Siemens SICAM P55 Power Meter Device
SICAM P55 Power Meter Device is a power meter for panel mounting with graphic display and background illumination, or for standard rail mounting, used for acquiring and/or displaying measured values in electrical power supply systems. More than 100 values can be measured, including 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, energy output, as well as external signals and states.
Functions
- Measurement of voltage, current, active & reactive power, frequency, active & reactive energy, power factor, symmetry factor, voltage and current harmonics up to the 21st, total harmonic distortion.
- Single-phase, three-phase balanced or unbalanced connection, four-wire connection
- Communications: PROFIBUS-DP, MODBUS RTU / ASCII or IEC 60870-5-103 communication protocol simple parameterization via front key or RS485 communication port using SICAM P Manager software
- Graphic display with background illumination with up to 20 programmable screens
- Real-time clock: Measured values and states will be recorded with time stamps.1 MB memory management: The allocation of the non-volatile measurement memory is programmable.
- Recording and display of limit value violations and log entries.
- Battery: Recordings like limit value violations or energy counter values stay safely in the memory up to 3 months in case of a blackout.
P55 Power Meter Device Application Areas
Power monitoring systems with SICAM P55, a permanently installed system, enables continuous logging of energy-related data and provides information on operational characteristics of electrical systems. SICAM P helps identify sources of energy consumption and time of peak consumption. This knowledge allows to allocate and reduce energy costs.
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.
The input modules work with external signals with a measurement range of DC 0 – 20 mA. Mean values of all external analog channels as well as states of digital channels can be recorded and saved into the memory. All recorded quantities and binary state information can be “read out” and evaluated with the configuration software SICAM P Manager. Output modules can be used for conversion of any electrical quantity (current, voltage, etc.) into a DC 0 – 20 / 4 – 20 mA output signal, generation of impulses for metering, indication of limit value violations, as well as for switching operations.
Power Quality
Ensuring power quality in a phase of energy transition
Increasing power feed-in from renewable resources poses new challenges for municipalities and distribution system operators.
The stable supply of electric power is any grid operator? top priority. Utilities must adapt and optimize grid monitoring, control, and automation systems across all voltage levels to avoid power quality fluctuations and disturbances.
Power Generation
Maintaining control of distributed power producers?
Ensuring grid stability is becoming increasingly complex.
The vast number of small distributed power producers calls for new strategies to ensure consistent power quality. Identifying, locating, and eliminating disturbances and faults as well as the flexible, quick balancing of power production and load consumption require integrated hardware and software solutions that work smoothly together.
Transparency
More data, increased transparency
Modern electrical grid components deliver, process, and analyze data.
One consequence of digitalizing power grids is the steadily growing volume of captured data. Moreover, these vast quantities of data contain valuable information that describes the state of the grid, enables advanced computational analysis of changes, and can improve the performance and extend the service life of assets. The hardware and software from Siemens needed for this fulfills all the requirements.
CAPEX savings
Efficient grid expansion?
As a result, a combination of robust technology and digital innovations leads to increased efficiency. Maintaining or even increasing grid performance is becoming ever more challenging. However, with growing efforts, expenses also increase. Therefore, innovative technologies and smart data usage can help municipalities and DSOs manage these challenges and improve their competitiveness.
OPEX savings
Optimizing business operations?
Comprehensive and efficient ways for municipalities and DSOs to get the most out of their OPEX.
Furthermore, power systems can reliably meet the increasing electricity demand from industrial and residential consumers. Also, modern technologies and innovative solutions such as optimized voltage and capacity management, self-healing grids, and loss reduction support this.
Sudden connection of renewable energy sources and large loads causes voltage variations and supply dips that affect many electronic devices and automation systems in industrial plants. Moreover, the production systems themselves can also cause faults and feed them back into the distribution system. The risk? Plant shutdowns and production loss. The answer? Power quality. Continuous measurement and analysis of power quality enable early detection of unexpected risks. Explore the power quality and measurement products with us. Click here!
