  • Page 6 P50 Agile P15D 1 Introduction INTRODUCTION Features The P15D is a dual powered non-directional overcurrent and earth fault relay which provides protection for applications where no external auxiliary power supply is available, or where the auxiliary supply available does not guarantee the dependability required for protection applications. This relay is mainly deployed in industrial installations, distribution network substations and most specifically in Ring Main Unit (RMU) networks for monitoring and protection purposes.

  • Page 11 Pxxx Safety Information HEALTH AND SAFETY Personnel associated with the equipment must be familiar with the contents of this Safety Information. When electrical equipment is in operation, dangerous voltages are present in certain parts of the equipment. Improper use of the equipment and failure to observe warning notices will endanger personnel. Only qualified personnel may work on or operate the equipment.
  • Page 12 Safety Information Pxxx SYMBOLS Throughout this manual you will come across the following symbols. You will also see these symbols on parts of the equipment. Caution: Refer to equipment documentation. Failure to do so could result in damage to the equipment Warning: Risk of electric shock Earth terminal.
  • Page 13 Pxxx Safety Information INSTALLATION, COMMISSIONING AND SERVICING LIFTING HAZARDS Many injuries are caused by: ● Lifting heavy objects ● Lifting things incorrectly ● Pushing or pulling heavy objects ● Using the same muscles repetitively Plan carefully, identify any possible hazards and determine how best to move the product. Look at other ways of moving the load to avoid manual handling.
  • Page 14 Safety Information Pxxx Caution: NEVER look into optical fibres or optical output connections. Always use optical power meters to determine operation or signal level. Caution: Testing may leave capacitors charged to dangerous voltage levels. Discharge capacitors by rediucing test voltages to zero before disconnecting test leads. Caution: Operate the equipment within the specified electrical and environmental limits.
  • Page 15 Pxxx Safety Information Caution: Where UL/CSA listing of the equipment is not required, a high rupture capacity (HRC) fuse type with a maximum current rating of 16 Amps and a minimum dc rating of 250 V dc may be used for the auxiliary supply (for example Red Spot type NIT or TIA).
  • Page 16 Safety Information Pxxx PROTECTION CLASS 1 EQUIPMENT REQUIREMENTS Caution: Earth the equipment with the supplied PCT (Protective Conductor Terminal). Caution: Do not remove the PCT. Caution: The PCT is sometimes used to terminate cable screens. Always check the PCT’s integrity after adding or removing such earth connections. Caution: Use a locknut or similar mechanism to ensure the integrity of stud-connected PCTs.
  • Page 17 CT before opening any connections to it. Note: For most Alstom equipment with ring-terminal connections, the threaded terminal block for current transformer termination is automatically shorted if the module is removed. Therefore external shorting of the CTs may not be required.
  • Page 18 Safety Information Pxxx DECOMMISSIONING AND DISPOSAL Caution: Before decommissioning, completely isolate the equipment power supplies (both poles of any dc supply). The auxiliary supply input may have capacitors in parallel, which may still be charged. To avoid electric shock, discharge the capacitors using the external terminals before decommissioning.
  • Page 19 Pxxx Safety Information STANDARDS COMPLIANCE Compliance with the European Commission Directive on EMC and LVD is demonstrated using a Technical File. EMC COMPLIANCE: 2004/108/EC Compliance with EN60255-26:2009 was used to establish conformity. PRODUCT SAFETY: 2006/95/EC Compliance with EN60255-27:2005 was used to establish conformity. Protective Class IEC 60255-27: 2005 Class 1 (unless otherwise specified in equipment documentation).
  • Page 20 Safety Information Pxxx Equipment with this marking is not itself suitable for operation within a potentially explosive atmosphere. Compliance demonstrated by Notified Body Type Examination Certificate. ATEX Potentially Explosive Atmospheres directive 94/9/EC for equipment.

  • Page 203 Maintenance Maintenance checks In view of the critical nature of the application, Alstom Grid products should be checked at regular intervals to confirm they are operating correctly. The devices are self-supervising and so require less maintenance than earlier designs of protection devices.

Caution: Before carrying out any work on the equipment you should be familiar with the contents of the Safety Section or the Safety Guide Pxxx-SG-4LM-1 and the ratings on the equipment’s rating label.
  • Page 205 P50 Agile P15D 13 Installation Cleaning Warning: Before cleaning the IED, ensure that all AC and DC supplies and transformer connections are isolated to prevent any chance of an electric shock while cleaning. Only clean the equipment with a lint-free cloth dampened with clean water. Do not use detergents, solvents or abrasive cleaners as they may damage the product's surfaces and leave a conductive residue.
