Description and usage

The alternative current board for Tyness Ewattch measures at high frequency, the currents on each of its 3 inputs. It enables to measure the current consumed by a device with great precision.

The data made available for each of the reading inputs are as follows:
– The total of the consumption of current in milliamps-hour
– The RMS current in milliamps

current and RMS current as a function of time

Two versions exist:

  • a version compatible with current transformers (TYNESS-OPT-CURR)
  • a version compatible with Rogowski loops (TYNESS-OPT-ROGOW)

References :

TYNESS-OPT-CURR are compatible with current transformers with the following references :

  • TYNESS-CUR-1 of diameter 10mm, 75A max, length 2 meters
  • TYNESS-CUR-2 of diameter 16mm, 100A max, length 2 meters
  • TYNESS-CUR-3 of diameter 24mm, 300A max, length 2 meters
  • TYNESS-CUR-4 of diameter 36mm, 600A max, length 2 meters

TYNESS-OPT-ROG are compatible with Rogowski loops with the following references :

  • TYNESS-ROG-1 of diameter 100mm, 3500A max, length 3 meters
  • TYNESS-ROG-2 of diameter 75mm, 3500A max, length 3 meters

The board TYNESS-OPT-ROG, in its standard version, is supplied with its Rogowski loops connected by welding to the board. However, it is available as an option with connectors.

The board is powered by the Tyness. The option of power supply with the external box TYNESS-OPT- PACK-PILE is not possible.
