1). What is an inverse time over current relay’s characterizing feature?The length of time that the relay operates will be reduced as the fault current increases.2). Mention the most important characteristics of relay contacts. A strong construction is required. Self-cleaning (oxides break-down quickly). Corrosion- resistantis a characteristic. Low contact resistance with no strictures and no bounces. Capable of transporting rated short-term current and also rated continuous current.3). Define p
