The DEWE-571-PNA was designed and developed for measurements in distributors and central control rooms.
This instrument is completely isolated, with the highest EMC protection and a stable case. If more channels are needed, then the ELOG model can be used. It has four voltages and 12 currents at the same time.
The DEWE-571-PNA performs power quality analysis following exact standards. The combination of high-capacity measurement software and flexible report generators enables the user to solve nearly every task in the field of energy measurement. The system is designed to fulfil the requirements of IEC-61000-4-30 class A, the power quality measurement standard.
Due to the liberalisation of power markets, grid-bound energy sources, such as electrical current, freely tradable products and have to adhere to product liability law, as do other tradable products.
The corresponding parameters were constituted in the product standard EN 50160 in Europe with major parameters:
- Wave form
- Three phases
Additionally, there are many other tasks, including special harmonics evaluations, long-term measurements and the identification of fastest transient processes or only power flow measurements in four quadrants.
