you are typically at the mercy of the customer calling in and complaining before you will know a fuse is blown.

What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
What is the acceptable value of contact resistance for circuit breaker in service?
A low voltage (less than 1000 VAC) circuit breaker for 15 A typically has a contact resistance of 0.01 Ohm or less.
Why neatural ground resistor using in 33kv transformer?
The function of a neutral earth resistor is to limit any fault current resulting from fault between a line conductor and earth.
What is the base mva of 33Kv?
750MVA to 1000MVA for 33kV and 350MVA for 11kV
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
What is the highest generating capacity in India?
33kv
What are the effects of being at end of 33KV transmission line?
The effects of being at the end of a 33KV transmission line will result in a higher voltage. This is due to variation in the perameters that dictate how the transmission is sent and received.
What is the Phase to phase clearance for 33KV sub station?
1.2 meter
What ACSR conductor is used for 33kV transmission line?
Single Circuit PantherACSR Conductor
What is the acceptable value for 33KV switchgear?
33 KV plus or minus 3 percent
Why transmission is done on 11kv and 33kv?
High voltage reduces the amount of energy wasted in transmission lines.
What is a HG fuse?
horn Gap fuse, used in 11kV & 33kV circuits to disconnect in case of fault.
How many high tension poles is needed to transmit 33kv along 3km?
iT DEPENDS HOW FAR YOU WANT THEM SPACES
How 33kv power converts into 440volts?
33 kV (not 'kv'!) is the standard primary-distribution voltage used in the UK's electricity supply system. Low voltage (400/230 V -not 440 V) is normally provided by transformers supplied from the 11-kV system, not the 33-kV system.
What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
