The company's focus is in the field of test equipment designed for the purposes of testing electricity meters, current transformers and electrical network analysis.
TEST STATION
FOR 5, 10 OR 20 SINGLE OR THREE – PHASE ELECTRICITY METERS
Application and brief description
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:
- electronic phantom load
- energy standard
- mechanical construction for suspension
- error indicators
- scanning heads with mechanics for positioning
- computer and printer
Technical data
Three-Phase or Single-Phase Reference Standard
Accuracy class 0.05 or 0.1
Generates reference output frequency, proportional to the measured energy.
Electronic Three-Phase Phantom Load
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%
Universal Scanning Head EH 10
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
