Meter test systems with high accuracies of up to 0.05% and a wide measuring range for precise measurements in single- and three-phase applications. The meter test systems of the METES series are used to test the accuracy of Ferraris meters and electronic electricity meters under any operating conditions. The impact of system perturbations such as harmonics or flicker on the meter can be taken into consideration during tests.
Three Phase Measurement Test System
A field instrument specifically designed to cover all aspects of metering installation, commissioning and maintenance activities. Including the calibration of single and three phase energy meters, and meter installation audits. The device features powerful on-board data storage. It uses easy menu driven function / option selection. It also implements the KoCoS SmartProbe technology.
Energy Meter Calibration
The unit is capable of calibrating the energy and maximum demand (kVA & kW) functions of energy meters, including:
The unit measures the following instantaneous quantities:
The following voltage and current transformer tests are available with the optional Smart Probes:
Voltage Range (direct connect): Standard: 65, 110, 230, 300 V ac Other ranges on request
Current Range (direct connect): Standard: 0.02, 0.1, 1, 2, 5, 10 A ac Other ranges on request.
Frequency range (fundamental): 45 – 65 Hz
Auxiliary supply: 18 – 24 V dc
Display: 480x800 7‘‘ TFT touchscreen
Housing: Robust ABS case
The METES 325 implements the KoCoS SmartProbe technology in a wide range of external sensors. These sensors are ratio and phase error compensated over their entire measurement range.
Three Phase Energy Meter Calibration Verifier
Portable, three-phase energy meter calibration verifier. This unit is primarily intended for the verification of electronic and Ferraris energy meters, specifically aimed at the growing pre-payment energy meter industry in developing and first-world countries.
Energy Meter Verification
Full functionality for energy meter verification of calibration errors with direct percentage error read-out.
The unit measures and displays the system Voltage, Current, Angle and Power quantities. (W, var & VA) Per phase and total quantities.
The unit comes complete with three current clamp- on sensors for easy integration into the power network. The current clamp-on sensors have larger than usual installation maximum conductor diameter capability of 15 mm.
Easy menu driven interface for the entry of test parameters and display of test results using touch display.
This unit allows you to save all readings and test results in an on-board database for later downloading to the supplied PC software for report printing and archiving. Customer, Site and test results information is stored.
This unit has an optional Bluetooth wireless printer for onsite printing of the test result. The printer is battery powered using rechargeable on-board batteries
Current ranges of 200A, 500A and 1000A are available.
