Description

KEC115, KEC116 & KEC117

Generator Short Circuit & Over Current Protection, Output Relays and Optional Analog Output

  • Three phase Current Protection with VATOR, Definite time or Two level O/C trip function
  • “PREDICTOR” function, The Blackout Preventer
  • “Pathfinder” function eases fault finding
  • Independent ammeter with Full Load Current (FLC) mark on scale
  • Triple relay operation gives more flexibility
  • Built-in fast analogue Amp or Hz transducer (Optional)
  • Application
    The digitally controlled true RMS measurement on the KEC115x provides precision (1,0%) three phase current protection for AC generators, motors, transformers etc. for alarms or tripping of a non-essential load or breaker. It can also be supplied with a built-in current (KEC116x) or frequency transducer (KEC117x).
    The independent class 1,5 moving iron ammeter input (term. 26 & 27) MUST be externally connected or switched to read individual phase currents.
    User settable trip levels and delays. LEDs flash during countdown and indicate the alarm status. The “Pathfinder” function identifies the phase causing the trip by the flashing pattern of the LED.
    KEC115x is the standard range with relay outputs for over current and short circuit current trip. The highest phase current will activate the OC/SC levels.
    KEC116x range also include a fast response (<50mS) built-in Current transducer proportional to the HIGHEST phase current signal. This may be used as an input to a control system, to detect abnormal current conditions (loss of excitation etc).
    KEC117x range also include a fast response (<50mS) built-in frequency transducer. This may be used as an input to a control system.
    VATOR (VAriable Time Overcurrent Release function)
    Versions with VATOR function have definite trip time up to 150% generator over current load. Between 150-200% the trip time will be reduced dynamically based on a calculated curve to maintain thermal capability protection and selective protection between parallelled generators.
    Refer to the VATOR calculation excel sheet for further details of the time release curve.
    PREDICTOR
    The main feature of the Predictor function is to open bus-tie breakers or trip heavy loads to prevent a total blackout situation. The predictor relay(s) trips at set over current (O/C) or short circuit current (S/C) level, prior to the generator breaker trip. If the overload condition is still present after this load reduction the generator breaker will trip 1sec or 200mS later relative to set O/C or S/C time delays.
    The combination of VATOR and Predictor is the ultimate solution for electrical selectivity and thermal protection of parallelled generators.
    PATHFINDER
    The Pathfinder indicates the phase causing an over current or short circuit trip by the flashing pattern of the relevant LED. When either short circuit or over current trips have operated the relevant LED will flash in the following pattern to indicate the phase producing the trip.
    Unit meets IEC60092-504 and relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with Classification Societies requirements.
