Electronic power sources ZVE System, single up to three phase power sources The ZVE Power Source was specially designed for use as an electro technical current and voltage generator in Meter Test Systems and also in other automatic test systems. The power source creates the current and voltages - the phantom load - required for measuring the meters. The network as generated by the ZVE system is completely distinct from that of the mains power supply. The generated values are, consequently, practically independent of the quality of the public power supply. The ZVE system is composed, in general terms, of the following principal units: One up to three Voltage power sources PSU 10 One up to three Current power sources PSI 10 Control unit STE 10 Digital electronic reference meter SRS 121.3 or other types (Option) Voltage and current ranges: Voltage: 30 V up to 300 V Current: 1 mA up to 120 A or 1 mA up to 200 A Output power per phase: Voltage: 1000 VA / 2000 VA / 4000 VA Current: 1000 VA / 2000 VA / 4000 VA Power efficiency: > 85 % -3-
Reference Standards and Comparator Stationary Reference Standards The electronic system reference standards in 0.05 % or 0.02 % accuracy, are precision measurement units for all AC values, which are used in the measurement of energy. The wide measurement range and the high precision are the main characteristics of the reference standards. SRS 121.3, accuracy 0.05 % available in two versions: Current range: 1 mA ... 120 A or 1 mA ... 200 A SRS 400.3, accuracy 0.02 % Current range: 1 mA ... 120 A SRS 200.3, accuracy 0.02 % Current range: 1 mA ... 200 A PRS 400.3 Portable Reference Standard The PRS 400.3 reference standard of the modular system is based on the well-known digital measurement value retrieval, fast analogue-digital conversion and calculation of the values using fast signal processors. As opposed to the past, reference standards are not only used as standards for meter testing in a stationary meter test installation, but are also now predominantly used in the field for the measurement of all main parameters. K2006 Comparator The K2006 is a high accuracy comparator of accuracy class 0.01, especially suitable for use in metrological institutes and high precision measuring laboratories. Its ability to compare directly to an external DC reference allows easy traceability to national standards. Comparators are regularly used for checking of reference standard meters, for the calibration of precision current and voltage sources and for the verification of electrical standard measurements and electricity test systems. -4-
