Covered Conductor Burn-Down Phenomena in Indonesia without Protection Relay Operation

Wave Propagation Characteristics on a Covered Conductor

A wave propagation characteristic is very significant to investigate a transient voltage and insulation design of a cable. This paper carries out an experiment and a simulation of wave propagation characteristics on an insulation covered conductor in comparison with a bare conductor. The simulations are carried out using Electro Magnetic Transient Program (EMTP) and Finite Difference Time Domai...

Digital Communications for Relay Protection

Electric utilities are expanding communications infrastructure due to increased need for information. Due to performance, price, and technological advances, digital communication systems are frequently chosen as this multiple user data network. This two-part paper describes the application of digital communication in power system protection. Part 1 describes the digital communications architect...

Corneal Protection for Burn Patients

Burn during a routine pterygium excision operation.

PURPOSE To report a patient who sustained a spark fire burn during a routine pterygium operation. METHODS A 40-year-old woman was referred for pterygium excision in her left eye. During the operation a low temperature cautery caused a spark fire that resulted in left eye corneal burn, upper and lower eyelid burns, and melting of eyelashes and eyebrows bilaterally. RESULTS Topical antibiotic...
