Introduction to Power Quality
CHAPTER 1 INTRODUCTION TO POWER QUALITY 1.1 INTRODUCTION This chapter reviews the power quality definition, standards, causes and effects of harmonic distortion in a power system. 1.2 DEFINITION OF ELECTRIC POWER QUALITY In recent years, there has been an increased emphasis and concern for the quality of power delivered to factories, commercial establishments, and residences. This is due to the increasing usage of harmonic-creating non linear loads such as adjustable-speed drives, switched mode power supplies, arc furnaces, electronic fluorescent lamp ballasts etc.[1]. Power quality loosely defined, as the study of powering and grounding electronic systems so as to maintain the integrity of the power supplied to the system. IEEE Standard 1159 defines power quality as [2]: The concept of powering and grounding sensitive equipment in a manner that is suitable for the operation of that equipment. In the IEEE 100 Authoritative Dictionary of IEEE Standard Terms, Power quality is defined as ([1], p. 855): The concept of powering and grounding electronic equipment in a manner that is suitable to the operation of that equipment and compatible with the premise wiring system and other connected equipment. Good power quality, however, is not easy to define because what is good power quality to a refrigerator motor may not be good enough for today‟s personal computers and other sensitive loads. 1.3 DESCRIPTIONS OF SOME POOR POWER QUALITY EVENTS The following are some examples and descriptions of poor power quality “events.” Fig. 1.1 Typical power disturbances [2]. ■ A voltage sag/dip is a brief decrease in the r.m.s line-voltage of 10 to 90 percent of the nominal line-voltage. -
Miniature Circuit Breakers, Isolators & Earth Leakage Units: Part 1
Electrical Miniature circuit breakers, isolators & earth leakage units: Part 1 Heading Here Hi I’m Bra Build• Click it to add text This week Clint is talking about electrical isolators & earth leakage units, explaining the basic applications & mounting options. Remember to use the correct load rated device for your application, ensuring the cable & equipment’s protection at all times. Note ! For the purpose of this presentation, we will be focusing on the miniature circuit breakers (MCBs), isolators & earth leakage units that are more commonly used in the modern day domestic/residential distribution board installations, however these devices are also used in commercial & industrial distribution boards & control panels. Lets Talk device mounting options Lets help you understand how the MCBs, isolators & E/L units are secured in an electrical DB or panel. Commonly used mounting options Electrical distribution board suited for Electrical distribution board suited for DIN mount devices SAMITE/MINI rail mount devices DIN rail SAMITE/MINI rail Important When selecting electrical equipment for a DB or panel installation, you will need to ensure that you select a device that has a mounting base compatible with the mounting rail in the DB or panel where the device is to be installed. Note! Sales staff need to be aware that when supplying a MCB intended to fit into an existing DB installation, although the din MCB may be a cheaper option, a din MCB is not always suitable for use in a mini rail DB & likewise the other way around. It’s always advisable to supply the customer with a MCB that matches the mounting rail currently installed in the customer’s DB. -

Rahi Chu Hydro Electric Project (25 Mw), Sikkim
RAHI CHU HYDRO ELECTRIC PROJECT (25 MW), SIKKIM EXECUTIVE SUMMARY LOCATION AND ACCESS TO PROJECT SITE Rahi Chu Hydo Electric Project with an installed capacity of 3 x 8.33MW is located in North Sikkim District of Sikkim and is proposed on river Rahi Chu, a tributary of Tolung Chu. The project site is located at about 197 km from Siliguri by road via Singtam & Mangan. Singtam is 100 km from Siliguri (on Siliguri-Gangtok NH-31A) & Singtam to Mangan is about 55 Km. The Diversion site is located at about 42 km from Mangan via Tung Bridge (on River Teesta) & Saffu village. The Diversion site is about 7 km from Saffu village on the Saffu-Sangkalan road presently under construction by BRO. Access road of about 8 Km will be required to be constructed from the Saffu- Sangkalan road to reach the Diversion site. HYDROLOGY The Rahi Chu, is a tributary of Tolung Chu, which in turn is a major tributary of the Teesta. The Rahi The catchment area up to the dam site is about 50 Km2 and lies between Longitude 88o32'25"E to 88o30'55"E and Latitude 27o32'58"N to 27o31'55"N. No site specific G&D data of Rahi Chu is available. Stream flow records (10-daily) of the Tolung Chu at the Sankalang gauge site (Catchment Area = 777 Km2) are available for the period May 1990 – Apr 2004). The flow series for the Panan Hydro-Electric Project was generated by applying a reduction factor of 0.89 on the observed stream flow series at Sankalang (1991-91 to 2003-04) with an annual runoff of 4140 mm, thus arriving at 3684 mm. -
Electrical – Wiring Methods, Components and Equipment for General Use
Electrical – Wiring Methods, Components and Equipment for General Use Approved for Public Release; Further Dissemination Unlimited At the completion of this unit you shall be able to: 1. Utilize section Z of the Safety and Health Hazard Inspection Program Checklist to identify compliant and non-compliant safety behaviors. 2. Identify areas of concern requiring immediate action to mitigate or prevent a possible injury. Please use “Slide Show” to properly view this presentation! • Let’s start with a discussion of Electrical Safety. Whenever you work with electrical devices there is a risk of electrical hazards, especially electrical shock. Risks are increased at maintenance and construction sites because many jobs involve electric power tools. Coming in contact with an electrical voltage can cause current to flow through the body, resulting in electrical shock and burns. Serious injury or even death may occur. Electricity has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and explosions. In 1999, for example, 278 workers died from electrocutions at work, accounting for almost 5 percent of all on-the-job fatalities that year, according to the Bureau of Labor Statistics. What makes these statistics more tragic is that most of these fatalities could have been easily avoided. • When an electrical shock enters the body it may produce different types of injuries. Electrocution results in internal and external injury to body parts or the entire body – often resulting in death. After receiving a “jolt” of electricity all or part of the body may be temporarily paralyzed and this may cause loss of grip or stability. -

How to Select an AC Power Supply by Grady Keeton
858.458.0223 | www.programmablepower.com White Paper How to Select an AC Power Supply By Grady Keeton Today’s electronic products must work under all types of The response of the AC power source to inrush current is conditions, not just ideal ones. That being the case, AC sources dependent on the method that the source uses for current- used in test applications must not only supply a stable source of limiting. AC power sources are designed to protect themselves AC, they must also simulate power-line disturbances and other from excessive loads current by either folding back the voltage non-ideal situations. (current limiting) or shutting down the output (current-limiting shutdown) and in many cases, this is user selectable. Fortunately, today’s switching AC power sources are up to the task. They offer great specifications and powerful waveform- In some instances, it may not be practical to have an AC source generation capabilities that allow users to more easily that can supply the full inrush current demanded by the load. If generate complex harmonic waveforms, transient waveforms, the test does not require the stress test from this current, it may and arbitrary waveforms than ever before. Some can even be possible to use the current-limiting foldback technique for provide both AC and DC outputs simultaneously and make these tests. AC motors can draw up to seven times the normal measurements as well as provide power. This level of flexibility operating current when first started. How long the motor will is making it easier to ensure that electronic products will work draw this current depends on the mechanical load and the under adverse conditions.
