    1.1 The basic configuration RCS-9611B is applicable to the protection, measurement and control of the feeder line in the low current grounding system (neutral point ungrounded or grounded through arc suppression coil system) with a voltage level below 35kV and the neutral point grounded through resistance. It can be installed in panel assembly or locally in the switchgear. (1) Main functions of protection a) Three section fixed time limit directional overcurrent protection that can be locked by low-voltage (the third section can be set as inverse time limit, and three inverse time limit characteristics can be selected, and the inverse time limit can also be locked by direction or low-voltage); b) Three section zero sequence overcurrent protection (zero sequence current can be applied externally or from

    1.4 Measurement and control and other functions 1.4.1 Measurement and control function a. Telemetry is mainly used to measure voltage, current, zero sequence current, active power, reactive power, power factor, frequency, etc., and can calculate active and reactive electrical degrees. According to the number of connected measuring current channels, you can set whether to use the two meter method or the three meter method to measure power in the "operating parameters". b. Calibration of measuring channel 1) External AC terminal wiring: measuring current (including phase current and zero sequence current) circuit terminals are connected in series and voltage terminals are connected in parallel (PSP641U requires three-phase symmetrical voltage). 2) Offset calibration: external AC terminal
