The SenNet Meter is a submetering counter with a minimum accuracy of ± 1% and the following features:
- Capable of taking both three-phase readings and readings from 3 single-phase circuits
- Available for both /5A and 0.33 V type current transformers (see the advantages)
- Incorporates display and keypad
- The RS485 interface with Modbus RTU protocol means the data captured for voltages, currents, powers, energies, cosine phi, frequencies, harmonics up to 15º, etc., can all be read
SenNet Meter Modular
The SenNet Meter Modular equipment affords modular metering of up to 20 three-phase or 60 single-phase circuits. Minimum accuracy of ± 1%.
The equipment includes:
- Header with a master and communications module. Includes display and keypad.
- Up to 10 modules, each of which can measure 2 three-phase, 6 single-phase or 1 three-phase + 3 single-phase circuits.
The unit’s main features are:
- Very compact, even with its maximum configuration of 20 meters it is still only 40 cm wide
- Very simple to install thanks to a single voltage input, a feature shared by all of the meters, and the removable connectors for the voltage transformers
- Configured for 0.33 V type voltage transformers
EMN-RF is a 20 – 2,000 A wireless meter that connects with the SenNet DL160 and SenNet DL161 dataloggers using the dataloggers’ integrated radio frequency network; as such, apart from serving as a meter, it extends the radio network.
Up to 200 A uses split-core sensors and from 200 A upwards Rogowski type sensors are used.
Advantages of 0.33 V current transformers
The 0.33 V current transformers facilitate current measurement in electrical circuits with significant advantages:
- Open-core type, easily mounted and a high accuracy of ± 1%.
- The circuits can be summed without needing to use matching transformers
- The separation distance between themselves and the meters can extend up to 100 m or more.
