How Does a Power Logger Work?
Power loggers utilize clamp-on current sensors and voltage probes to measure electrical signals without interrupting the system. The data is converted into digital information, stored in internal memory or SD cards for future retrieval. Advanced microprocessors analyze the captured waveforms to calculate power, energy consumption, and other key parameters.
These devices can sample data at frequencies ranging from 1 to 10 kHz, making them capable of capturing transient events. Wrindu’s power loggers feature proprietary algorithms that provide highly accurate power factor and energy calculations. The data is easily exported via USB or apps, facilitating convenient PC-based analysis. Wrindu also offers OEM modifications to meet the specific needs of B2B customers, such as those in the railway or solar farm industries.
