The wiring is to be considered as an example for the default configuration and operation mode with 1 common trip output.

  • Page 13: Configurability

    Configurability One of the key features of InteliPro unit is high level of flexibility and adaptability of the system to the particular application. The way how to achieve this is the configuration. Use LiteEdit PC software to read the configuration from the controller or disk, view it, modify it and write the configuration to controller or disk.

    In any case, it must be assured that the InteliPro relay has full control at opening the appropriate breaker by the trip command - i.e. in case of Trip state the unit receives the appropriate CB feedback, confirming its open position.

  • Page 22: Operation Mode With 2 Trip Outputs

    2 are available. • For each protective function in InteliPro, it is possible to assign either Trip 1 or Trip 2 function, none of them, or both. The setpoint xxx Trp BO in the appropriate group of protection setting is used for this assignment.

  • Page 23: Trip And Fault Reset Description

    The function is compatible with IG/IS-NT controllers. CAN2 interconnection between the gen-set controllers and InteliPro is necessary to allow this feature. Use the LiteEdit configuration window to configure the appropriate binary and analog values to be transmitted from InteliPro via the CAN2 button.

  • Page 25: Protective Functions

    In order to e.g. activate only one adjustable pickup used within a multiple-stages protective function, set this pickup limit to zero. E.g. InteliPro allows setting 2 stages of overvoltage protection. To use only V> and block the V>> stage, set the pickup limit V>> to 0V. In general, setting of any pickup limit of any protective function blocks this protection stage.

  • Page 26: Protective Functions In Detail

    V Unb: V Unb. It refers to the amplitude unbalance of the measured voltage. "Loss of mains" protections InteliPro provides two different methods for fast evaluation of loss of mains (LOM), into which the generator operates: Vector shift Rate Of Change Of Frequency The loss-of-mains protections setting is done using the setpoints in the group LOM.

  • Page 27: Rate Of Change Of Frequency (Df/Dt, Rocof, Ansi 81R)

    (loss of mains), which is normally capable of keeping the frequency on a stable level. The frequency change is expressed as tangent in time [Hz/s]: InteliPro, SW version 1.0, ©ComAp – May 2011 InteliPro Application Guide...

  • Page 28: Overcurrent: Definite-Time, Idmt And With Voltage Control

    It is a fast protection, similar to Vector shift, however, unlike Vector shift, which detects immediate phenomena, the tangent calculation requires a certain time for evaluation. In ComAp protection relays, the evaluation time for ROCOF protection can be adjusted in number of sine curve cycles being taken into evaluation from 1 to tens of cycles (each having 20ms).
