Temperature Rise During Short Circuit

During a short circuit there will be electromagnetic forces which determine the required busbar size and the support size. In addition to that we need to be careful about the extreme overheating of the busbars due to the high current, which leads to softening of the material and damage to the support structure.   At […]

Temperature Rise in Electrical panel boards

METHOD TO ASSES THE TEMPERATURE RISE INSIDE A LOW VOLTAGE PANEL BOARD  INTRODUCTION In order to assess the temperature rise of the air inside the low voltage panel board, a method is proposed in IEC 60890 ( A method of temperature-rise assessment by extrapolation for partially type- tested assemblies ( PTTA ) of low-voltage switch […]

Maintaining the Reliability of an Electrical System for Fire Pumps

Abstract – Protection from fire hazards is a combined effort of studying and practicing the techniques which are used to mitigate the destructive effects of an unintended fire in a property. In order to minimize the damage created by these fire hazards, the protection system should be erected according to the respective laws and guidelines regarding […]
