Chapter 1 The History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers

The cardiovascular system consists of : heart (심장)‚ and vessels (혈관)‚ arteries (동맥)‚ capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs‚ alveolar capillaries‚ and pulmonary veins

INTRODUCTION When the machine fails or break down‚ the consequences can range from annoyance to financial distortion‚ personal injuries and possibly the loss of life. For this reason‚ the early detection‚ identification and correction of machine problems paramount to anyone involved in the maintenance of industrial machinery to ensure continuous‚ safe productive operation. The use of machinery vibration and the technology advances that have been developed over the years make it possible to not

and trace how the cardiac impulse travels through the myocardium. 19. Name the common term for the sinoatrial (SA) node. 20. Discuss the physiological stages of cardiac muscle contraction and trace how they appear on graph plotting mV vs. time. 21. Explain why the refractory period between cardiac muscle contractions is so long. 22. Trace a typical ECG and label each wave or complex and explain what event of the CCS corresponds to each wave. 23.

Power-Transmission System Using Near-Field Coupling Wireless power transmission is the transmission of electrical energy from a power source to an electrical load without man-made conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. So a study was made on the investigation of wireless power transmission by near-field coupling from the view point of the antennas. Mainly the antennas are of two types

density but better efficiency than induction motor Slightly lower power factor Sensorless control is much easier due to motor saliency. 8. What are advantages of syrm over pm machine? More reliable than PM machine There need not be any excitation field as torque is zero‚thus eleiminating electro magnetic spinning losses. 9. What are applications of syrm? Synthetic fiber manufacturing equipment Wrapping and folding machine Auxiliary time mechanism Synchronized conveyors Metering
