  • Page 6: Introduction

    This Safety Guide also includes descriptions of equipment label markings. Documentation for equipment ordered from AREVA T&D is despatched separately from manufactured goods and may not be received at the same time. Therefore this guide is provided to ensure that printed information which may be present on the equipment is fully understood by the recipient.

  • Page 7: Symbols And External Labels On The Equipment

    Watchdog (self-monitoring) contacts are provided in numerical relays to indicate the health of the device. AREVA T&D strongly recommends that these contacts are hardwired into the substation's automation system, for alarm purposes. To ensure that wires are correctly terminated the correct crimp terminal and tool for the wire size should be used.
  • Page 8 Pxxxx/EN SS/E11 Safety Section Protection Class I Equipment Before energizing the equipment it must be earthed using the protective conductor terminal, if provided, or the appropriate termination of the supply plug in the case of plug connected equipment. The protective conductor (earth) connection must not be removed since the protection against electric shock provided by the equipment would be lost.
  • Page 9 Pxxxx/EN SS/E11 Safety Section Current transformer circuits Do not open the secondary circuit of a live CT since the high voltage produced may be lethal to personnel and could damage insulation. Generally, for safety, the secondary of the line CT must be shorted before opening any connections to For most equipment with ring-terminal connections, the threaded terminal block for current transformer termination has automatic CT shorting on removal of the module.

  • Page 10: Decommissioning And Disposal

    Pxxxx/EN SS/E11 Safety Section DECOMMISSIONING AND DISPOSAL De-commissioning The supply input (auxiliary) for the equipment may include capacitors across the supply or to earth. To avoid electric shock or energy hazards, after completely isolating the supplies to the equipment (both poles of any dc supply), the capacitors should be safely discharged via the external terminals prior to de-commissioning.

  • Page 11: Environment

    Pxxxx/EN SS/E11 Safety Section Environment The equipment is intended for indoor installation and use only. If it is required for use in an outdoor environment then it must be mounted in a specific cabinet or housing which will enable it to meet the requirements of IEC 60529 with the classification of degree of protection IP54 (dust and splashing water protected).

  • Page 27 If damage has been sustained during transit a claim should be made to the transport contractor and AREVA T&D should be promptly notified. Relays that are supplied unmounted and not intended to be installed immediately should be returned with their protective polythene bags.
  • Page 28 P12x/EN IN/A96 Handling, Installation and Case Dimensions Page 4/10 MiCOM P120/P121/P122/P123 HANDLING OF ELECTRONIC EQUIPMENT A person’s normal movements can easily generate electrostatic potentials of several thousand volts. Discharge of these voltages into semiconductor devices when handling electronic circuits can cause serious damage, which often may not be immediately apparent but the reliability of the circuit will have been reduced.

An example may occur in a cable with plastic insulation. In this application it is possible that the fault energy melts the cable insulation, which then reseals after clearance, thereby eliminating the cause for the fault.

  • Page 310 MODBUS DATABASE Page 4/248 MiCOM P120/P121/P122/P123 MODBUS PROTOCOL MiCOM P120, P121, P122 and P123 relays can communicate by a RS 485 link behind the unit following the MODBUS RTU protocol. Technical characteristics of the MODBUS connection 2.1.1 Parameters of the MODBUS connection The different parameters of the MODBUS connection are as follows: −...
  • Page 311 Writing of n words Presentation of the MODBUS protocol Master slave protocol, all exchange understands a master query and a slave response Frame size received from MiCOM P120, P121, P122 and P123 relays Frame transmitted by the master ( query): Slave number...
  • Page 312 When MiCOM P120, P121, P122 and P123 relays receive a master query, it validates the frame: If the CRC is false, the frame is invalid. MiCOM P120, P121, P122 and P123 relays do not reply to the query. The master must retransmit its query. Excepting a broadcast message, this is the only case of non-reply by MiCOM P120, P121, P122 and P123 relays to a master query.

This protocol is based on the VDEW communication protocol. The relay conforms to compatibility level 2, compatibility level 3 is not supported.

Private codes are not used, thus any events that cannot be passed using the standardised messages will not be sent.

  • Page 572 No response from MiCOM P120, P121, P122 and P123 relays when asked by the supervision software without any communication fault message. Cause: Mainly, this type of problem is linked to an error in the MiCOM P120, P121, P122 and P123 communication parameters. Action: Check MiCOM P120, P121, P122 and P123 communication parameters (data rate, parity, etc.) are in accordance with the supervision settings.
