Power Consumption of a Cathodic Protection Rectifier

Rectifiers require AC power to drive the cathodic protection system on a 24-hour basis. High resistance ground beds can drive up the cost of AC power.

Rectifier power consumption is calculated,

P = 1.5E_RI_R

𝑃 — Power consumption per month(kWh)

𝐸_𝑅 — Rectifier output voltage(V)

𝐼_𝑅 — Rectifier current output(Amps)

MB = PU_r

𝑀𝐵 — Monthly bill(Dollars)

𝑈_r — Utilities rate($/kWh)
