TRIPHAS'O
Declaration of conformity
Presentation
The Triphas’O sensor is used to remotely read the electrical energy consumption of a three-phase installation in a non-intrusive way via the LoRaWAN™ network. It is specially designed to meet the energy management needs of industrial and tertiary buildings that operate with medium / high power, energy intensive equipment.

On/Off input
nput controlled:
- by a dry contact: pinching at the input ground, 10kΩ maximum contact resistance at ground.
- by 0 < VIL< 0.5VDCto deactivate the input and 2.5VDC< VIH< 30VDCto activate the input (10kΩ of serial protection beyond 5VDC).
The terminal marked on the housing corresponds to the ground on the board. Overvoltage protection.
Input connection to a dry contact:
The dry contact must take into account the low polarization current of the input. The use of a silver-or gold-plated contact is recommended to ensure the state is properly detected.
Input connection to a square signal:
Example using a polarized connector:
On/Off output
Electromechanical relay, 10kV insulation between the coil and the contacts.
Breaking capacity of 1A @ 230VRMS under purely resistive load.
Minimum current: 10mA @ 5VDC
Make contact, normally open.
Potential free, dry contact.
This output must be protected from overcurrents by an external device with a rating suited to the output capacity.
Function: status report (fault, deletion...)
Volatage Inputs
Each voltage input is equipped with a stage that allows the voltage to be reduced to a level compatible with the ADE9000 input stage.
Maximum voltage: 500VRMS
Measurement accuracy: 1%
Quantity: 4 (Neutral and 3 phases)
In the case of a star-type installation (4 wires), the neutral is present, hence the 4 points are used.
In the case of a delta-type installation (3 wires), there is no neutral, hence only 3 points are used.
In the case of a single-phase installation, only 2 points are used.
Current inputs
general
There are 3 current inputs.
In the case of a star-type installation, the 3 inputs are used.
In the case of a delta-type installation, the current in phase 2 is obtained by difference from the other 2. Only measurement points 1 and 3 are used.
polarity
In order to correctly measure the angle between voltage and current, the polarity must be observed when connecting current transformers. The 2 wires of the secondary circuit must be connected so as to be in the same direction as the primary current. In the event of an error, the phase measurement will be shifted by 180°.
The arrow indicates the direction of polarity to be observed, as per that on the primary of the current transformer.
0-60A range
Primary current transformation by a current transformer with a 1:3000 ratio @ 50 Hz (supplied)
Measurement accuracy: 3% of full scale (with a Class 2 current transformer)
0-400A range
Primary current transformation by a current transformer with a 1:5000 ratio @ 50Hz (supplied)
Measurement accuracy: 2% of full scale (with a Class 1 current transformer)
0-4000 A range
Transformation of the primary current by a Rogowski coil with a ratio of 22.5 mV/kA @ 50 Hz (not supplied)
Measurement accuracy: 1.5% of full scale (with a Class 0.5 Rogowski coil)
Radio propagation
Human Machine Interface
Radio Network
To start up the device, the radio button has to be pushed on the sensor for one second. After one second, the radio LED blinks slowly until the association is done.
To switch off the device, repeat the same operation by pressing the radio button for 5 seconds. After those 5 seconds, the radio LED blinks 5 times slowly.
- A reassociation procedure can be requested if no downlink frame is received by the sensor during a given periodicity (4 days by default) or if a given number (100 by default) is reached or in case of failure (no acknowledgement received) by sending an applicative frame to the sensor or via the sensor’s IHM.
The sensor keeps the AppEUi and DevAddr configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate …) are lost.
Feature is available by pushing 3 quick times on the radio button.
- A factory reset is available on nke Watteco’s sensors. It deletes all the applicative settings saved in the flash memory (i.e. configured batches and reports will be deleted).
The sensor keeps the AppEUi and DevAddr configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost.
Feature is available by pushing two quick times and a long time on the radio button.
Electrical Configuration
This keys and leds are used to configure the sensor in the appropriate type of installation.
- “4-wire” type installation, or
- “3-wire” type installation, or
- single-phase installation.
With each press, the sensor switches between the three modes. To tell the installer which mode the sensor is in, the latter will switch on:
- the "4-wire configuration" LED only (4-wire mode), or
- the "3-wire configuration" LED only (3-wire mode), or
- these 2 LEDs simultaneously (single-phase mode)
