11/664

Pxxx/EN SS/G11


To ensure that wires are correctly terminated the correct crimp terminal and toolfor the wire size should be used.

The equipment must be connected in accordance with the appropriate connectiondiagram.

Protection Class I Equipment

- Before energizing the equipment it must be earthed using the protectiveconductor terminal, if provided, or the appropriate termination of thesupply plug in the case of plug connected equipment.

- The protective conductor (earth) connection must not be removed sincethe protection against electric shock provided by the equipment would belost.

- When the protective (earth) conductor terminal (PCT) is also used toterminate cable screens, etc., it is essential that the integrity of theprotective (earth) conductor is checked after the addition or removal ofsuch functional earth connections. For M4 stud PCTs the integrity of theprotective (earth) connections should be ensured by use of a locknut or

similar.The recommended minimum protective conductor (earth) wire size is 2.5 mm(3.3 mm for North America) unless otherwise stated in the technical data sectionof the equipment documentation, or otherwise required by local or country wiringregulations.

The protective conductor (earth) connection must be low-inductance and as shortas possible.

All connections to the equipment must have a defined potential. Connections thatare pre-wired, but not used, should preferably be grounded when binary inputsand output relays are isolated. When binary inputs and output relays areconnected to common potential, the pre-wired but unused connections should beconnected to the common potential of the grouped connections.

Before energizing the equipment, the following should be checked:

- Voltage rating/polarity (rating label/equipment documentation),

- CT circuit rating (rating label) and integrity of connections,

- Protective fuse rating,

- Integrity of the protective conductor (earth) connection (whereapplicable),

- Voltage and current rating of external wiring, applicable to the application.

Accidental touching of exposed terminals

If working in an area of restricted space, such as a cubicle, where there is a risk ofelectric shock due to accidental touching of terminals which do not comply withIP20 rating, then a suitable protective barrier should be provided.

Equipment use

If the equipment is used in a manner not specified by the manufacturer, theprotection provided by the equipment may be impaired.

Removal of the equipment front panel/cover

Removal of the equipment front panel/cover may expose hazardous live parts,which must not be touched until the electrical power is removed.


12/664

Pxxx/EN SS/G11


UL and CSA/CUL Listed or Recognized equipment

To maintain UL and CSA/CUL Listing/Recognized status for North America theequipment should be installed using UL or CSA Listed or Recognized parts forthe following items: connection cables, protective fuses/fuseholders or circuitbreakers, insulation crimp terminals and replacement internal battery, as

specified in the equipment documentation.For external protective fuses a UL or CSA Listed fuse shall be used. The Listedtype shall be a Class J time delay fuse, with a maximum current rating of 15 Aand a minimum d.c. rating of 250 Vd.c., for example type AJT15.

Where UL or CSA Listing of the equipment is not required, a high rupturecapacity (HRC) fuse type with a maximum current rating of 16 Amps and aminimum d.c. rating of 250 Vd.c. may be used, for example Red Spot type NIT orTIA.

Equipment operating conditions

The equipment should be operated within the specified electrical andenvironmental limits.

Current transformer circuits

Do not open the secondary circuit of a live CT since the high voltage producedmay be lethal to personnel and could damage insulation. Generally, for safety,the secondary of the line CT must be shorted before opening any connections toit.

For most equipment with ring-terminal connections, the threaded terminal blockfor current transformer termination has automatic CT shorting on removal of themodule. Therefore external shorting of the CTs may not be required, theequipment documentation should be checked to see if this applies.

For equipment with pin-terminal connections, the threaded terminal block forcurrent transformer termination does NOT have automatic CT shorting on removal

of the module.

External resistors, including voltage dependent resistors (VDRs)

Where external resistors, including voltage dependent resistors (VDRs), are fittedto the equipment, these may present a risk of electric shock or burns, if touched.

Battery replacement

Where internal batteries are fitted they should be replaced with the recommendedtype and be installed with the correct polarity to avoid possible damage to theequipment, buildings and persons.

Insulation and dielectric strength testing

Insulation testing may leave capacitors charged up to a hazardous voltage. At the

end of each part of the test, the voltage should be gradually reduced to zero, todischarge capacitors, before the test leads are disconnected.

Insertion of modules and pcb cards

Modules and PCB cards must not be inserted into or withdrawn from theequipment whilst it is energized, since this may result in damage.

