2/4 S110 Power and Energy Meter Benefits Compressor Rogowski Coils Filter Convenient and easy to set up compressor performance and efficiency monitoring Real power consumption in kW and kWh by measuring each phase voltage and current DIN rail installation for power cabinets or portable version with rugged housing Power range up to 2 MW (2000 kW) Three current sensor models with 100 A, 1000 A or 3000 A available In this illustration, a Power and Energy Meter is installed directly into the connection box of the compressor. The Rogowski current coils are easy to install, by just clamping them around the power cables. The voltage connection can be drawn directly from the power cabinet of the compressor. The Power and Energy Meter is then connected to a S330 / S331 Display and Data Logger to record the Voltage and Current of each phase, as well as recording the actual power consumption and the total energy consumption. This is not only used to identify inefficient compressors, but also letting the compressed air operator know what the real costs of the compressed air are. The SUTO Power and Energy Meter has been designed with a focus on easy installation and reliable measurements. The main application is to measure the power consumption and the accumulated energy consumption of electrical 3-phase consumers, like compressors, driers and oxygen/nitrogen generators. The main difference to common power measurements is that all relevant parameters are real measured values and not assumptions. Unlike the traditional method, where only one phase is measured, the voltage is assumed as stable and the phase shift is entered as a constant, the S110 measures the voltage and current of each phase. By this, the S110 is much more accurate and delivers more reliable measurements compared to single phase current measurements.
