POWER ME TERS Easy insight into power consumption

Electricity: an expensive source of power Monitoring the energy usage of a factory is a powerful tool and key to maximizing energy savings. Energy consumption data provides insight for accurate cost allocation, and in identifying areas of improvement to lower energy consumption and to increase performance. Implement complete power metering solutions to keep a close eye on all your energy consumers, circuit by circuit, like compressed air systems, vacuum systems, HVAC systems, cooling water stations, lighting and more.

Measuring power consumption with VPInstruments VPInstruments offers two types of meters to measure power consumption: the VPInstruments 3 Phase Power Meter that measures true power and the VPLog-i that measures current consumption. Our solution cover a wide range of power meter applications in the industry. Applications > Power consumption of large consumers (i.e. compressors, dryers, pumps, water chillers) > Submetering > Cost allocation > Baseline condition monitoring > Energy management > Efficiency calculations (i.e. compressor electrical usage vs output) 3 Phase Power Meter vs. VPLog-i...

With the VPInstruments 3 Phase Power Meter you can measure the voltage and current of all three phases. It provides power, voltage, current, cos(phi) and many more electrical parameters via the RS485 (Modbus RTU) interface. The Modbus interface allows the meter to be easily connected to a monitoring system. And when combined with one or more flow meters, you can monitor compressor efficiency in real-time. > True RMS power measurement of single-phase or three-phase systems > One size fits all: one model for 100 to 600 Vac, 50 / 60Hz > RS485 (Modbus RTU) output > Wye or delta in one model >...

Order codes Selection is easy due to the wide voltage range of the 3 Phase Power Meter. The same meter can be used for all nominal voltages between 100 Vac and 600 Vac, for delta and wye configurations at 50 Hz or 60 Hz. In addition, you will need to specify a current transformer (CT) for each phase. For delta systems you may only need two CTs. To determine your size of current transformer, check the maximum amperage and be sure to account for the input power factor (cos(phi)), minimum input voltage and other factors. The 3 Phase Power Meter is compatible with VPInstruments' current...

Power measurement examples Efficiency calculations Monitor the efficiency of a machine by comparing input and output. For instance, the efficiency of a compressor can be measured by combining a power meter with a flow meter. By monitoring this KPI continuously, you will be able to see changes in efficiency due to e.g. internal mechanical wear, a change of inlet conditions, fouling, a malfunctioning drain, and other maintenance issues. Efficiency Flow meter Compressor efficiency is indicated by a typical Key Performance Indicator (KPI) with units of kW/m3n/min or kW/100 SCFM. Baseline...

Submetering Submetering gives the ability to monitor departments, processes, or individual pieces of equipment. You can collect actual, real-time energy consumption data, rather than estimating. It provides the granular in-depth information needed to make the right optimization decisions and it allows for cost allocation.

" ower measurements combined with flow measurements, P showed that the efficiency of our compressors was lower than thought, ranging between 7 to 8 kWh/m3/min. As an efficiency of 6,18 kWh/m3/min is possible, the savings potential is 15%!”

VPLog-i The VPLog-i is a Rogowski type coil that measures AC currents (true-RMS on a single-phase power cable). The VPLog-i is very easy to use; just wrap around one of the three-phase power cables and close the snap fitting. The LED provides feedback. The VPLog-i offers the best solution for power measurements in audits. The sensor can also be used for permanent installation. In this case, cos(phi) has to be estimated, and voltage needs to be measured once. These parameters are used to calculate the estimated power consumption. In VPVision, you simply enter these numbers in the power meter...
