All rights reserved. 4 5 Safety instructions Never work on the drive, the braking chopper circuit, the motor cable or the motor when input power is applied to the drive. After disconnecting input power, always wait for 5 minutes to let the intermediate circuit capacitors discharge before you start working on the drive, control cabling, motor or motor cable. Even when input power is not applied to the drive, externally supplied control circuits may carry dangerous voltages. Always ensure by measuring that no voltage is actually present. A rotating permanent magnet motor can generate a dangerous voltage. Lock the motor shaft mechanically before connecting a permanent magnet motor to the drive, and before doing any work on a drive system connected to a permanent magnet motor.

Brushless DC Electric Motor
Please read: A personal appeal from Wikipedia author Dr. Sengai Podhuvan We now accept ₹ (INR) Brushless DC electric motor From Wikipedia, the free encyclopedia Jump to: navigation, search A microprocessor-controlled BLDC motor powering a micro remote-controlled airplane. This external rotor motor weighs 5 grams, consumes approximately 11 watts (15 millihorsepower) and produces thrust of more than twice the weight of the plane. Contents [hide] 1 Brushless versus Brushed motor 2 Controller implementations 3 Variations in construction 4 AC and DC power supplies 5 KM rating 6 Kv rating 7 Applications o 7.1 Transport o 7.2 Heating and ventilation o 7.3 Industrial Engineering . 7.3.1 Motion Control Systems . 7.3.2 Positioning and Actuation Systems o 7.4 Stepper motor o 7.5 Model engineering 8 See also 9 References 10 External links Brushless DC motors (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors) are electric motors powered by direct-current (DC) electricity and having electronic commutation systems, rather than mechanical commutators and brushes. The current-to-torque and frequency-to-speed relationships of BLDC motors are linear. BLDC motors may be described as stepper motors, with fixed permanent magnets and possibly more poles on the rotor than the stator, or reluctance motors. The latter may be without permanent magnets, just poles that are induced on the rotor then pulled into alignment by timed stator windings. However, the term stepper motor tends to be used for motors that are designed specifically to be operated in a mode where they are frequently stopped with the rotor in a defined angular position; this page describes more general BLDC motor principles, though there is overlap. -

Failure Analysis of a Power Transformer Using Dissolved Gas Analysis – a Case Study
IJRET: International Journal of Research in Engineering and Technology eISSN: 2319-1163 | pISSN: 2321-7308 FAILURE ANALYSIS OF A POWER TRANSFORMER USING DISSOLVED GAS ANALYSIS – A CASE STUDY Ankush Chander1 Nishant2 1M. Tech Scholar, EEE Department Arni University Indora Himachal Pradesh, India 2Assistant Professor, EEE Department, Arni University Indora Himachal Pradesh, India Abstract Reliable and continued performance of power Transformer is the key to profitable generation and transmission of electric power. Failure of a large power transformer not only results in the loss of very expensive equipment, but it can cause significant guarantied damage as well. Replacement of that transformer can take up to a year if the failure is not disastrous and can result in tremendous revenue losses and fines. A Power Transformer in operation is subjected to various stresses like thermal stress and electrical stress, resulting in liberation of gases from the hydrocarbon mineral oil which is used as insulant and coolant. Dissolved Gas Analysis is a technique used to assess incipient faults of the transformer by analyzing specific dissolved gas concentrations arising from the deterioration of the transformer. DGA is used not only as a diagnostic tool but also to track apparatus failure. In this case study the fault and defects that occurred in 400kV/220kV/132kV/66kV Sub Station can be found by DGA. Keywords: Power Transformer, Dissolved Gas Analysis, ----------------------------------------------------------------------***---------------------------------------------------------------------- 1. INTRODUCTION Table 2.1 Failure Mode of Transformer A power transformer is one of the most important and costly Description Failures Duration devices in electrical systems. Its importance is attributed No % TTF ATF directly to the continuity of power supply, since its loss through failure or defect means a supply stoppage. -
Preventive to Predictive
Preventive to Predictive The future of Transformer Oil Testing By William Morse Morgan Schaffer Inc. Presented at AVO New Zealand’s 2001 International Technical Conference April 3-5th, 2001 Morgan Schaffer Inc. 5110 Ave de Courtrai Montreal, Quebec, Canada H3W 1A7 Tel: ++514-739-1967 Fax: ++514-739-0434 Web: www.morganschaffer.com Preventive to Predictive, the Future of Transformer Oil Testing Transformers form a critical part of our electrical world. Without them we would not be able to transmit and distribute electricity generated at remote power stations. Over time transformers fail which can be costly not only to the utility or owner of the transformer but the consumer as well. Oil is used as an insulator and a coolant in transformers and by monitoring its condition the transformer’s overall health is determined. This paper will discuss the importance of routine testing of transformer oil and what role it plays in a preventive maintenance program. Living in Canada or the US we have been educated in the importance of routine testing of expensive equipment. Even in our personal lives we make sure that we routinely change the oil in our cars. If we didn’t the engine would seize and we wouldn’t be able to go anywhere. In the past not much was known about the interaction of the components within a transformer. Electrical engineers understood the need for the different components but not what happens when something goes wrong or fails. Early designers of transformers thought that since there were no moving parts, transformers would never fail.
