Solution for Power Quality and Energy Consumption Monitoring

Nowadays, power quality issues are more and more frequent due to disturbances such as harmonics, flicker, swells/sags, interruptions, unbalanced voltage, etc. This paper presents a solution developed by the authors for the monitoring of electrical energy consumption and power quality in one USV (University "Stefan cel Mare", Suceava) laboratory using two Janitza measurement devices (UMG507E and UMG96S). The UMG 507E device has the gateway integrated and can be used as a Modbus RTU master and UMG 96S is Modbus RTU (slave) in Modbus network. The data from both measuring devices is collected through Modbus master using ScadaBR software.
