Enabling Technology: Optical-to-electrical power conversion; analog signals converted to digital format on HV line and transmitted to control room via fiber optic line (or optionally over a wireless connection)
Fiber-Optic Cable -optic cable systems provide two principal benefits. First, the signals within fiber-optic cables are immune to RFI and electrostatic interfere e that can disrupt
This solution uses traditional T1 metallic delivery in the substation environment (Class B) and any transfer trip circuits delivered via this traditional method (Option 3) MUST be configured to trip the
The process level is the interface between primary and secondary (protection and control) equipment. In a conventional substation, the interface is hard-wired with copper cabling; currents and voltages are
Starting from high sensitivity signal sensing and other aspects, the system develops high-precision online temperature signal recognition technology
The intelligent identification of potential grounding hazards for the OPGW (optical fiber composite overhead ground wire) fiber composite overhead ground wire in a substation is designed.
The stability of optical fiber communication is a key factor to ensure the performance of the protection devices on both sides, but the abnormal detection of optical fiber multiplexed channels
