    APPENDIX B APPENDIX B MODEM CONNECTION If we wish to connect the relay to a remote PC, it will be necessary to previously link two modems to the telephone line. The modem on the relay side will receive the call, and the modem on the PC side will make the call. This way, both modems will be configured in different ways: the modem on the PC side will receive the commands from the PC for starting or ending communication, and therefore it will make the call.

    B.1 HAYES MODEM APPENDIX B B.1HAYES MODEM In order to establish communication between two HAYES modems, both of them must accept HAYES commands. This is compulsory, as the PC will send specific commands for this type of modem. We must place the AT command before every command.

    APPENDIX B B.2 V.25BIS MODEM B.2V.25BIS MODEM ENERVISTA MII SETUP software allows the modem making the call to accept V.25bis commands. In this case, the modem on the relay side could be either HAYES or V.25bis, as it will not need to process any relay command. The configuration of this kind of modem is performed by means of microswitches that set its operation.

    APPENDIX C C.1 GENERAL PRINCIPLE OF OPERATION APPENDIX C HARMONIC FILTERINGC.1GENERAL PRINCIPLE OF OPERATION The present document intends to give an overview on how the MIB relay deals with analog signals, in order to help determine whether the relay is appropriate for certain applications. MIB relays, as the rest of our digital relays, are based on the following functional diagram: Figure C–1: Each of these blocks has its own functionality inside the general operation of the unit, as follows:...

    C.2 DIGITAL FILTER APPENDIX C C.2DIGITAL FILTER The first operation performed by the CPU with the voltage and/or current signal samples is the DFT. The Discrete Fourier Transformation consists in decomposing a signal into a series of sinusoidal signals with frequencies that are multiples of the fundamental frequency.
  • Page 174 APPENDIX C C.2 DIGITAL FILTER Figure C–4: can experience small variations for frequencies that are not the fundamental and its harmonics, as the measure varies for these frequencies. As an example, we can see in the next figure how a relay measure varies when it is set to 50 Hz, and it is being applied 60 Hz.

    C.3 MEASURE AT FREQUENCIES BELOW THE RATED FREQUENCY (FREQUENCY TRACKING) APPENDIX C C.3MEASURE AT FREQUENCIES BELOW THE RATED FREQUENCY (FREQUENCY TRACKING) As already mentioned, the digital filter is related to the fundamental frequency, so higher multiple frequency values are annulled During the start-up of generators, the voltage frequency in terminals and currents that can appear in the event of a fault, will depend on the machine speed.
