Electronic three-phase meter for commercial
and industrial customers
With the deregulation of the energy market, in
combination with a changing cost situation, new
flexible tariff structures and a modern energy
management are required. Remote metering and
the standardization process become more and more
important. With the adaptation of the alpha meter
A1500, the conditions to match these new
requirements were created.
The alpha meter is available either for direct or CT
connection and CT/VT connection. The meter is in
accordance with the relevant DIN and IEC
standards and follows the requirements of VDEW
V2.1 for electronic electricity meters
