Motor phase, type of motor,voltage rating, type of
connection (star/delta), Maximum current, operating
frequence, tolerance level, class of insulation, serial no,
design code, thermal resistivity, operating temperature,
class of frame, rated KW,power factor

why protection and metering CT's are always connected in star why not in delta?

what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.
