A transmission line fault generates transient high frequency travelling waves (TWs) that propagate through the entire network. The location can be determined by recording instants at which incident arrive various points in In single end-based methods, wave arrival time and its subsequent reflections from point are used to identify location. heavily branched distribution networks, magnitude of t...

This paper describes the synchronized PWM techniques based on space vector approach for three level voltage source inverters. The objective is to improve the output waveform of the inverters used in high power applications, where the switching frequency is very low. This is achieved by maintaining the synchronization and half wave symmetry, quar ter wave symmetry, threephase symmetry in the PWM...

Out of the various existing ultrasonic power measurement techniques, the radiation force balance method using microbalance is most widely used in low power (below 1 W) regime. The major source of uncertainty associated with this technique is the error in ac voltage measurement applied to the transducer for the generation of ultrasonic waves. The sources that deteriorate the ac voltage measureme...
