Span Sentry provides an accurate, real-time estimation of the ampacity (current carrying capacity) of transmission conductors for a maximum operating temperature.

Incorporating multiple on-site sensors, Span Sentry monitors conductor clearance, line current and weather conditions to calculate conductor ampacity, temperature and tension.

This summary information is provided in real-time to EMS operators in order to more efficiently manage their transmission network, particularly in high load and contingency situations.
