Reference standard RS

The Reference Standard RS is precision standard meter in single- and three-phase version for electrical power and energy measurement. It is designed to meet all requirements put on a reference standard in a single- and three-phase electricity meter testing and calibration systems. The Reference Standard can be set to any true or artificial mode of operation in three phase system and is capable to evaluate individual quantities in any phase and three-phase cumulative quantities as well.
