    SURGE SUPPRESSION FOR ZONE 0 LOCA TIONS tal requirement of all the methods of protection used for power equip- ment. It is not usual for lightning induced current to directly cause enough heating to create a hazard by temperature ignition, since the current pulses are too short to create a sustained high temperature. However , vapourisation of flim ...

The diagram shows a two wire 4 to 20 milliamp transmitter with internal isolation fed from a galvanic isolator . T o establish the order of the problem some assumptions are made which cannot be fully justified but are believed to be reasonable. These are: a) The ...

    4 PROTECTION OF THE SENSOR AND TRANSMITTER The problem of surge protection of the transmitter and sensor is rela- tively easy to solve since it is only necessar y to prevent significant voltage differences so as to avoid ignition capable sparks. This can be achieved by using a combination of surge limiting devices, which ef- fectively control the v ...

    The system should be designed so that when the surge current is di- ver ted the voltage drop across the bonding conductor does not create a large voltage across the isolator . Figure 4 gives an illustration of a satisfactor y system. With the currents and distances indicated the iso- lator is still subjected to a 1.5kV pulse and hence the importanc ...

    supply will contain a significant amount of surges but if for any reason the supply is particularly exposed to invasion from lightning induced surges then some consideration to suppressing the main supply should be given. A practical economic solution is to protect the supply input to the com- puter system as indicated in figure 5. A similar argume ...
