Three-phase, fully automatic test system with class 0.05 refer­ence standard and integrated three-phase current and voltage source. The PTS 3.3 C allows the monitoring of meter installations as well as analysis of the local mains conditions.

Advantages
·Easy verification of meters under precise load conditions, using the built-in, compact, current and voltage source.
·Automatic operation with predefined load points without the need for an external PC.
·Exchangeable Compact Flash (CF) memory card for measure­ment results and customer data.
·The system may be used either as a stand-alone reference standard meter, or together with the integrated power source.

Functions
·Independent generation of single or three-phase loading con­ditions for verification of meters.
·Active, reactive and apparent energy measurement for three phase, 3 or 4-wire, systems with integrated error calculator and pulse output.
·Burden measurement of Current Transformer (CT) and Poten­tial Transformer (PT).
