Transmission Technologies

Synchronous Switching Control

Switching control technology works to protect power transmission and distribution systems from switching-induced current spikes and over-voltages, increases equipment service life, extends inspection cycles and contributes to maintaining stable power networks.

Examples applications of transformer circuit breakersExcessive surge current/fluctuation of power line network system voltage,Improved power stability by limiting surge current

Supervisory System

Highly sensitive, highly accurate condition-based maintenance (CBM) sensors continuously monitor substation equipment for secular changes. An infallible early warning detection system, it aids in CBM by catching even the slightest of changes that may be overlooked during routine inspections.
