METES - Meter Test Systems
Dramatic advances in the field of measurement technology and the use of state-of-the-art micro-electronics have led to the development of a new generation of electricity meters which are far more accurate than their predecessors of just a few years ago. As well as measuring the exact amount of energy used, a high level of integration enables electronic meters to perform a number of additional functions. As a result, these meters are also more sensitive to network irregularities. This means that regular testing is the only way to ensure that a meter functions correctly, both during final factory tests and during the entire life span of a meter.
For this reason, it is no longer enough for modern meter testing equipment to measure metering accuracy alone; meter test systems must also be able to measure the power quality of a network extremely precisely. The latest generation of METES test systems unite the functions of conventional meter testing equipment with the properties of a power quality analyser in a single system. The measured values can be used as the basis for the calculation and analysis of a multitude of electrical variables, including the full complement of power quantities, DC content, harmonics and flicker analysis.
As a result, the meter test systems of the METES range are well-equipped to deal with both present and future requirements in the area of meter testing.
METES 340REF - High-Precision Meter Test System
The meter test systems of the METES range can perform all manner of tests on electricity meters quickly, efficiently and extremely precisely.
METES 340 REF is the new benchmark for on-site tests related to the installation or inspection of electricity meters. Automated test procedures can either be provided via a PC installed with ergonomically designed software or can be run by means of menus displayed on the built-in screen.
For the purpose of comprehensive analysis, the latest version of the METES software can not only measure meter accuracies but can also record signal shapes and other quantities related to power quality.
