Phase Sequence With FR-02
18 September, 07:09
FR-02 phase sequence relay controls the order of the 3 phases feeding motors.
Thanks to phase failure feature, FR-02 switched the output relay OFF in case of a fault in any of the phases.
In order to uncorrect order of R,S,T phases, FR-02 switches the output relay OFF.
FR-02 detects the break of the neutral connection and cuts the supply to protect the system.
