Power System Stability and Control
List Price: $105.00
Sale Price: $75.75
|
|

Voltage stability is a major concern in the planning and operation of electric power systems. This is the first book to provide a clear, in-depth explanation of voltage stability, covering both transient and longer-term phenomena and presenting proven solution to instability problems. An essential tool for all electric power and utility engineers, the book describes equipment characteristics for transmission, generation, and distribution/load subsystems of a power system, together with methods for the modeling of equipment. Readers will find static and dynamic computer simulation examples for both small equivalent power systems and for a very large power system, plus an account of voltage stability associated with HVDC links. They will also get helpful planning and operating guidelines, computer methods for power flow and dynamic simulation, and descriptions of actual voltage instability incidents.

Sets forth the steps needed to protect critical telecommunications circuits from power faults and lightning in high voltage environmentsThe need to protect telecommunications circuits from power faults and lightning has never been greater: when power outages or system disturbances occur, reliable telecommunications are essential. With this book as their guide, readers will know what they need to do (and not do) to protect critical telecommunications circuits and equipment located in high voltage environments such as electrical power plants, substations, and power towers. Moreover, the book explains how to get the job done safely, detailing the proper implementation of safety procedures and the use of protective equipment to eliminate or minimize risk.Setting the foundation, the book begins with an overview of the problem, key issues, industry standards, and safety concerns. Next, it covers: Definitions and fundamentals of electric power systems, with regard to HVPT applicationsCauses, boundary conditions, and calculations of ground potential riseCritical telecommunications circuits that must be protected in high voltage environmentsProtection schemes and equipment to resolve groundpotential rise problemsEffective installation and testing of high voltage interface equipmentPersonal safety for telecommunications personnel working with equipment in high voltage environmentsThroughout the book, the author refers to accepted industry standards and best practices. Written by one of the most respected professional trainers in the telecommunications industry, High Voltage Protection for Telecommunications can be used for professional training courses or self-study. It will enable readers to protect critical data and voice communications circuits from high voltage events and protect themselves during equipment installation and maintenance.

Easy Method To Connect Diodes In Series And Parallel To Get The Desire Specification
Troubleshooting tough dog (difficult to repair) problems consumed you lots of time and another problem that take you lots of time is to locate the original spare part numbers. You may take couple of minutes to find a bad components but because of no spare parts available in your component’s compartment, then you will need some extra time to find it such as to call up your electronic suppliers, finding your semiconductor data book for specification and replacement, searching the internet for the particular component data hope to get an exact substitution and some of you may visit forum to ask for an answer.
This little ‘extra time’ sometimes may take you longer than an hour. Forums usually take couples of hours to days to give you the answer. Worst case, if there are no answer from the forum and the equipment you repair lying down the corner of the technical department waiting for you to settle it-sound familiar? Even if your electronic suppliers have the part, you will again wasting your time purposely drive to town just to get that part only. If your customer can wait then there will be no problem and what if the customers want it fast?
In today’s article I’m going to show you how you can use diodes to connect either in series or parallel to get the desire volts and ampere for replacement assuming that there is no way you can find the original part number.
When talks about diode specification, one always refer to peak reverse voltage (PRV) and ampere (A). Assuming you have a diode with the spec of 800V 2A and you want to find a replacement. You can always use diodes connect in series method to get the desire spec. For example, two 400V 2A diodes connect in series will get you 800V 2A. You can always use this method for replacement but to make the diodes last longer you have to connect a resistor and a capacitor and place across each diode to equalize the PRV drops and guard against transient voltage. In order to find the resistor value, as a rule of thumb, multiply the PRV rating of the diodes by 500 ohms. For example, an 800 PRV diode should be shunted by 800 X 500 equal to 400,000 ohms. As for the capacitor value, use a 0.01 microfarad ceramic disc capacitor connected across each diode.
Now, if you have a 400V 10A diode that needs replacement, you may use the diodes connect in parallel method to get the desire spec. Connect two 400V 5A in parallel and you will get 400V 10A. From experienced, if possible try to find or get the exact or equivalent part number first before using the above method.
