Ground Fault Sensor Market Segmentation:

Product Segment Analysis

In ground fault sensor market, DC segment is poised to dominate over 60% share by 2035. The segment growth can be attributed to the increase in demand for DC ground fault sensors in commercial and industrial applications, as they are more reliable and accurate than conventional sensors. Furthermore, the low line resistance and high DC link capacitance of DC microgrid lead to a significant rise in current. It could result in an unwanted resource disconnection during fault conditions, rendering the system unreliable. To investigate and overcome the aforementioned obstacles, an accurate and quick operating protection plan is required.

The rise in demand for DC loads in commercial, industrial, and residential settings has led to a predominant occurrence of renewable energy sources (RES) in today's power systems. Power electronic converters in the DC microgrid can readily interface with sources, loads, and energy storage devices like batteries and supercapacitors.

Application Segment Analysis

In ground fault sensor market, power segment is estimated to account for around 40% revenue share by 2035. The segment growth can be owing to the increased adoption of renewable energy sources, such as solar and wind, which require power applications to monitor and protect equipment from ground faults.

PV array ground faults are typically caused by errors committed during installation or by the mechanical, electrical, or chemical deterioration of photovoltaic (PV) components. The position and impedance of a defect define its type, and depending on these two characteristics, the fault's influence on array operations can vary greatly in severity.

In contrast to resistance-grounded or solidly grounded systems, ungrounded systems require a distinct approach to ground fault monitoring solutions.  The ideal practice for unground systems is to continuously check the insulation system's "strength" to ground, even when the system is in use.
