Security and Access Control Systems (SACS) for Critical Security Areas

Special areas like Airports, Port Trusts, Naval Base, Military base, Telecom buildings, Refinery, Petroleum handling areas etc. needed highly sophisticated security and access control system. It provides safety and security for both men and equipment the area handling. Here is the specification and installation methods for SACS.

Electrical Engineering

Electrical engineering deals with practical applications involving current flow through conductors; focuses on the design, construction, and operation of electrical systems and equipment. It includes developing, producing and testing of electrical and electronic devices and equipment, such as, generators to produce and distribute electricity, electric motors and other electrical machinery, transmission line.

Typical Installation Details and Drawings

Construction projects highly depends on typical installation details and drawings. Architects and engineers use this kind of information to reduce their work load. Employees particularly technicians and foremen who execute the project uses typical drawings as general guidelines where repeated structure, forms, shapes, operations, loads, etc. come into force.

Mechanical Services In MEP Construction

Particular Specification For Mechanical Services describes various general requirements In MEP Construction Work, a contractor to follow when they start executing but not limited to unforeseen work or requirements to accomplish the whole project contract.

Electrical Grounding or Earthing Conductors in Building Construction

Buried Earth Conductors:

PVC insulated copper strip conductors or PVC insulated stranded copper cables with cross-section min 70 mm2 or as per earthing calculation.

Earthing Conductors:

PVC insulated copper conductor as described in the Specification for the particular application.

Earthing or Grounding Methods for Plant Rooms And Fixed Machinery

Main earthing bar or loop is to be conveniently located in electrical/mechanical plant rooms, and connected by earthing conductors to exposed conductive parts of motor control centre at its earthing bar, and to motors, switches and other electrical equipment etc. at their earthing terminals, using 20 x 2 mm insulated copper strips or 35 mm2 insulated copper conductor (minimum size) or as required to carry maximum earth fault current for 1 second with final conductor temperature not exceeding 200 deg. C (392 deg. F).

Emergency Power Diesel Generating Set In Electrical Construction

This article covers the manufacture, supply, installation, testing and commissioning of 415 volts, 3 ph, 4 wire, Diesel Alternator Set (Diesel Genset). The set shall be mounted on common base frame and complete in all respects including the auxiliary equipment such as battery auxiliary, lube oil pumps, filters, oil storage tank, centrifuge, etc. including piping required for interconnection between the set and the auxiliaries which are mounted separately.

Electrical Earthing or Grounding Method for Road Lighting

A. Earthing Cables: Separate protective earthing cables for lighting column circuits are to be run with power circuit, terminated at LV supply position in lighting control panel and looped into column earthing terminals. The last column is to be bonded via an earthing bolt to a single 16 mm diameter stainless steel rod, 3.6 m long, driven into ground adjacent to column. Bonding is to be 16 mm2 stranded bare copper conductor.

Installation of Structured Cabling For Voice / Data System In Building Construction

The Contractor shall design, supply and install outlet plates, conduits, trunking, trays, wiring, junction boxes, distribution frames, patch panels, data rack, backbone cables, etc. necessary to form a complete structured system for voice and data cabling within the buildings. Cabling / wiring shall be provided for voice system from patch panel location to each voice/data outlet. Draw wires shall be provided in conduits for future data cabling / wiring by others (if applicable). The installation shall comply with the requirements of ANSI / EIA / TIA-568-1991 as appropriate as well as Local Telecom Authority.

Voice and data outlet plates shall be designed to accept industry standard RJ45 plugs.

General Questions And Answers In Engineering and Technology

What Is Engineering? Engineering is an art of applying science to the optimum conversion of the resources of nature to the uses of humankind. It is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, transfer and rate processes, and systems analysis. It is thus we must define Engineering: "the practical application of science and math to commerce or industry". In other words "the art or science of applying scientific knowledge to practical problems".

Transformers in MV Distribution System

This specification intended to supply, install, test and commission mineral oil immersed 1500 KVA, 3 phase indoor transformers, fitted with cable boxes, bolts, and all necessary accessories. Transformers shall be indoor type, oil filled, two winding, four off load capacity, 2.5% taps, two above and two below high voltage rating in compliance with IEC 76 or BS 171.

Quality Plan for Construction Projects

It is essential that services and systems in a building construction contract work are provided to conform to the requirements of the customer, and that the activities be effected as economically as practical. The achievement of these objectives is facilitated by setting up working procedures and practices, which collectively provide a “Work Efficient”, yet controlled operating environment. It is the purpose of this Construction Quality Plan to give instruction to personnel, on the implementation of the company system such that the above objectives are accomplished. Documentation specific to the project will be provided to ensure full compliance with the particular requirements of the contract.

Electric Appliances

First of all, we have to look into what is the definition of Appliance in-general and specifically for Electric Appliance.

Definition of Appliance

What is the definition of Appliance? The term appliance can be defined as, "a device or apparatus or equipment designed to perform an application or task, other than industrial, benefited in our personal life that uses some kind of technology". In short, an appliance is a machine that reduces a human’s effort in carrying out a specified work or task. For example, a scissor uses to cut our hair, an iron box to ironing our clothes, a TV to watch entertainment programs and news form different parts of the world. Here, scissor uses mechanical technology to perform its function. It uses only mechanical energy that generated by parson it operates, where as, other two appliances use electricity as the source of energy to operate it. Appliances may be indoors or outdoors, fixed or portable or hand held or hand operated or remotely operated or computer controlled and there on.....
