Description
The Reference Standard RS 2x30 is a single-phase (RS 2130) and three-phase (RS 2330) 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.
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 meter constant of Reference Standard generating value-proportional impulses on the four frequency outputs is freely programmable. This unique feature along with the extremely high maximum output frequency exceeding 2 MHz allows precision error evaluation of tested meters even at shortest integration period. All four freely programmable independent impulse outputs can be assigned to various quantities which for example enable to triple the testing capacity of the threephase test system when testing single-phase meters.
Any of impulse outputs can be set to generate any precise constant frequency for testing purposes.
The Reference Standard RS 2330 is equipped with three fully independent differential voltage input circuits. Therefore the meter can be configured to evaluate signals on three independent channels. This feature in combination with possibility to assign the impulse outputs to any combination of the input channels enables to use the device for example in single-phase system with one channel as reference while the free channels can monitor additional information like power consumption of the current and voltage circuits or contact error in the test circuit.
