Integrated Optical Voltage Measurement System

Srico, Inc.

Columbus, OH

Voltage sensor probe that allows isolation from electromagnetic interference by converting the electrical signal to an optical signal

• Integrated optic high voltage probe with optical signal transmission, eliminates the need for high voltage leads from source to readout
• Optical isolation reduces the safety problems associated with high voltage
• The problem of electrical noise and electromagnetic interference was eliminated as well as problems associated with vibration
• Improved measurement accuracy

• Large scale production of an inexpensive robust probe will be initiated
• Received $80K of Phase III funding from Garrett Morgane
• Electrical distribution companies will use this system in their power distribution facilities

• Well suited to NASA’s stringent requirements for automatic control of aeronautic or space power management and distribution systems
• Kennedy Space Center - for lightning and thunderstorm detection
• Space station power system
• Electromagnetic compatibility testing
• Physiological monitoring of astronauts
