Eliminate noise interference

Display stable readings

Digital Processing

A built-in microcontroller calculates the effective voltage value (RMS value in AC systems) and updates the display in real time.

How Current Is Measured

Current Sensing Methods

Dual-display protectors typically use one of the following methods:

Shunt resistor method (measuring voltage drop across a resistor)

Current transformer (CT) method (common in AC systems)

Hall effect sensor (used in more advanced models)

Signal Conditioning

The raw current signal is usually very small or unstable, so it is:
