High Precision AC and DC Sensors

Triskel’s precision power sensors are designed to monitor both DC and AC power flows around a vessel or house, providing a clear picture of total energy supply and consumption.

Each sensor measures current, voltage and temperature and reports this together with total power and amp hours. The sensors are non invasive, the power conductor passing through the sensor, and are fully isolated from the circuit being measured. This makes them ideal for measuring noisy electrical circuits subject to high current spikes such as propulsion systems with large inductive loads.

Data from the sensor is reported over the CAN bus making the sensor fully compatible with all other Triskel data management components. A simple graphical picture of the flows can be created allowing the user (or the control system) to make informed decisions about power use and cost.
