An essential disadvantage of Intrinsic Safety type of protection is the low consumption of effective power of mostly less than 2 W. PTB-basic research showed that – with utilization of specific physical ignition effects – a significant increase of power, up to approx. 50 W, is possible.Working group 3.62 focusses on the industrial implementation of these problems and the integration in the international standardization (EN and IEC).
