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-
Network variables Frequency, 45 ... 66 Hz, resolution 0.001 Hz P, Q, S, error ±0.5% Energy W, Wb errors ±0.5%
Data range 47 measured values i.a. I, U, ULL, P, S, Q, W, Wb, f, PF 12 Single-point information: Faults, power load direction, rotary field errors 8 Counter values for power measurement 3 Single commands for acknowledgment
