what is the advantage of Cathodic eathing system and what
is the basic principle and how itis working, please explain
clearly .
Answer Posted / william lobo
cathodic protection systems are two types one is ICCP i.e.
Impressed Current Cathodic protection and the other is
sacrificial Anode Protection system.
Sacrificial anode ytpe cathodic protectionsystems provide
cathodic current by galvanic corrosion. The curent is
generated by metalically connecting the structure to be
protected to a metal/alloy that is electrochemically more
active than the material to be protected. (Both the
structure and the anode must be in contact with the
electrolyte.) Current discharges from the expendable anode,
to the electorlyte and onto the structrue to be protected.
Special backfill mateiral can also be used.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
