  • Page 2: Safety Precautions

    Before using this product, please read this chapter carefully. This chapter describes the safety precautions recommended when using the optical interface unit type G1IF1. Before installing and using the equipment, this chapter must be thoroughly read and understood. Explanation of symbols used Signal words such as DANGER, WARNING, and two kinds of CAUTION, will be followed by important safety information that must be carefully reviewed.
  • Page 3 6 F 2 S 0 7 5 5 WARNING  Exposed terminals Do not touch the terminals of this equipment while the power is on, as the high voltage generated is dangerous.  Residual voltage Hazardous voltage can be present in the DC circuit just after switching off the DC power supply. It takes approximately 30 seconds for the voltage to discharge.

  • Page 5: Introduction

    In most situations the telecommunications equipment is remote from the protection equipment in the substation. The G1IF1 unit is normally located close to the multiplexer and may be up to 2km away from the GRL100 relay. The fibre optic cable must be either 50/125m (for distances up to 1km) or 62.5/125m (for distances up to 2km) and should be terminated with standard ST type...

  • Page 6: Description

    Code conversion is performed for connection to the CCITT-G703 or X.21 interface. G703 or X.21 is a synchronous interface, and provides a 64kHz timing signal, which the G1IF1 uses for synchronisation. The connections to the G703 or X.21 interface use balanced drivers and receivers in accordance with the G703 or RS422A/V.11 standard.

    However the G1IF1 can also be provided with dc 110/125V rating or dc 220/250V rating for 110/125V or 220/250V substation battery supplies. The connections to the G1IF1-01 are shown in Figure 3.2 (a), not including the test points. The figure also illustrates the functions of three removable links. The X.21 interface circuit is designed for 500V isolation against the rest of the system.

    (2) When the data transmission on fibre optic interface from the relay to G1IF1 is stopped: The LED “TX from RELAY” turns off and the send signal (the voltage between terminals TB1-6 and TB1-7) becomes “0V”.

  • Page 12: Installation

    4.3 Electrostatic Discharge CAUTION The printed circuit board (PCB) within the G1IF1 is not intended to be a removable module. Do not remove the PCB from the unit case, since electronic components on the PCB are very sensitive to electrostatic discharge. If it is absolutely essential to take the PCB out of the case, do not touch the electronic components and terminals with your bare hands.

  • Page 13: External Connections

    6 F 2 S 0 7 5 5 4.5 External Connections External connections to the G1IF1 are shown in section 3.2. There are three types of connection to the unit. The fibre optic connections are made with standard ST type connectors. Transmitters are of the LED type.

  • Page 14: Commissioning And Maintenance

    6 F 2 S 0 7 5 5 5. Commissioning and Maintenance 5.1 General The G1IF1 should be commissioned in conjunction with the GRL100 relay with which it is specified. Test personnel must be familiar with general relay testing practices and safety precautions to avoid personal injuries or equipment damage.

  • Page 15: Commissioning Procedure

    Ensure that all necessary communication connections are made at each end of the protection scheme. Apply auxiliary power to both GRL100 relays and to both G1IF1 units. Any failure in communication will be indicated by the GRL100 relays. If communication is healthy then proceed with commissioning of the GRL100 relays.
