| Öğe açıklaması | Energy flow relay / relays for energy flow EFR4002IP monitor the current flow between the public power grid and the generating plant / consumer. The operation is made comfortably via an integrated webserver or directly at the device. The measured values are displayed on the device or on a monitor. The device meets the requirements of pav, e monitoring according to VDE-ar-n 4105 (compliance monitoring of the agreed active power connected to the public grid). In addition to the relay function, the EFR4002IP CAN also be used as a sensor for energy flow direction (ENFLURI) or as a measuring instrument for monitoring the power quality. In addition to current, voltage, frequency, energy and active power, the device also measures the apparent and the reactive power, the power factor and the phase angles (UX^2UY and ix-iy). All these physical quantities CAN be read via MODBUS TCP |
