Understanding Rectifier Circuits in Cathodic Protection Systems
Rectifier circuits in cathodic protection systems typically use 220V AC power input, though some companies may use 110V. The circuit includes a step-down transformer to lower the voltage, along with an AC breaker to protect the system. After passing through the diode stack for full-wave rectification, the rectified DC output is delivered to the system. The negative connects to the pipeline, while the positive connects to the anodes. A voltmeter is used across the shunt to measure current, ensuring the system operates safely and efficiently.
