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.
