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.

at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
