  • Page 12 Chapter 2 - Safety Information P50 Agile P153 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.
  • Page 13 P50 Agile P153 Chapter 2 - Safety Information 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...
  • Page 14 Chapter 2 - Safety Information P50 Agile P153 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 15 P50 Agile P153 Chapter 2 - Safety Information Caution: Disconnect power before disassembling. Disassembly of the equipment may expose sensitive electronic circuitry. Take suitable precautions against electrostatic voltage discharge (ESD) to avoid damage to the equipment. Warning: NEVER look into optical fibres or optical output connections. Always use optical power meters to determine operation or signal level.
  • Page 16 Chapter 2 - Safety Information P50 Agile P153 EQUIPMENT CONNECTIONS Warning: Terminals exposed during installation, commissioning and maintenance may present a hazardous voltage unless the equipment is electrically isolated. Caution: Tighten M4 clamping screws of heavy duty terminal block connectors to a nominal torque of 1.3 Nm.
  • Page 17 P50 Agile P153 Chapter 2 - Safety Information Warning: The PCT is sometimes used to terminate cable screens. Always check the PCT’s integrity after adding or removing such earth connections. Warning: Use a locknut or similar mechanism to ensure the integrity of stud-connected PCTs.
  • Page 18 Chapter 2 - Safety Information P50 Agile P153 Caution: Check integrity of the PCT connection. Caution: Check voltage and current rating of external wiring, ensuring it is appropriate for the application. PERIPHERAL CIRCUITRY Warning: Do not open the secondary circuit of a live CT since the high voltage produced may be lethal to personnel and could damage insulation.
  • Page 19 P50 Agile P153 Chapter 2 - Safety Information Warning: Data communication cables with accessible screens and/or screen conductors, (including optical fibre cables with metallic elements), may create an electric shock hazard in a sub-station environment if both ends of the cable screen are not connected to the same equipotential bonded earthing system.
  • Page 20 Chapter 2 - Safety Information P50 Agile P153 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.

    P50 Agile P153 6 Protection Functions PROTECTION FUNCTIONS Overcurrent Protection Principles Most power system faults result in an overcurrent of some kind. It is the job of protection devices, formerly known as relays but now known as Intelligent Electronic Devices (IEDs), to protect the power system from such faults.

    P50 Agile P153 6 Protection Functions Another possible situation where the timer hold facility may be used to reduce fault clearance times is for intermittent faults. An example of this may occur in a plastic insulated cable. In this application it is possible for the fault energy to melt and reseal the cable insulation, thereby extinguishing the fault.

    P50 Agile P153 6 Protection Functions • Line to Line to Earth (accounting for approximately 5% of all faults) • Line to Line to Line (accounting for approximately 2% of all faults) Although not as common as earth faults (single line to earth), phase faults are typically more severe. An example of a phase fault is where a fallen tree branch bridges two or more phases of an overhead line.

  • Page 158: Negative Sequence Overcurrent Protection Implementation

    P50 Agile P153 6 Protection Functions However, certain faults may arise which can remain undetected by such schemes. Negative Sequence Overcurrent elements can be used in such cases. Any unbalanced fault condition will produce a negative sequence current component. Therefore, a negative phase sequence overcurrent element can be used for both phase-to-phase and phase-to- earth faults.

    P50 Agile P153 6 Protection Functions The fact that both EF1 and EF2 elements may be enabled at the same time leads to a number of application advantages. 2.4.2 Earth Fault Protection Logic The Earth Fault current is compared with a set threshold (IN1>(n) Current Set) for each stage. If it exceeds this threshold, a Start signal is triggered, provided there are no blocks.

If the fault current has not been interrupted following a set time delay from circuit breaker trip initiation, the CBF protection will operate, whereby the upstream circuit breakers are back-tripped to ensure that the fault is isolated.

Such faults may be due to a fault condition not having been removed from the feeder, or due to earthing clamps having been left on following maintenance.
