Tension is a French word for Voltage. A low-tension line is a low voltage line and a high-tension line is a high voltage line. In India LT supply is of 400 Volts for three-phase connection and 230 Volts for single-phase connection. High tension or HT supply is applicable for bulk power purchasers who need 11 kilo-Volts or above. Most small consumers of electricity like individual houses, shops, small offices and smaller manufacturing units get their electricity on LT connection. HT is applicable for bulk purchasers of electricity like industries (big manufacturing units), big offices, Universities, hostels and even residential colonies (if the apartment complexes purchase together in bulk). The tariff structures of most state distribution companies are different for LT and HT.
Electrical wiring is commonly understood to be an electrical installation for operation by end users within a building, an engineered structure or a designated outdoor location. It includes the cabling and associated devices such as switches, distribution boards, sockets and light fittings but does not cover the transmission of electrical power to the installation.
Such wiring is subject to rigorous safety standards for design and installation. Allowable Wires and cables types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals. Associated circuit protection, control and distribution devices within a building's wiring system are subject to voltage, current and functional specification.
Joining electrical power cables can be as simple as twisting the wires and taping them or more detailed using a variety of inline adapters and connectors. The method used for a particular joint depends on the voltage, type of cable, type of joint, type of connector, application and other factors.
Regardless of the method used, it is important to have the proper tools and materials. Some of the key factors that ensure clean, safe and reliable connections are
> Using the proper size of the connector for the particular cable
> Proper tools
> Clean cuts and stripping
> Restoring the insulation, armor and outer-sheath
> Proper technique

The technology of using LAN data networks rather than traditional telephone lines and a PBXto carry voice traffic along with the data traffic that is typical of a LAN system.
A LAN telephony system requires both a device to process incoming and outgoing calls to determine what address on the LAN a call will be sent to and also a voice gateway that connects the LAN telephony system to the PSTN. Each telephone on the LAN has its own network address and converts audio signals to digitized packets for transmission across the LAN. When a call is received from outside the LAN, the call processor determines which network address receives the call and forwards the packets to that address. When a call originates within the LAN, the call processor determines if the packet is to be forwarded to another network address or to the PSTN, in which case the packets must travel through the voice gateway.
Maintenance Engineering is the discipline and profession of applying engineering concepts for the optimization of equipment, procedures, and departmental budgets to achieve better maintainability, reliability, and availability of equipment.
Maintenance, and hence maintenance engineering, is increasing in importance due to rising amounts of equipment, systems, machineries and infrastructure. Since the Industrial Revolution, devices, equipment, machinery and structures have grown increasingly complex, requiring a host of personnel, vocations and related systems needed to maintain them. A person practicing Maintenance Engineering is known as a Maintenance Engineer.
