The CL3013 is a reference standard with integrated three-phase current/voltage source.
It’s used for meter development, in laboratories, power companies or wherever you need a stabil current- and voltage output together with accurate measurements.
The accuracy of the reference standard is class 0.05.
Performed can be for example
- no load test
- starting test
- accuracy tests with current variation
- variation tests for voltage and frequency
- influence of harmonics tests
The functions can be controlled either by the integrated display or with our EMS5 software.
