- TNV(telecommunication network voltage)circuit
1.2.8.11TNV-1 circuit whose normal operating
voltage do not exceed the limits of SELV and on
which overvoltages are possible. - 1.2.8.12TNV-2 circuit whose normal operating
voltage exceed the limits of SELV and which is
not subjected to overvoltages. - 1.2.8.13TNV-3 circuit whose normal operating
voltage exceed the limits of SELV and on which
overvoltages are possible.
31TNV??????
- The signal of TNV circuit mainly is from the
telephone line outside. - The cause of the overvoltage mentioned in the
above page - 1,telephone line maybe contact with the high
voltage electric power line out side - 2,maybe from the lightning
- In this type circuit like TNV-2
- The telephone we often use belong to the
TNV-3 - NoteCable distrebution systemTNV-1
- A metallically terminated transmission medium
for transmission of video and/or audio signals
between separate buildings or between outdoor
antennas and buildings.
