🔍 Key Concepts

• Impressed current cathodic protection (ICCP) system operation as shown in EL-0090 • Role of reference anodes versus protective anodes in feedback control • What an electronic regulator normally does with a set point signal and a feedback signal

💭 Think About

• Look at which components are physically wired into the electronic regulator box in the illustration—do you see connections from the reference anodes, from the set‑point adjustment, or from the control amplifier output? • Ask yourself: which current in this system actually needs tight automatic regulation to protect the hull—the tiny reference anode current or the larger protective anode current? • Consider how an automatic control loop works: what two quantities are compared, and what device adjusts the output to keep the system at the desired value?

✅ Before You Answer

• Verify from the diagram which device the reference anodes connect to directly (through the Ref. Anode Sel. Sw.). • Verify which component is between the electronic regulator and the rectifier bridge that feeds the protective anodes (hint: look at the control amplifier). • Check which answer choice correctly describes a loop using set point potentiometer + reference anode signal → electronic regulator → control amplifier → protective anode current.

What is the purpose of the electronic regulator as shown in the illustration? See illustration EL-0090.

It receives an input from the control amplifier as well as the set point potentiometer and the output controls the reference anode current.

It receives an input from the control amplifier as well as the reference anode and the output controls the set point value.

It receives an input from the set point value potentiometer as well as the reference anode and the output controls the protective anode current via the control amplifier.

It receives an input from the set point potentiometer and the output controls both the reference anode current and the protective anode current.
