Built-in capacitive voltage divider voltage transformer, which directly outputs standard small voltage signals, simplifies the system structure, reduces error sources, and improves the stability and accuracy of the entire measurement system;
The built-in current sensor has a wide frequency range, a large measurement range, good linearity, and strong anti-interference ability, which can make the protection device operate reliably under system fault conditions;
No overcurrent will be generated when the voltage output terminal is short-circuited twice, there is no hidden danger of ferromagnetic resonance failure, which has better equipment safety;
The first and second fusion solid-sealed poles are highly integrated, small in size, light in weight, and low in energy consumption, suitable for highly integrated applications in intelligent distribution networks
