The meter test station allows simultaneous testing of 3, 5, 10 or 20 induction or static electricity meters. The test station could be constructed for single-phase electricity meters or for three-phase meters.
Each station consists of the following elements:
Accuracy class 0.05 or 0.1
Generates reference output frequency, proportional to the measured energy.
The values of the output signals are digitally synthesized, not depending on the network stability.
Output power 150/300/600 VA (depending on the number of the electricity meters)
Voltage ranges 30 V÷ 300 V (controllable at an interval of 0.1 V)
Current ranges 0.001 ÷ 100A (controllable at an interval of 0.01 A)
Phase angle 0° ÷ 360° (resolution 0.1°)
Non-linear distortion 〈 1%
Stability ± 0.1%
Reads the signal from a rotating disc or from an impulse light-emitting diode (liquid crystal)
Impulse output of the “Open Collector” type
Position indicator light
Two impulse inputs
Digital error indication in %
Computer interface RS485
Meter suspension rack
Mechanisms for fixing and positioning of the scanning heads
Automatic or manual connection of the current and voltage cables
“Meter Calibration” Mode
Generation of test reports
Storing of the measurement results.
