Power Measurement using CT & PT
Power Measurement using CT & PT
Product Code : 46607
Brand Name : Tesca
Product Description
46607 Power Measurement using CT and PT setup is designed to explore the measurement techniques used in electrical meters for measurement of Voltage, Current, Power etc. Current Transformer (CT) and Potential Transformer (PT) are used to sense Current and Voltage respectively from a transmission line. The various parameters that affect the Current and Voltage sensing using CT and PT are primary and secondary winding turns, gauge of wire and type of core. 46607 provides indepth explaination and experimental analysis of various configurations of Current and Voltage measurement using CT and PT                                                                                                                                                                                                                                                                                                                                                       
The students can measure the Voltage, Current, Wattage and Power Factor. Digital Voltmeter, Ammeter and Wattmeter are provided on panel to increase accuracy of measurement. The meters have very high accuracy and resolution.                                                                                                                                                        
                                                                                                                           
The CT is provided on panel so that students can change the turns in primary winding and measure the corresponding changes in secondary winding and change in measurement. Protection circuit is inbuilt.
