MR660 Multi-Axis Fiber Optic Accelerometer

Multi-Axis Fiber Optic Accelerometer System

Power transformers often take the brunt of an overload Condition. They are the most likely to be damaged without the appropriate control and protection.
Weidmann InsuLogix® T is designed to measure transformer winding hot spots in real time. The drift-free, re-calibration free and maintenance-free InsuLogix® T allows an optimized operation of the transformer at safe load capacity during normal and emergency conditions.
