Safety with IE Rules
The Electricity Act, 2003 is an Act of the Parliament of India enacted to transform the power sector in India.
The act covers major issues involving generation, distribution, transmission and trading in power. While some of the sections have already been enacted and are yielding benefits, there are a few other sections that are yet to be fully enforced till date
Before Electricity Act, 2003, the Indian Electricity sector was guided by
The Indian Electricity Act, 1910 and The Electricity (Supply) Act, 1948 and the
Electricity Regulatory Commission Act, 1998. The generation, distribution and
transmission were carried out mainly by the State Electricity Boards in various
States. Due to politico-economic situation, the cross-subsidies reached at an
unsustainable level. For the purpose of distancing state governments from
tariff determination, The Electricity Regulatory Commissions Act was enacted in
1998. So as to reform electricity sector further by participation of private
sector and to bring in competition, Electricity Act was enacted in 2003
CEAR namely Central Electricity Authority (Measures relating to Safety and
Electric Supply) Regulations, 2010 are regulations framed by Central
Electricity Authority of India under Indian Electricity Act, 2003, to regulate
measures relating to safety and electric supply in India
Earthing provisions and safety
Under CEAR, rule 41, there is specific provision of earthing neutral wire of a 3-phase, 4-wire system and the additional third wire of a 2- phase, 3-wire system. Earthing is to be done with two separate connections. Grounding system also to have minimum two or more earth pits (electrode) such that proper grounding takes place. As per the rule 42, installation with load above 5 KW exceeding 250Volt shall have suitable Earth leakage protective device to isolate the load in case of earth fault or leakage.[3]
Neutral and earth run separately on overhead line/cables. Separate conductor for overhead lines and armoring of cables are used for earth connection. Additional earth electrodes/pits are installed at user ends for proper earth.
