AFDD (ARC FAULT DETECTION DEVICES) is designed to protect the electric, and dynamic detect any dangerous arc .AFDD Effective works in circuit of the grounding,series and parallel arcing series and parallel arcing and detect and distinguish between dangerous and working arcs . when the fault arc occurs, AFDD can find it out and send a signal to automatically trip a circuit in order to prevent from an electrical fire.
GDIS is designed for protecting DCS ( distributed control system ) and PLD (programmable logic controller), it broadly heightens the safety of important control system through suppressing interruption derived from ground potential rising.It is suitable for the key sensitive control equipment (such as DCS, PLC) in continuous production process, effectively preventing the high frequency interference of the ground network,suppressing the secondary equipment interference caused by ground potential counterattack, ground overvoltage, etc., reduce the risk of comprehensive automation control system, Instrument malfunction and measurement error.Effectively isolate network interference, reduce the risk of interference with the control system, prevent unplanned stop due to a local ...
