the voltage between structure & soil should be maintain
about -1.12 volts w.r.t reference cell,according to
(NACE STANDARD).Equipments used in CP system:-1)Zinc Anodes
in sacrificial type
2)Anodeflex in Impressed type
3)Reference cells - CuCu-So4
4)Transformer Rectifier unit (Rating 50V/50A DC output)
5)Thermit weld
4)connecting wires
5)Anode & Cathode Juntion Box (A&CJB)
6)Reference cell junction Box(REJB)
7)Test Lead Point (TLP)
