Flexible and effi cient measurement

The extension board PM-2 allows cost-effective measurement of relevant pow-

er values in low and medium voltage systems.

Various measured values such as frequency, power and phase displacement

angle are directly available for the evaluation of the utilization of the equip-

ment, the evaluation of the quality and stability of the voltage as well as the

identifi cation of anomalies in the distribution network.

As an extension board for the net-line FW-5, the PM-2 is inserted into the I/O

area of the RTU. setIT offers the specifi cation of the measurement parameters

and the selection of measured values from V6.000. The values are integrated

directly in the process data from where they can be monitored, sent and recor-

ded based on custom criteria.

Typical application areas

• Local substations

• Decentralised power plants

• Systems with decentralised power distribution

• Industrial systems
