GE H201CI‑1‑Hydran Online Transformer Gas Monitor

1. Product Title

GE H201CI‑1‑ Hydran Online Transformer Gas Monitor

2. Product Overview

The H201CI‑1 is an online dissolved‑gas‑in‑oil monitoring unit built for power transformer condition assessment. It continuously tracks key fault gas concentrations and oil‑water content to detect early internal transformer degradation, minimizing unplanned outages in high‑voltage substations. H201CI‑1 delivers both analog and digital output signals to connect with SCADA and DCS platforms, removing manual sampling workload for maintenance crews. With robust electromagnetic interference resistance, this device works reliably in electrically noisy substation environments and supports configurable alarm thresholds for gas‑level events.
