Circuit-breakers for energy measurement and communication

A low voltage electrical installation is similar to an industrial process for electricity distribution

and needs a supervisory and monitoring system that is able to increase reliability and optimize

management.

To achieve integration between conventional plant engineering techniques and control sys-

tems for the purpose of running, controlling and monitoring civil and industrial installations in a

centralized and automatic way, one can consider the electrical installation as being affected by

two flows:

n a main flow (energy flow) formed by the power and energy supplied to the users and loads

of an installation through the line conductors and control and protection devices;

n an information flow (digital flow) formed by all the information, data and commands required

to control and manage the installation.

The supervisory system handles the flow of information that transits through the communica-

tion network.

Solutions for energy measurement and communication

In this type of installation, the circuit-breaker acts as both sensor and actuator. As a sensor,

it collects sensitive information and data and sends them to the supervision system. As an

actuator, it executes the command received from the control device (e.g. PC or PLC).

These characteristics are of particular importance since they meet the growing demands for

circuit-breaker integration into latest generation networks (Smart Grid).

XT4 250 Ekip E-LSIG 3p - Ekip Com, MOE-E

Due to its integrated current and voltage sensors, the Ekip E elec-

tronic trip unit can measure both the main electrical quantities and

the most advanced Power quality indicators; such as Power Factor,

Harmonic distortion and THD.

By means of the trip unit and Ekip Com Communication module,

the MOE-E motor operator allows the digital signals from the su-

pervision and control system to be used and converted into power

signals for operating the circuit-breaker in the remote mode.

T5 400 PR223DS 3p - MOE-E, VM210

Due the conventional L, S, I and G protection functions, the

PR223DS trip unit also allows the main electrical quantities to

be measured.

Using the VM210 accessory and without the need for voltage

transformers, the user can obtain both the current values and

the voltage, power and energy values in the local and remote

modes via a supervising and control system.

T7M 1600 PR332/P 3p - PR330/V, PR330/D-M

The SACE PR332 trip unit for Tmax T7 provides a sophisticated

and ﬂexible protection system. Fitted with the PR330/D-M internal

dialogue module, PR332/P becomes a smart protection, measur-

ing and communication device based on the Modbus

RTU

protocol. Module PR330/V measures and processes the neutral

and phase voltages, then transfers these data to the protection

release so that a set of protection and measuring functions can be

implemented.

HMI030

This device, which can be installed on the front of the switchboard,

comprises a graphic display showing all the measurements and

alarms/events of the trip unit. Thanks to its high-level accuracy, the

device is a valid substitute for conventional multimeters without the

need for current/voltage transformers.

XT2 160 Ekip LSIG 3p - Ekip Com, Ekip Display

Ekip Display is a unit that can be applied to the front of the ad-

vanced electronic trip unit and shows the current values, voltage

values, alarms and programmed protection and communication

parameter settings.