Insertion and withdrawal of extender cards

Extender cards are available for some equipment. If an extender card is used,this should not be inserted or withdrawn from the equipment whilst it is energized.This is to avoid possible shock or damage hazards. Hazardous live voltages maybe accessible on the extender card.


13/664

Pxxx/EN SS/G11


External test blocks and test plugs

Great care should be taken when using external test blocks and test plugs suchas the MMLG, MMLB and MiCOM P990 types, hazardous voltages may beaccessible when using these. *CT shorting links must be in place before theinsertion or removal of MMLB test plugs, to avoid potentially lethal voltages.

*Note: When a MiCOM P992 Test Plug is inserted into the MiCOM P991 TestBlock, the secondaries of the line CTs are automatically shorted, makingthem safe.

Fiber optic communication

Where fiber optic communication devices are fitted, these should not be vieweddirectly. Optical power meters should be used to determine the operation orsignal level of the device.

Cleaning

The equipment may be cleaned using a lint free cloth dampened with clean water,when no connections are energized. Contact fingers of test plugs are normallyprotected by petroleum jelly, which should not be removed.

5. DECOMMISSIONING AND DISPOSAL

De-commissioning

The supply input (auxiliary) for the equipment may include capacitors across thesupply or to earth. To avoid electric shock or energy hazards, after completelyisolating the supplies to the equipment (both poles of any dc supply), thecapacitors should be safely discharged via the external terminals prior tode-commissioning.

Disposal

It is recommended that incineration and disposal to water courses is avoided.The equipment should be disposed of in a safe manner. Any equipmentcontaining batteries should have them removed before disposal, takingprecautions to avoid short circuits. Particular regulations within the country ofoperation, may apply to the disposal of the equipment.

3. PRODUCT SCOPE

MiCOM P441, P442 and P444 Numerical Full Scheme Distance Relays providecomprehensive distance protection for different applications like: lines, cables, tapped lines,lines with multiple zero sequence sources, non-homogeneous lines, series compensatedlines and parallel lines.

The independently settable resistive reach for each zone allows easy application to shortlines and cable protection. Using well-proven, patented techniques to directionalise, andmaking full use of digital memory, the relays can be applied in situations that can causeclassic distance implementations to maloperate (crosscountry faults, close-up faults, etc.).

The MiCOM P441, P442 and P444 are in-built with a library of channel aided scheme logic,supplementary and back-up protection. It provides complete protection (4 alternative settinggroups) to solidly earthed systems from distribution to transmission voltage levels.

Three phase tripping with faulted phase indication is provided for all protection functions. Inaddition models P442 and P444 allow single-phase tripping for the distance protection andthe channel aided DEF protection (67N).

The P441, P442 and P444 distance relays equipped with 150MHz CPU and coprocessorboard have been enhanced as described in the following table:

The fixed function LEDs on the left hand side of the front panel are used to indicate thefollowing conditions:

Trip (Red) indicates that the relay has issued a trip signal. It is reset when theassociated fault record is cleared from the front display. (Alternatively the trip LED canbe configured to be self-resetting)*.

Alarm (Yellow) flashes to indicate that the relay has registered an alarm. This may betriggered by a fault, event or maintenance record. The LED will flash until the alarmshave been accepted (read), after which the LED will change to constant illumination,and will extinguish when the alarms have been cleared.

Out of service (Yellow) indicates that the relays protection is unavailable.

Healthy (Green) indicates that the relay is in correct working order, and should be onat all times. It will be extinguished if the relays self-test facilities indicate that there isan error in the relays hardware or software. The state of the healthy LED is reflectedby the watchdog contact at the back of the relay.

To improve the visibility of the settings via the front panel, the LCD contrast can be adjusted

using the LCD Contrast setting with the last cell in the CONFIGURATION column.1.2.2 Relay rear panel

The rear panel of the relay is shown in Figure 3 (refer to section P44x/EN IN Installation forterminals connections layout). All current and voltage signals, digital logic input signals andoutput contacts are connected at the rear of the relay. Also connected at the rear is thetwisted pair wiring for the rear EIA(RS)485 communication port, the IRIG-B timesynchronising input and the optical fibre rear communication port which are both optional. Asecond rear port (Courier) and an interMiCOM port are also available.
