The RD-30 three phase reference standard is one of the most versatile reference instruments ever. The RD-30 has a typical accuracy of ±0.02% @ PF=1 for all measurement functions across its entire operating range, with a maximum worst case accuracy of ±0.04%. This worst case accuracy specification includes the variables of stability, power factor, traceability uncertainty and test system errors.
A unique design makes the RD-30 unsurpassed in its ability to accurately measure “real world” waveforms. The RD-30 reference meter includes an exclusive analog to digital signal converter that is combined with Radian Research’s renowned electronically compensated voltage and current input transformers and a hermetically sealed reference. This combination provides the highest degree of accuracy, stability and versatility offered in a portable three-phase standard.
