Siemens SIMEAS P Power Meter

SIMEAS P is a power meter for panel mounting with graphic display and background illumination. The major application area is power monitoring and recording at MV and LV level. The major information types are measured values, alarms and status information. Power monitoring systems with SIMEAS P, a permanently installed system, enables continuous logging of energy-related data and provides information on operational characteristics of electrical systems. SIMEAS P helps identify sources of energy consumption and time of peak consumption. This knowledge allows you to allocate and reduce energy costs.
Measured values include r.m.s values of voltages (phase-to-phase and/or phase-to-ground), currents, active, reactive and apparent power and energy, power factor, phase angle, harmonics of currents and voltages, total harmonic distortion per phase plus frequency and symmetry factor.

This digital power meter for panel mounting can be used in Measurement Circuit for 3-phase AC Power.

The SIMEAS P comes with two binary outputs, which can be configured for energy pulses, limit violations or status signals. The unit is also able to trigger on settable limits. This function can be programmed for sampled or r.m.s. values. SIMEAS P generates a list of minimum, average and maximum values for currents, voltages, power, energy, etc. lndependent settings for currents, voltages, active and reactive power, power factor, etc. are also possible. In case of a violation of these limits, the unit generates alarms. Up to 6 alarm groups can be defined using AND/OR for logical combinations. The alarms can be used to increase counter values, to trigger the oscilloscope function, to generate binary output pulses, etc. The inputs and outputs of the Simeas P Power Meter are shown on Picture 2.
