A method for detecting heater disconnection by measuring power factor and its application in detecting phase loss operation of inverters is proposed!
This document is a technical material about "Heater Open Circuit Detection." Even when the load is resistive, if the current is unbalanced, the power factor decreases. By measuring the power factor rather than the magnitude of the current, it becomes easier to detect abnormalities in the equipment. SIRC's power sensor can easily measure not only the current but also the power factor by simply clamping two sensor heads onto two wires, allowing for the detection of abnormalities in the equipment.

Company information
SIRC Corporation provides IoT sensors that can be retrofitted to existing equipment without large-scale construction for factories and plants. The main products include the "IoT Power Sensor Unit," which allows for easy measurement of power consumption for each piece of equipment and can be installed in about 15 seconds, and the "IoT Angle Sensor Unit," which can convert existing analog meters into IoT devices. Additionally, SIRC has developed its own cloud service, "SIRC Cloud," to visualize this data and support centralized management of on-site data. SIRC supports "on-site DX" that can be initiated while valuing and making the most of existing equipment.
