What Are Power Loggers?
Power Loggers are devices that measure and record electric power. Power Loggers are sold as products by manufacturers of measuring instruments and store power in memory while measuring and displaying power.
The unit of electric power is mainly kW (kilowatts) or W (watts), which is displayed on the interface panel.
Some products offer a choice of sampling rates, with some having sampling rates as high as 100 times/second (100 Hz)
Various types of Power Loggers are available, and the appropriate instrument should be selected according to the measurement accuracy required.
Usage of Power Loggers
Power Loggers are mainly used to measure electric power. Most power loggers are small enough to fit in a handbag and are carried around for use in most cases.
Specific examples of use include the following:
- Confirmation of trial operation during electrical work
- Maintenance of production equipment
- Temporary power measurement for industrial machinery management
- Power measurement of electronic equipment in general households
- Power measurement of lithium-ion battery packs
- Battery management systems in electric vehicles
Principle of Power Loggers
Power Loggers can be broadly classified into two types: direct power measurement devices and indirect power measurement devices.
Each has a different mechanism. The common point between the two is that most of them are equipped with a panel for interface. The panel allows the user to check the measurement results in real time.
The display unit is mainly kW (kilowatt) or W (watt). For fine power measurement applications, mW (milliwatt) is sometimes used. Sampling rate and recording format can also be set on this panel in most devices. Higher sampling rates allow finer recording, but you will not be able to save long-term records.
USB flash memory or SD cards are used as recording media. CSV and txt files are often used as the output format. Since analog signals are used as input data, measurement results may not be accurate due to noise. In order to improve the detection accuracy, it is important to take measures such as removing noise from the wiring route to prevent noise from entering.
1. Direct Power Measurement Device
The direct power measurement device comes with a clamp meter for current measurement and an alligator clip cable for voltage measurement. Measure and record power from current and voltage. A 3-phase power supply can be measured by using 2 clamp meters and 3 alligator cables.
For power measurement of single-phase power supply, one clamp meter and two alligator cables are used. Most devices that directly measure power are capable of recording voltage and current simultaneously with power. Some products can also simultaneously record reactive power and power factor.
When measuring direct power, the upper limit of the voltage that can be measured is determined by the device. You must confirm this before purchasing the device. If you wish to measure high-voltage power, there are no commercially available Power Loggers that can measure Measure via an instrument transformer and multiply the measurement result by the transformer ratio.
2. Device to Measure Power Indirectly
Indirect power measurement devices are products that record power signals converted by power transducers or other devices. Generally, the input signal is an analog signal such as 0-5 VDC or 4-20 mA DC. The maximum measured value is the span value of the power transducer.
