The optical probe CL4S is used for local communication with electrical energy meters. It’s compliant with the IEC 62056-21 . The communication is galvanically isolated.
Single phase meters with closed I-P links require galvanic isolation for testing. This galvanic isolation is done by a Multi Secondary Voltage Transformer (MSVT).
Our three phase test bench for type tests and for calibration of electrical energy meters.
The CL3013 is a reference standard with integrated three-phase current/voltage source. It’s used in laboratories of power companies or metrological institutes.
We offer a wide range of stationary test equipment for electrical energy meters. All test results are traceable to international standards.
The CLOU EMS5 software is a controlling software for stationary and portable meter test equipment.
If a meter has no possibility to open the internal link between voltage and current, the test must be performed with an Isolated Current Transformer (ICT) at each measurement position.
The reference standard is used in energy meter test benches for high precision measurements of voltage, current, phase-shift and frequency. The accuracy class is 0.02.
The portable reference standard and calibrator RS350 is especially designed for the needs of metering engineers for on-site testing with high precision.
