Problems of electrical equipments generally arise due to over heating from loose connection and/or poor connection. To avoid this, an electrical flashover monitor protects and monitors the loose connections by means of a set of sensors (2) fixed near/inside the equipment (1). Temperature thus sensed is fed to a micro processor (4) based software driven programmable temperature data logger/scanner which gives continuous display (5) of the temperature monitored. When the temperature exceeds the preset value, which is more than the maximum temperature attained by the monitor device when the ambient temperature is maximum and rated maximum permissible current is flowing through the equipment (1) an alarm is initiated so that corrective action can be initiated.
