2. Device Description
2.1 Introduction
The Reference Standard is the single-phase (RS 2110) and three-phase (RS 2310) version of
precision meter for electrical power and energy measurement.
The Reference Standard 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 real or artificial mode of operation in three phase system and is capable to evaluate the
individual quantities per phase and the three-phase cumulative quantities as well.
The Reference Standard is based on precision 24-bit A/D conversion and digital signal processing
technology enabling accurate evaluation of all main and informative quantities. Beyond measurement
of all kinds of power, voltage, current and phase, the meter measures the harmonic content and
distortion of the input signals.
The Reference Standard has independent input circuits for the individual phases. This feature in
combination with the possibility to assign the impulse output to any combination of the input channels
(phases) enables for example to use the device in one phase system while the free channels can gather
additional information like power consumption of the current and voltage circuits for contact error
monitoring.
The Reference Standard makes harmonic analyze of the voltage and current spectrum and
measures and computes these quantities shown in display of the device:
