Energy Management

Smart System communications mean visible information.

Grouping most of the electrical protection, command and metering components, the switchboards are now significant sources of data locally displayed and sent via communication networks.

Smart Systems use reliable, simple-to-install-and-use displays, and Ethernet and Modbus interfaces.

Information is safely transmitted through the most efficient networks:

• Modbus SL inside switchboards, between components

• Ethernet, on cable or WiFi, inside the building and connecting switchboards and computers

• Ethernet or GPRS, for access to on-line services by Schneider Electric

• Energy experts, no matter where they are located, can now provide advice based on the updated data of the building.

On-Site Real-Time Monitoring

The FDM128 touch screen display connected to the Ethernet:

• shows essential electrical information and alarms concerning the electrical network

• allows control (open, close, reset) of various equipment

The FDM128 touch screen provides real-time value checking and control, directly on the front panel of the main switchboard. On a PC display with common browser:

• shows monitoring web pages hosted into the local Ethernet interface

• alarm events generate automatic email notifications

• allows control (open, close, reset) of various equipment

The data is displayed graphically or recorded into files for optimizing the use of energy in the building. As an example, the data can help validate the change of temperature settings, time scheduling in a Building Management System or other automated devices.

On-Line Energy Management Services

StruXureWare Energy Operation automates data collection using an open, scalable, and secure energy management information system.

With the help of the Schneider Electric energy management services team, data is turned into information to enable customers to understand their facilities’ performance on an ongoing basis.

Energy Operation leverages companies’ current investments in their existing systems, and can be used to communicate advanced results and performance to a broad audience for a shared understanding throughout an organization.

Trip Unit LCD

The user can display all the protection settings and the main measurements on the LCD screen of the trip unit.

• MicroLogic A trip unit: instantaneous rms current measurements

• MicroLogic E trip unit: voltage, frequency and power measurements and energy metering, in addition to the measurements offered by MicroLogic A

To make the display available under all conditions and increase operating comfort, an external power supply is recommended for MicroLogic A trip unit. It is required to:

• display faults and interrupted current measurements

• use all the functions of MicroLogic E trip unit (such as metering of low power and energy values)

• ensure operation of the communication network

The external power supply can be shared by several devices. For description, see 24 Vdc Power Supply.

Display Function

The FDM121 switchboard display unit can be connected to a communication (COM) option (Breaker Communication Module [BSCM]) using a circuit breaker ULP cord to display all measurements on a screen. The LCD screen is 3.78 x 3.78 in. (96 x 96 mm). The FMD121 display unit requires a 24 Vdc power supply. The COM option (BSCM) unit is supplied by the same power supply via the circuit breaker ULP cord connecting it to the FDM121. See FDM121 Display for more information.

For all FDM, in addition to the information displayed on the MicroLogic trip unit LCD, the FDM screen shows demand, power quality, and maximum/minimum ammeter values along with histories and maintenance indicators.

Measurement Function

The MicroLogic trip unit continuously displays the RMS value of the highest current of the three phases and neutral (Imax). The navigation buttons can be used to scroll through the main measurements.

In the event of a fault trip, the trip cause is displayed.

The MicroLogic A trip unit measures phase, neutral, and ground fault currents.

MicroLogic E trip units offer voltage, power, frequency, and energy metering in addition to the measurements provided by MicroLogic A trip units.

Every instantaneous measurement provided by MicroLogic A/E trip units can be associated with a maximum/minimum ammeter. The maximum for the highest current of the three phases, neutral, and demand current can be reset using the MicroLogic trip unit keypad, FDM display unit, or the communication system.

The MicroLogic E trip units also measures the energy consumed since the last reset of the meter. The active energy meter can be reset using the MicroLogic trip unit keypad, the FDM display unit, or the communication system.

MicroLogic E trip units also calculate demand current and power values. These calculations can be made using a block or sliding interval that can be set from five to sixty minutes in steps of one minute. The window can be synchronised with a signal sent through the communication system. Whatever the calculation method, the calculated values can be recovered on a PC through the communication network.

Ordinary spreadsheet software can be used to provide trend curves and forecasts based on this data. They provide a basis for load shedding and reconnection operations used to adjust consumption to the subscribed power.

The MicroLogic E trip unit calculates power quality indicators taking into account the presence of harmonics up to the fifteenth harmonic, including the total harmonic distortion (THD) of current and voltage.

The FDM121 is intended to display MicroLogic trip unit measurements, alarms and operating information. It cannot be used to modify the protection settings.

Measurements can be easily accessed using a menu. All user-defined alarms are automatically displayed. The display mode depends on the priority level selected during alarm set-up:

• high priority: a pop-up window displays the time-stamped description of the alarm and the orange Alarm LED flashes;

• medium priority: the orange Alarm LED goes continuously on;

• low priority: no display on the screen.

All detected faults resulting in a trip automatically produce a high-priority alarm, without any special settings required. In all cases, the alarm history is updated. The MicroLogic trip unit saves the information in its non-volatile memory in the event of an FDM121 power loss.

FDM121 Display

Surface Mount Accessory

When the circuit breaker is equipped with the Breaker Communications Module (BSCM), the FDM121 display can also be used to view circuit breaker status conditions:

• O/F: ON/OFF

• SD: trip indication

• SDE: fault-trip indication (overload, short-circuit, or ground fault).

When the circuit breaker system is equipped with the I/O application module, the FDM121 can monitor and control:

• cradle management

• circuit breaker operation

• light and load control

• custom applications.

When the circuit breaker is equipped with the communication motor operator etc., the FDM121 display can also be used to control (open/close) the circuit breaker.

Two operating mode are available:

• local mode: open/close commands are enabled from the FDM121 while disabled from the communication network;

• remote mode: open/close commands are disabled from the FDM121 while enabled from the communication network.
