MiCOM I400

Digital Transducers

IntroductionThe MiCOM I400 range of digitaltransducers is designed to meet theworld market requirements of highaccuracy with optional digitalcommunications at a competitiveprice.

Available in two compact casesizes of 45mm and 100mm wide,these transducers can be suppliedfully calibrated or as a device for

customer calibration.

A multifunction transducer isavailable offering measurement of all power system parameters in onehousing with up to three optionalanalogue outputs.

Product features

• Full range of ac and dc measurements

• Programmable versions

• Multifunction transducer available to measurecurrent, Volts, frequency, phase angle, powerfactor, Watts, vars, VA, demands and harmonics.

• Up to three isolated analogue outputs

• Optional high speed RS485 or RS232communications

• Optional universal AC/DC power supply

• High sample rate (64 samples per cycle) foraccurate measurement of harmonics

• Two times continuous current overload rating0.5% full scale accuracy for all transducers

• Compact case design for DIN rail mounting

• Stripped wire terminations

• Tested to DIN 57875 level N for radio frequency

and electromagnetic interference immunity

Customer benefits

• All requirements can be sourced from one supplier

• Configurable on-site using a laptop PC. Simplifiedordering and easy to change configuration if site isexpanded or changed

• Reduced costs for sites requiring multiplemeasurements

• Analogue schemes require fewer transducersresulting in lower costs

• Can be integrated into modern control schemesutilising digital communication technologies

• Provides flexibility in terms of power requirementsand reduced stocking

• Gives accurate measurements of parameters criticalfor optimum plant use

• Lifetime durability and reliability

• Occupies minimal panel space

Applications

Applications are found in electricalutilities, switchgear/switchboardmanufacturers, energymanagement, SCADA, buildingmanagement and control, processcontrol and instrumentation.

MiCOM I400 digital transducersprovide local and remote indicationfor precision electrical measurementand control when used withinstruments, recorders, data loggersand SCADA systems (SupervisoryControl and Data Acquisition).

Provision of both analogue outputsand RS485/RS232 MODBUScommunications facilitatesintegration within existing sites and

new facilities where digitalcommunications are used.

The ease of programmability of digital transducers is an importantfeature in the provision of costeffective system control. Systemscan be easily changed orexpanded as required. Scalingdetails may be delayed while thesystem is being constructed withoutcausing costly project time delays.

Why MiCOM I400 digitaltransducers?

As well as allowing integration intodigital control schemes, MiCOMI400 digital transducers use stateof the art microprocessortechnology to enable customerconfiguration using only a personalcomputer and configurationsoftware.

Stability

The use of microprocessortechnology in the design of theMiCOM I400 digital transducerrange guarantees accuracy andstability over a range of temperatures. The good long termstability achieved reduces theproblem of long term drift that canaffect some analogue transducers.This level of stability means thatMiCOM I400 digital transducers

can endure a lifetime of maintenance-free operation.

Inherent design quality

ALSTOM T&D LtdProtection & Control operatesmanufacturing and quality systemsthat meet and exceed therequirements of ISO 9001.

Multifunction programmable

Each device measures volts,current, frequency Watts, vars, VA,phase angle, power factor, THD%,dynamic demands, maximumdemands and optionally, harmonicanalysis.

All measurements are available viathe communications port.

The multifunction transducer isalways supplied with the universalac/dc power supply andcommunications port for customerconfiguration.

The multi-function transducer isavailable with none, one, two orthree analogue outputs. Eachoutput can be programmed to anyof the following measured functions: -

• RMS current:Phase Ia, Ib, Ic,I average, In

• RMS voltage:Line to neutral: Va, Vb, Vc,

Configuration

Transducers supplied without thecommunications interface aresupplied factory pre-configured forwhich the scaling details must besupplied with the order.

Transducers with thecommunications interface can beordered as factory pre-configuredor as a programmable version forcustomer configuration. Freesoftware to allow customerconfiguration from a PC isavailable at the time of order

The programmable devices aresupplied with one of three outputranges. Each can be programmedfor a unidirectional, a bidirectionalor a bent characteristic.

The three output types can beprogrammed over the ranges asbelow : -

Output reference Type P : -

1…0…1 mA to 5…0…5 mA

Output reference Type Q : -

6…0…6 mA to 20…0…20 mA

Output reference Type R : -

1…0…1 V to 10…0…10 V

Other connections

Notes: I400 Communications port connections

RS232 Rx = terminal 21Com = terminal 22Tx = terminal 23

RS485 RxTxA = terminal 21No connection = terminal 22RxTxB = terminal 23

An auxiliary power supply is necessary for all the transducers except for the self powered current andvoltage transducers.

Output designations for multiple output transducers

Note: By default single output transducers always utilise the above terminal designations for output 1.

Caution! Refer to Operating &Maintenance manual beforeinstalling, commissioning, or

operating the equipment

1. Installation, commissioning andmaintenance should only becarried out be suitably qualifiedpersonnel.

2. Terminations exposed duringinstallation, commissioning andmaintenance may present ahazard unless the equipment iselectrically isolated.

3. The equipment should only beoperated as intended eg. withthe covers in place, and withinthe specified electrical andenvironmental limits.

4. Due to the presence of electrostatic sensitive devices onthe printed circuit board,appropriate ESD protection mustbe taken before commencinginstallation, commissioning ormaintenance.
