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.

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.

Guidelines for Installation of Emergency Power Diesel Generating Set

We often depends Diesel Electrical Genset as emergency power system due to mains failure. As a professional, the installation of diesel electrical power generator should be as per the clients requirement and to be inline with the authoritative norms and standards. Safety, security, convenience, future expansions etc are to be considered and co-ordinated before start detailing of the genset's installation. The generator should be as close to the main change-over board as possible. In cases like Textile Mills, where there is fear of smoke affecting the quality of the yarn etc., generators may be located away from the Plant / Department.

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.

Definitions of Electrical Earthing / Grounding Terms

In electrical projects, both construction as well as maintenance, the following terms used on the Drawings, Specifications and in the actual Work site are equivalent and may be used interchangeably: "earth" and "ground"; "earthing" and "grounding". Besides, this article tries to rectify misinterpretation of some important terms often used by people involved in the electrical earthing / grounding work.

Automatic Transfer Switch (ATS) OR Automatic Mains Failure (AMF) Panel

Reliable electrical power becomes one of the most wanted factor in modern world industry where operation should be uninterruptible and maximize the cycle of operation, output quality and to avoid losses and damages. Here we are talking about Automatic Transfer Switches (ATS) also known as Automatic Mains Failure (AMF) panel to cater uninterrupted power supply from Mains or backup sources like Diesel gen-set, static ups etc.

What is Automatic Transfer Switch (ATS)?

Automatic Transfer Switch (ATS) is an automated switching device that transfers load power to backup power during mains failure and back to its original state when mains power reinstate to the normal condition. It will have its own contacts, microprocessor to analyses the conditions whether power supply is normal or backup and need backup or mains power. Here "back up power" may become either Standby generator or another mains power or static power source like UPS.


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.

Refrigeration Plant in MEP Construction

In this sample MEP specification section, Mechanical Refrigeration Plant has been described in detail under construction contract work. Main Highlights of this MEP Specification are: General Requirements, Compressors, Evaporators, Condensers, Condensing Units, Refrigeration Plant Accessories, Pipework, Valves and Ancillaries, Insulation, and Controls.

Public Address System In Electrical Construction Contract

The contractor shall supply, installation, test and commission a public address system consisting of power amplifier, mixer power amplifier, microphone module, paging console, cabinet rack, conduits and wiring and all the necessary equipment required by the system shown and described on drawings, bill of quantities and hereinafter.

Temporary Utilities of Water, Electricity, A/C, Lighting For Construction Site

It will be the Developers responsibility to obtain all necessary approvals from Authorities having jurisdiction for temporary connections to existing infrastructure. Temporary utilities shall be installed in such a manner as not to interfere with permanent construction. The Plot Developer shall provide any temporary holes or sleeves required to install the temporary utilities and shall be responsible to fill the same upon removal of utilities.

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.

Construction Control Guidelines

Construction Control Guidelines of project will help participants to establish right relationship with each other. It explains guidelines and minimum requirements that must be adhered to by developers for the duration of their construction activities. It can be listed as follows:

Indoor MV Distribution Panel Boards In Electrical Construction Works

Building projects requires MV Distribution Panel Boards for distribution of power to each utilities. A good electrical distribution network will have proper design, right components, and future load provisions. Space utilization will also be an important factor for maintenance and handling of the equipment. Here we look into what are the features required for design, manufacture, install a MV Distribution panel board including its BIS (IS) standards that serving quality building projects.

Engineering and Technology

Engineering and Technologies are, in the first instance, simply extensions of the human body, allowing us to overcome the physical limitations with which we are born, and to adapt the natural environment to our own needs. Technologies are inventions of humans that have allowed us to survive, and have enabled our cultures to advance. They are for the most part material objects: tools, for example, are simply detachable additions to the body, the manufacture of which generally distinguishes humans from animals.
