Power View ITS (Immersed Tank Sensor)—a flange-mounted, maintenance-free online DGA monitor that measures hydrogen, temperature, moisture directly in the transformer tank ( sensor at the tip of the long probe 250mm for fastest response) no moving parts, consumables, or recalibration,  built for a 15-year service life. It can be installed Installs quickly on any valve flange and the probe slightly penetrates tank (sits in moving oil) for the fastest reaction to fault development—the key advantage of true immersed sensing. Start lean with H₂ + temperature as an early fault indicator, then field-upgrade to full DGA only where needed (aligning with CIGRÉ TB783 guidance) to optimize spend. Ultra-long-range communication helps monitor assets spread across plants or remote sites without new cabling. It also comes with Modbus RS-485 with optional IEC 61850, plus available analog outputs, and relay contacts. Substation Digital for automated diagnostics, risk assessment, alarms, and reports
