Low-voltage Pole-mounted Circuit Breakers Must Ensure The Reliable Operation Of A Large-area Power Grid.

For the power grid, the performance stability of the Lv Pole Mounted Circuit Breakers is closely related to the reliability of its thermal trip unit or overcurrent protection mechanism. If their overload protection response time gradually deteriorates with the extension of service life, it may lead to delayed operation or failure to operate, thus threatening the stability of power distribution.

Therefore, when using POPs as branch point equipment in the distribution network, their selection and maintenance strategies must comply with the overall architecture design requirements of the distribution network. Regularly monitoring their overload protection characteristics and electrical performance status is of great significance for maintaining the stable operation of the power grid system.
