An Efficient Algorithm for Partial Discharge Localization in High-Voltage Systems Using Received Signal Strength

Emitter localization using received-strength-signal data

This paper considers a scenario in which signals from an emitter at an unknown location are received at a number of different collinear locations. The receiver can determine the received signal strength, but no other parameters of the signal. Postulating a log-normal transmission model with a constant but unknown path loss exponent and, also, an unknown transmit power and known noise variance, ...

Partial Discharge Detection and Localization in High Voltage Transformers Using an Optical Acoustic Sensor

A partial discharge (PD) is the dissipation of energy caused by the buildup of localized electric field intensity. In high voltage devices such as transformers, this buildup of charge and its release can be symptomatic of problems associated with aging, such as floating components and insulation breakdown. This is why PD detection is used in power systems to monitor the state of health of high ...

Learning Indoor Localization using Radio Received Signal Strength

Accurate and simple source localization using differential received signal strength

Locating an unknown-position source using received signal strength (RSS) measurements in an accurate and low-complexity manner is addressed in this paper. Given that the source transmit power is unknown, we employ the differential RSS information to devise two computationally attractive localization methods based on the weighted least squares (WLS) approach. The main ingredients in the first al...

Partial discharge signal detection using ultra high frequency method in high voltage power equipments: a review

Partial discharge (PD) can be detected using ultra high frequency (UHF) method to increase the detection threshold and to improve the performance of on-line measurement of PD in noise environment. The PD emitted energy as electromagnetic emission, acoustic emission and ozone and nitrous oxide gases. We can use this emitted energy to detected PD signal. The best method to detect PD in gas insula...
