WATTECO TRIPHAS’O LoRaWAN Remote Reading Sensor Instructions

WATTECO TRIPHAS’O LoRaWAN Remote Reading Sensor Instructions

The TRIPHAS’O sensor allows the remote reading of the electrical energy consumption of a three-phase installation in a non-intrusive way via the LoRaWAN® network. In a single-phase installation, it is used for submetering. The sensor is specially designed to meet the energy management needs of industrial and tertiary buildings, operating with medium and high energy consumption equipment.

APPLICATIONS

• Telemetry, energy management
• Real-time monitoring of power consumption at the three-phase meter
• Submetering on up to 3 single-phase circuits
• Any industrial application: industry, shopping centres, data centres…

BENEFITS & KEY FEATURES

• LoRaWAN®, Class C
• Easy to use and deploy
• External RF antenna which can be remote
• Measurements at regular intervals
  • Active, reactive power
  • Active, reactive energy
  • Average or instantaneous power (analysis of change of consumption/maintenance regime).
  • RMS voltages and currents

QUALITY & RELIABILITY

RED, RoHS

Two versions of the TRIPHAS’O sensor are available in order to meet electrical measurement requirements:

• with current transformers (opening – nonintrusive) for low power,  primary reference current: 0-60A or 0-400A.
• with Rogowski loops (opening – non-intrusive) for high power, primary reference current from 0 to 4000A

On a three-phase meter, the TRIPHAS’O sensor provides for each phase, the active and reactive energy indexes, the different powers available, the RMS voltages, the RMS currents and the current/voltage phase shift angles. It transmits the sum of the different energy indexes and differentpowers of the three phases L1, L2, L3.

On a single-phase installation, the TRIPHAS’O sensor provides the energy and power absorbed on each circuit (submetering).

The energy and power transfer is carried out at 10-minute intervals by default. The aim is to recreate the load curve.
The interval can be reconfigured via the LoRaWAN® downlink; it is possible to go down to 30s to have a transient analysis during maintenance periods for example.

The implementation of the sensor is quick and simple: the sensor is fixed on a DIN rail next to the electrical circuits. The external antenna can be mounted on a cable (not supplied) when the sensor is installed in a metal cabinet. A remote waterproof antenna kit is available as an option.

The sensor is powered from the mains 50Hz – 60Hz with 230 Volts between phase and neutral (or 400 Volts between two phases). The sensor is built as a Class II construction.

The connections are made via spring-loaded terminal blocks.
