[Factory Supply] Fault Indicator Optic PMMA OD2.2 Muti-Core X4 5M For Industrial Optic Cable, Machine Equipment
About this item:
Inner PMMA Diameter 1.0 And Outer Diameter 2.2mm, Failure Indicator
Basic principles:
❤ Short circuit principle: When the circuit has a short circuit fault, the short circuit sensor senses the fault current, and at the same time converts this signal into a data signal and sends it to the host, then the two-phase short circuit fault indicator on the host panel is on, showing the line where the fault occurred.
❤ Grounding principle: The grounding part is based on the detection of the zero-sequence current of the line. When a ground fault occurs in the system, if the grounding indicator on the panel is on, it indicates that the cable system has a grounding fault.
Application:
❤ fault indicator Indicator light shows bus grounding, single-phase short circuit detection, snap ring fixing
❤ belt hoop Installation location Power distribution equipment in power systems, oil fields, chemicals, steel mills, railways and other cable systems.
