System description:
Introducing new epa 300, a portable standard meter
Used for the measurement of the three phase power
And the energy. Various measuring features combined with its easy operation concept provide the greatest possible flexibility for a comprehensive testing of metering installations on site.
Features:
1. On line calibration with external ct
2. Direct current option up to 10a
3. Accuracy < 0.2%
4. Large lcd display.
5. Pulse input & output
6. Sensor for pulse out led
Functions:
1. Power and energy measurement of active, reactive and apparent energy
2. Frequency-, phase angle- and power factor measurement.
3. Error measurement on electric meters.
Actual values measurement:
1. Rms values of all voltage and current phases
2. Currents for all 3 phases
3. Frequency and power factor - cos ϕ.
4. 3 phase - kw, kwh, kva, kvar, kvarh
5. Percentage of the measurement error with pulse input.
Technical data:
1. Power supply: 85-250vac, 50/60hz.
2. Voltage measurement: 0……300v
3. Voltage measurement accuracy: < 0.1%
4. Current measurement: 50ma ….10a (for direct measurement)1 a…1000a (for measurement with clip -on ct)
5. Current measurement accuracy: direct measurement <0.1% with external ct <0.2%.
6. Frequency measurement: 40….60hz.
7. Energy accuracy: <0.2%
