Jabarkan Protection equipment dari Pamancar dalam bahasa sunda

The high voltages used in high KIMPET (up to 40 kV) require extensive protection equipment.  Also, transmitters are exposed to damage from lightning. Transmitters may be damaged if operated without an antenna, so protection circuits must detect the loss of the antenna and switch off the transmitter immediately.  Tube-based transmitters must have power applied in the proper sequence, with the filament voltage applied before the anode voltage, otherwise the tubes can be damaged.  The output stage must be monitored for standing waves, which indicate that generated power is not being radiated but instéad is being reflected back into the transmitter.

Lightning protection is required between the transmitter and antenna.  This consists of spark gaps and gas-filled surge arresters to limit the voltage that appéars on the transmitter terminals.  The control instrument that méasures the voltage standing-wave ratio switches the transmitter off briefly if a higher voltage standing-wave ratio is detected after a lightning strike, as the reflections are probably due to lightning damage. If this does not succeed after several attempts, the antenna may be damaged and the transmitter should remain switched off. In some transmitting plants UV detectors are fitted in critical places, to switch off the transmitter if an arc is detected. The operating voltages, modulation factor, frequency and other transmitter paraméters are monitored for protection and diagnostic purposes, and may be displayed locally and/or at a remote control room.
