The Enertex® KNX SmartMeter (4 TE DIN rail) is a bidirectional meter for measuring active and reactive energy or power, as well as for analysing network quality. The measurement is carried out either in a three-phase system or in three independent single-phase systems with accuracy class 1 (1%). In accuracy class 1 according to EN 62053-11, accuracy requirements are only specified for the measuring range between 2% and 100% of the nominal current. For smaller currents, no requirements are defined, as these cannot be accurately recorded with conventional current transformers. In contrast, the Enertex SmartMeter uses highly precise current sensors (Rogowski coils) that are calibrated to the device at the factory. This allows very small currents down to 0.002% of the nominal current (= 2 mA) to be measured precisely. In addition, the current measurement is particularly low-loss (< 2 mW loss). The supplied current sensors are suitable for through-hole mounting and may be installed directly at the network feed-in point.
The SmartMeter is powered exclusively via the bus. Therefore, the device can measure currents and voltages even if no 230 V mains voltage is present at the voltage measurement inputs or if the voltage has been switched off.
The measuring range of the active power extends from 0.5 W to 19,550 W or 58,650 W (three-phase). Energy values or measured variables for monitoring network quality are recorded in text form on an SD card for analysis. All measured values (current, voltage, active power, reactive power, active energy, reactive energy, power factor, THD-U, THD-I, network harmonics, load unbalance, neutral current, network frequency) are displayed on the KNX bus. All meter readings and measured variables are also recorded in text form with a timestamp on an SD card for further data processing.
In addition to specialised functions for load control dependent on power, optimisation of self-consumption with PV systems, calculation of usage or feed-in fees with tariff switching, and prevention of load peaks, the ETS application also provides various monitoring functions. These report events such as voltage outages, high voltage spikes, high network distortion, high reactive energy consumption, strongly uneven loading of the three phases (load unbalance), or high neutral conductor load on the bus when limit values are exceeded. For assessing network quality, harmonics up to the 50th order of current and voltage are measured. The numerous monitoring functions enable precise time analysis of network-related outages, faults, and damage to electrical equipment.
