Device Overview & Technical Specifications

- Powersense measures alternating current. The application displays four charts in total (3 phases + total consumption).
- This way of measuring can't be considered for the purpose of exact billing measurement because the approximate deviation is around 10-15%. It is not possible to achieve 100% accuracy. It measures trends in consumption rather than something which can be used for electricity billing.
- For this type of measurement, it is essential to know how many amps pass through the wires. Whether up to 80 Amps / up to 12 mm clips or clips up to 300 Amps / up to 36 mm, it is necessary to know the diameter of the cable (phase conductor) on which you will install the sensor. Therefore, the ideal solution before the purchase is to measure the diameter of the conductor – using callipers can provide an exact measurement.
