A power logger is a device designed to measure and record electric power consumption. Power loggers are offered as products by manufacturers of measurement instruments and are equipped with memory to store power data while simultaneously displaying it.
The unit of electric power measurement is typically in kW (kilowatts) or W (watts), and this information is displayed on the device's interface panel.
Some power loggers provide the option to choose different sampling rates, with some offering high sampling rates, such as up to 100 times per second (100 Hz).
A variety of power logger models are available, and the appropriate instrument should be selected based on the required measurement accuracy.
Power loggers are primarily used for the measurement of electric power consumption. Most power loggers are compact and portable, making them convenient for field use in various applications.
Specific examples of their usage include:
Power loggers can be broadly categorized into two types: direct power measurement devices and indirect power measurement devices.
Both types are equipped with an interface panel for real-time data monitoring, displaying power values, typically in kW (kilowatt) or W (watt). In some cases, mW (milliwatt) units are used for precision measurements. Users can configure parameters such as sampling rates and recording formats on this panel. Higher sampling rates allow for finer data resolution, but they may limit the duration of data storage.
Recording media, such as USB flash memory or SD cards, are commonly used. Data is often stored in CSV or TXT file formats. Since analog signals are used for input data, measurement accuracy can be affected by noise. It is essential to implement noise-reduction measures, such as shielding, to enhance measurement precision.
Direct power measurement devices come with a clamp meter for measuring current and an alligator clip cable for measuring voltage. They measure and record power based on current and voltage readings. In the case of a 3-phase power supply, two clamp meters and three alligator cables are used.
For single-phase power measurement, one clamp meter and two alligator cables are typically employed. Most direct power measurement devices can simultaneously record voltage and current along with power data. Some devices can also measure reactive power and power factor simultaneously.
When using direct power measurement devices, the maximum measurable voltage is determined by the device's specifications. It is essential to confirm this limitation before making a purchase. If measuring high-voltage power is required, it may be necessary to use an instrument transformer to step down the voltage and then multiply the measurement result by the transformer ratio.
Indirect power measurement devices record power signals that have been converted by power transducers or similar devices. Typically, the input signal is an analog signal, such as 0-5 VDC or 4-20 mA DC. The maximum measurable value is determined by the range of the power transducer.
