Units space high voltage equipment

The article discussed how these systems have evolved into some non-traditional areas along with some of the safety concerns for those working around this equipment. Codes and standards were discussed in general along with some issues that come about when over volt equipment is installed. This article will focus on some of the National Electrical Code requirements and common problems being experienced in the field today. Due to space limitations, not every aspect of high voltage installations can be covered in an article like this. Many of the problems seen and discussed in this article are due to lack of training and limited experience on the parts of the design engineers, electrical installers and inspectors.

Unit Descriptor. This Competency Standard Unit covers the development of appropriate protection systems for HV and LV distribution networks, including calculations of fault levels, selection of appropriate protection devices and automation requirements and protection coordination schemes. This also includes recommendations to support the calculations and must ensure conformance to specific organisational operational and system planning requirements, and compliance with national or supply authority codes. Application of the Unit. This Competency Standard Unit is intended to augment formally acquired competencies. It is suitable for employment-based programs under an approved contract of training. License to practice. Prerequisite Unit s. Where pre-requisite pathways have been identified.

Working Space for Electrical Equipment

Most power transformers use oil as an insulating and cooling medium but, where substations are located in restricted spaces, gas is used for this purpose. Gas insulated switchgear is commonly used in substations and the development of gas insulated transformers allows complete integration of substation equipment with resultant space and cost savings. Gas insulated transformers GITs have been in use since the s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. The main advantage of gas insulated transformers is that they are environmentally friendly and can be recycled easily.

This is an overview of general shop administration, available equipment, required operator adjustments, and equipment maintenance. Knowing the capabilities and limitations of the equipment before creating artwork is essential. Standard Drafting Practices And Theory. Industry standards for composition, geometric construction, general drafting practices, technical drawings, perspective projections, and parallel projections are foundational material on which all executionable practices rely.

§2700. Definitions.

A substation is a part of an electrical generation , transmission , and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

In an electric power system , switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches , mounted on insulating panels of marble or asbestos. Power levels and voltages rapidly escalated, making opening manually operated switches too dangerous for anything other than isolation of a de-energized circuit. Oil-filled switchgear equipment allow arc energy to be contained and safely controlled.

Electrical systems are typically given a great deal of consideration during the design and installation phase of new construction or major renovation, but very little thought after completion — until something fails. Even though our electrical systems are usually very reliable, it is likely that some components will need maintenance or testing at some point in the life of the building or structure. Therefore, the NEC contains requirements meant to allow for safe and practical access to electrical equipment after the time of installation. In the NEC , working space requirements are found primarily in Article

General Installation Requirements, Part XXV

Take a look inside. In the case of a blackout, the power supply needs to be restored quickly. Take the compact Oerlikon substation in Switzerland, for example, which takes up just 30 percent of the space required in the past. Is there such a thing as powerful overhead lines that also impress with design?
