INDIAN ELECTRICITY RULES (PART-1)

 WHAT IS INDIAN ELECTRICITY RULES?

Indian Electricity Rule

Indian electricity rule is a rule that is follow by generation,transmission and distribution company as well as consumer.This rule is very helpful for smooth operation of electric generation,transmission and distribution in our country.

The company or consumer who does not follow this rule can be penalized. So,the knowledge of electricity rule is necessary for company as well as consumer.Now we will discuss all the electricity rule one by one.

The Indian electricity rule is define below:

Rule 28: Related to voltage

Voltage: The work done to bringing a unit positive charge from infinity to that point in electric field.

OR

It is an electric pressure that is responsible for flow of current in electric circuit.

Its unit is volt and measure with voltmeter that is connected parallel to the circuit.

According to rule 28 the voltage is categories as given below:

1. Low Voltage: Does not exceed 250V.
2. Medium Voltage: 250V to 650V
3. High Voltage: 650V to 33 kV
4. Extra high Voltage: above 33 kV

Note- (a)The voltage variation between low and medium voltage is up to +/-6%.(But in practical in distribution system the variation is +/-10%).

(b)The variation in case of high and extra high voltage is up to +/-12.5%.

Rule 31

According to this rule electrical supplier is responsible for provide fuse unit or MCB to the consumer.

Rule 32

The electric supplier should be mark on earthed or neutral conductor and this is the property of supplier.Thus it is very useful for connection of consumers.

Rule 33

If the consumer uses medium,high or extra high voltage,than he should be install his own earthing system.The responsibility of maintenance of earthing system should be the consumer.

Rule 34  

The bare conductor should be install at proper height.Its height such that it is not come in contact with person without the help of stair,table etc.A switch is also install with the bare conductor.This switch is helpful at the time of emergency or at the time of work for deading the conductor.

Rule 35

The consumer must install danger plate at medium,high and extra high voltage site where transformer,generator and other electric equipment install.

Rule 36 

Before doing work on electric equipment,the metal body of equipment should be earthed thus it discharge the charges on metal body of electric equipment.

Rule 38 

The insulation of cable that is connected to electric equipment (motor,generator,welding set etc) should be better quality and it should be work properly in every type of environment.

If the sheath of cable is metal than it is connected to frame of equipment and it should be earthed.

Rule 42 

If the AC and DC circuit is available on same pole than there should be proper distancing between them that prevent the short circuiting between them.

All the electric equipment connected such that it works on rated voltage means at the time of high voltage the electric accident should not be occur.

Rule 43 

At generating stations and substations for fire extinguishing bucket of clean and dry sand and fire extinguisher is necessary.The first aid box is also very necessary.

→All the staff should be trained for using fire extinguisher and first aid box.

Rule 44 

On all electric site (generating stations,substations,factory etc) the shock treatment charts must be install.

Rule 45

The electric installation (electrical fitting,electrical repairing etc) work should be completed be licences contractor or lineman.If electric work done is completed by unlicensed contractor or lineman the supplier should be deny for electric connection

→The general maintenance could be done by unlicensed person.

Rule 46

The periodic inspection and testing of electric installation should be done by after every 5 years.The inspection fees should be pay by the consumer.

Rule 47

Before giving connection to consumer the supplier survey (inspection and testing) the electric installation.If supplier found such things that effect the supply system than supplier can deny for connection and advice consumer for improvement in electric installation.

→If every thing is satisfactory at electric installation than supplier is agree for electric connection to consumer.

Rule 48

If the value of leakage current in any electric installation is more than 1/5000 to the total electric current than supplier can be deny for electric connection.

Rule 49

If the value of leakage current in any electric installation is more than 1/5000 to the total electric current than supplier can cut the supply of consumer by giving the notice of 48 hours and supplier restore the supply of consumer when supplier is satisfy that the reason of leakage current is rectify.

Rule 50

The consumer should be fulfill given below condition for electric connection:

1. There should be a main switch (circuit breaker,linked switch) that is mainly situated near the incoming of supply and it is capable of break the main supply of electric installation.
2. Every circuit has a fuse and main switch.
3. The live conductor should not be placed in open.
4. Insulating material such that it is not affected by weather and environment.
5. All the electric equipment has a switch that is helpful at the time of ON/OFF of electric equipment.

Conclusion: Thus final conclusion is that the knowledge of Indian electricity rule is good for both supplier as well as consumer and it prevent from any type of electrical accident.
