    Protection and control

    F650 provides fast protection and control for feeder management and spacing control, including:

    Over current protection

    Transient and time-lapse function can be used for phase, neutral, ground/sensitive grounding, and the delayed flow function can be used in negative sequence current. Provides a variety of time curves, including IEEE/ANSI, IECA/B/C/long inverse time/short inverse time, GE IAC, I2t, fixed time, rectifier curve and four user programmable curves.

    Direction element

    For phase, neutral, grounding and sensitive grounding current, directional function is available. The neutral/grounding directional elements can be programmed to work in zero sequence voltage, grounded sensitive current or double polarization conditions.

    Voltage protection

    Provide phase/auxiliary overvoltage, undervoltage, neutral and negative sequence overvoltage protection.

    Frequency components

    Three separate frequency units can be set up to be used for or over frequency protection, usually for load shedding.

    Circuit breaker failure

    Use circuit breaker failure function to determine that the tripping order sent to the circuit breaker has not been implemented in the specified time delay. In case of failure of the circuit breaker, the device will send another tripping signal to the circuit breaker, which is the voltage source of the fault current. The F650 includes two levels of current and two levels of delay, one without the use of current components, and an internal pull arc current detection element. There are three levels of circuit breaker failure elements: "heavy tripping" or "surveillance" to make a re-trip signal to the relevant circuit breakers that have already executed the initial trip instructions;" High "and low" to perform complex protection schemes. This function can be started/locked by digital input and communication.

    Automatic reclosing

    This function can be used in three-phase trip and single circuit breaker. Before locking, the relock can be used for 4 times. Each lock can be set independently. The automatic reclosing output can be used to modify the circuit protection Settings between the gates.

    At the same time to check

    The F650 is equipped with a period checking element. The algorithm of the protection element allows circuit breaker closing time compensation to obtain the optimum closing conditions. The components (Δ V) monitoring voltage amplitude and phase Angle (Δ phi) and frequency (Δ f) the biggest difference, and power conditions.

    Multi-set value setting group

    Three separate protection setting sets can be stored in F650 non-volatile memory. The user can enter and communicate via the contact, and the internal or external editor is in the active state setting value.
