Applications

Basic Metering

The RTM 050 provides full scale ±0.5% high accuracy measurements for power system parameters[voltages, currents, power, energy, frequency and power factor] in power system. Recently most of power system environments comprise industrial loads with non-linearity generating many harmonics. However, the device guarantees high accuracy measurements in the power system distorted with harmonics

Online Monitoring/Control

The RTM 010 has a RS485 port and supports Modbus RTU protocol. Users easily build online power monitoring system by PowerDX software or any other automation programs. Particularly the digital inputs and outputs of the device make it possible for users to recognize the information of the digital contacts and control the digital output hannels on communication.

Power Management

The electrical energy data from the meters offers users the information for management and analysis of energy usage, adapted to operate or plan the power facilities of energy suppliers and consumers recently or in the near future.
