Multisystem traction meter
About
The HEMR V1 multisystem traction meter measures the energy received and delivered in four quadrants with identification of active and reactive power. It is used to measure instantaneous electrical quantities such as voltage and current in AC and DC systems, with the identification of minimum and maximum quantities measured.
For its function it requires the installation of voltage and current measuring transformers or converters and is configurable for all levels of output voltages and currents used in traction systems.
It meets the requirements of EN 504 63:2017 standards for electricity meters of 0.5 R and 0.2 R accuracy classes, and the requirements of TSI LOC&PAS NK (EU) No 1302/2014.
Features
- Energy measurement in AC / DC grid systems
- Measurement of active and reactive energy, received and supplied in all quadrants
- Measurement of effective values of voltage, current and other quantities
- Load profile recording at minutes intervals
- 0.5 R and 0.2 R accuracy class under EN 50463:2017
- Possibility of calibration and sealing for billing purpose
- Integrated RS/485 interface with IEC62056 protocol
- Operating temperature range from -40°C to +70°C
- Rated supply voltage 24VDC - 110VDC
