Convergence problems and loss of accuracy due to numerical ill-conditioning is a frequently encountered problem in power system state estimation. It has been experienced by the researchers that the presence of PMU measurements along with the conventional measurements deteriorates the numerical conditioning of the so-called hybrid state estimator. This paper describes a simple technique to analyze...
This paper describes power quality audits conducted at hospitals in India. Voltage, current and power measured at various points were used to assess the quality of the power. The main power quality problems found in hospitals were voltage flicker, neutral currents, and harmonic distortion (THD) value. Measurement, analysis and conditioning of power quality has been studied in few different hospitals...
In this paper a study has been carried out to use solar cell as a simple static transducer for measurement of linear and angular displacement of a moving object as a primary parameter and also it can be extended for its derivative parameter like velocity, acceleration etc. The working principle of solar cell and its scope of working as a transducer have been discussed. Experimental investigation through...
