MiCOM P111Enh

Numerical three phase and earth fault overcurrent relays

MiCOM P111Enh

Documents

• Catalogue card

• User manual

MiCOM P111Enh relays provide features for easy adaptation to different applications and operation conditions.

The P111Enh can be fully configured manually, without using setting software.

Alternatively, MiCOM S1 Studio setting software allows configuration parameters to be modified for a specific application via the USB port.

IEC 60870-5-103 and Modbus RTU integrated communication protocols are available for flexible integration into most substation control or DCS systems.

Close and Trip commands can be executed via functional key on the front panel, default menu window, DCS/SCADA system (RS485) or configured binary input.

Three level password gives proper rights for secure maintenance of the relay.

As a device housed in a small sized flush-mountable case, the P111Enh can be easily installed in all modern, dimension-focused switchgear panels.

The relay can be also considered as a costeffective answer to retrofit demands of older substations.

Selectable measuring criteria: True RMS and/or fundamental frequency (Fourier) current measurements allow to increase selectivity and adapt to the application.

Application

The MiCOM P111Enh (Enhancement) relays are suitable for all the application where overcurrent and/or earth-fault protection are required.

P111Enh can be applied to medium and low voltage electrical systems as an optimized and cost efficient solution tailored to user’s needs.

The MiCOM P111Enh numerical overcurrent protection relays provide an optimized and cost efficient solution.

Typical applications are:

• Utility and industrial substation fitted with costoptimized MV switchboards

• Retrofit relays of old technology, particularly during installation of DCS systems

• Transformers, incomers, bus couplers, capacitor banks, overhead lines and underground cables on MV systems

• Neutral system protection (insulated, solid and resistance earthed)

• LV substations

Main features

The following functions are generally available in all devices (refer to Table 1 below):

• Operate in 1, 2, or 3-phase arrangement.

• Two setting groups, selected from the relay menu, binary input or SCADA/DCS.

• Flush mounted case.

• Fundamental (fn) and True RMS (within a frequency range from 10Hz to 1kHz) phase current value measurement.

• Earth current fundamental (fn) frequency measurement.

• 9 button keypad to input settings, configure the relay and close and trip command and display

(2x16 LCD).

• Fault record for most recent trips.

MV Changeover Automation


MV CHANGEOVER DEVICES

Hardware

• Changeover scheme utilises programmable logic of MiCOM P132 (or MiCOM P139) relay. For the relays description see page 12 and 13 of this

Guide.

Principles of Operation

Two scheme configurations are possible:

• Information on primary voltage interruption is sent from voltage relays (e.g. MiCOM P921) located in measuring bays to binary inputs of a P13x relay, which initiates the course of the changeover scheme. During the course of the scheme the P13x performs several control operations (opening and closing CBs), using its auxiliary output relays and binary inputs. A manner to initiate the scheme can be selected by a user out of the following options:

• on energising of a binary input of the device, assigned to an output relay of undervoltage facility in the measuring bay

• on tripping of a protection relay in a transformer bay, having confirmed a change of CB state in the primary supply bay

• remotely, on sending a system command.

On the basis of the state of a bus coupler CB, the P13x selects a type of back-up supply configuration. Accordingly, a changeover scheme mode and a sequence of control operations are chosen automatically. The device may be programmed to operate both in 1-shot changeover scheme and in return changeover scheme.

The scheme can be blocked by:

• external signals, sent to binary inputs from other controllers or functional relays, located in other bays

• internal signals, sent from an integrated facility which monitors the switching state, or after a successfully completed scheme

• a system of higher level.

• If no protection relay is required in a bus coupler bay, the P13x utilises its binary inputs and output relays only, whereas its protection facilities are disabled.

• There are 2 MiCOM P13x devices installed in parallel in 2 feeder bays. In such a case the relays perform several protection functions for feeder lines, apart from the changeover scheme features described above.
