Page 61 MiCOM P225 Page 5/52 The MiCOM P225 relay can be withdrawn while it is live. This means that its live parts can be withdrawn from the metal housing while the relay is supplied with power via the auxiliary source. When the relay is drawn out of its housing:...
Page 62 THE OPERATOR INTERFACE Description of the front panel The front panel of the MiCOM P225 relay serves as an interface between the human and the protection relay. It enables the operator to enter settings, to gain access to the display of measured values and alarms, and also to display in a simple manner the different actions performed by the MiCOM P225 relay.
Page 63 (repair of the module, disappearance of the fault). LED 4 Colour: GREEN Wording: HEALTHY This LED indicates that the MiCOM P225 relay is energised within the rated range (0.8 to 1.2 Vaux). LEDs 5 to 8: Colour: RED These LEDs can be programmed by the operator in the CONFIGURATION menu.
Page 64 By default, a value is continuously displayed, and the operator can select this value from a list in the CONFIG. As soon as an alarm is generated by the MiCOM P225 relay, the relay indicates it by an alarm message: this display takes priority and replaces the default value (see the MOTOR ALARMS and HARDW ALARMS menus).
Page 65 All that is required then is to contact AREVA T&D or its agent, stating the serial number of the relay, to receive an emergency password specific to the relay concerned.

While the relay is in setting mode, the letter P (Parameter) is displayed at the bottom right of the menus and submenus headers.
Page 67 4.5.1.1 Setting group The MiCOM P225 relay has two configuration groups corresponding to two protection groups (menus PROTECTION G1 and PROTECTION G2). The operator can thus carry out 2 settings for each parameter: one for configuration group 1 and the other for configuration group 2.
Page 68 4.5.1.4 Analogue outputs (optional) The MiCOM P225 relay offers 2 optional analogue outputs to make the data available to a logic controller, at 0-20 mA or 4-20 mA as desired. The current loop support can be used as an active source circuit or a passive source circuit. The values which can be transmitted by these analogue outputs are: −...
Page 69 Four identical sub-menus - LED 5, LED 6, LED 7 and LED 8 are used to configure the 4 programmable LEDs of the MiCOM P225 relay. The user can assign one or several indications to each of these LEDs.

Page 75 The [49] THERMAL OVERLOAD submenu: Protection against thermal overload conditions The MiCOM P225 relay produces a thermal image of the motor from the line current and the negative component of the current consumed by the motor, in such a way as to take into account the thermal effects created in the stator and in the rotor.

Page 77 +40°C. The MiCOM P225 relay offers the possibility of taking into account this necessary derating of motors. The thermal image can be modified by the ambient temperature measurement.
Page 78 ALARM. Corrective action can thus be taken before thermal tripping occurs. Once the threshold θ ALARM is exceeded, the MiCOM P225 relay calculates and displays, in the PROCESS menu (cf. chapter 4.7 The PROCESS menu), an estimate of the time remaining before a thermal trip THERM.

Page 163 MiCOM P225 Page 3/18 INTRODUCTION The MiCOM P225 relays are fully numerical in design and employ a high degree of self- checking. Any fault affecting a hardware or software component is instantly detected and signalled as a device fault. BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE USER SHOULD BE FAMILIAR WITH THE CONTENTS OF THE "HANDLING AND...
Page 164 MiCOM P225 MAINTENANCE PERIOD It is recommended that products supplied by AREVA T&D receive regular monitoring after installation. As with all products some deterioration with time is inevitable. In view of the critical nature of protective relays and their infrequent operation, it is desirable to confirm that they are operating correctly at regular intervals.
Page 165 The logic inputs (opto-isolators) can be checked to ensure that the relay responds on energisation. This test checks that all 6 opto-isolated outputs of the MiCOM P225 are functioning correctly. Energise the logic inputs one at a time with voltage V, with the terminal numbers in accordance with the table below.
Page 166 P225/EN CM/B11 Maintenance Page 6/18 MiCOM P225 • While the MiCOM relay is in Maintenance mode: − All protective functions are disabled − All automation functions are disabled − All output relays are off (including the watchdog relay) − The ALARM LED flashes −...
Page 167 Before replacing the withdrawable part in the case, reset the 2 opposing cams. N. B.: MiCOM P225 relays have integral current transformer shorting switches which will close when the withdrawable part is removed. In case of fuse-contactor controlled by a voltage loss coil, do not remove the withdrawable part if the contactor is closed.
Page 168 P225/EN CM/B11 Maintenance Page 8/18 MiCOM P225 Exchanging the relay and the case BEFORE WORKING AT THE REAR OF THE RELAY, ISOLATE ALL VOLTAGE AND CURRENT SUPPLIES TO THE RELAY. DISCONNECT THE RELAY EARTH CONNECTION FROM THE REAR OF THE CASE.
Page 169 Page 9/18 CHANGING THE BATTERY MiCOM P225 relays have a battery to maintain status data and the correct time if the auxiliary supply voltage fails. The data maintained includes event, fault and disturbance records and the thermal state at the time of failure.
Page 170 P225/EN CM/B11 Maintenance Page 10/18 MiCOM P225 EQUIPMENT FAILURE: HARDWARE ALARMS Types of equipment failure As soon as an internal fault (i.e. an equipment failure) is detected in the MiCOM relay: • An alarm is displayed as a priority on the front panel display.

Page 255 As soon as they arrive, the relays should be examined immediately, looking for any deterioration which could have occurred during transport. If there is any deterioration, make a claim against the forwarding company and inform AREVA T&D as soon as possible.
Page 256 P225/EN IN/B11 Installation Guide Page 4/12 MiCOM P225 HANDLING ELECTRONIC EQUIPMENT The usual movements of a person easily generate electrostatic energy which may reach several thousand volts. The discharging of this voltage into devices comprising semiconductors, when handling electronic circuits, can cause severe deterioration. Such damage is not necessarily visible immediately.
Page 257 Installation Guide P225/EN IN/B11 MiCOM P225 Page 5/12 INSTALLING THE RELAYS The relays are supplied either individually or mounted in a cubicle. If separate relays have to be installed according to a particular drawing, please follow the mounting details indicated in publication R7012.
Page 258 P225/EN IN/B11 Installation Guide Page 6/12 MiCOM P225 UNPACKING When unpacking and installing relays, take great care to avoid damaging the parts and changing the settings. Relays must be handled only by people who are experts in this field. As far as possible, the installation must remain clean, dry, free from dust and free from excessive vibration.
Page 259 Installation Guide P225/EN IN/B11 MiCOM P225 Page 7/12 STORAGE If the relays do not have to be installed immediately on reception, they must be stored protected against dust and humidity in their original carton. If dehumidifying crystals are placed in the relay packaging, it is advisable not to remove them.
Page 260 The safety instructions described in this document are intended to guarantee correct installation and use of the MiCOM P225 relay and to avoid any damage. All persons directly or indirectly concerned with the use of these devices must be familiar with these safety instructions.
Page 261 Access to the connectors at the rear of the relays can present risks of electrocution and thermal shock. Before you consider energization, the MiCOM P225 relay must be connected to earth via the terminal provided for this purpose. Unless otherwise indicated in the technical data chapter of the product documentation, the minimum size recommended for the earth wire is 2.5 mm...
Page 262 P225/EN IN/B11 Installation Guide Page 10/12 MiCOM P225 7.6.2 Destruction It is recommended that the relay should not be incinerated nor thrown into a river. MiCOM relays and their components should be disposed of and recycled strictly in compliance with regulations on safety and the environment.
