Means for sensing conditions in high potential region and for transmitting such intelligence by light means to low potential regions

Claim 1

A DEVICE FOR SENSING AN ELECTRICAL CONDITION IN A HIGH VOLTAGE ELECTRICAL POWER TRANSMISSION SYSTEM WHICH IS SURROUNDED BY A REGION OF HIGH POTENTIAL COMPRISING, A LIGHT SOURCE COMPRISING A SEMICONDUCTOR LOCATED IN SAID REGION OF HIGH POTENTIAL AND RESPONSIVE TO CURRENT TO PRODUCE A LIGHT SIGNAL AT A JUNCTION, A PAIR OF CURRENT TRANSFORMERS LOCATED IN SAID REGION OF HIGH POTENTIAL AND EACH INDUCTIVELY COUPLED TO SAID SYSTEM, ONE OF SAID CURRENT TRANSFORMERS PROVIDING BIAS CURRENT ENERGIZATION FOR SAID SEMICONDUCTOR WHICH CAUSES THE LATTER TO EMIT A QUIESCENT LIGHT VALUE, THE OTHER OF SAID CURRENT TRANSFORMERS PROVIDING A CURRENT OUTPUT WHICH VARIES AS THE TRANSMISSION SYSTEM CONDITION VARIES, SAID CURRENT OUTPUT ENERGIZING SAID SEMICONDUCTOR TO CAUSE ITS LIGHT EMISSION SIGNAL TO VARY ABOUT SAID QUIESCENT VALUE, LIGHT RESPONSIVE MEANS POSITIONED IN A REGION OUTSIDE OF SAID HIGH POTENTIAL REGION AND OPERABLE IN RESPONSE TO A LIGHT SIGNAL FROM SAID SEMICONDUCTOR TO PRODUCE AN ELECTRICAL OUTPUT SIGNAL IN RESPONSE TO THE VALUE OF SAID LIGHT SIGNAL, FLEXIBLE DIELECTRIC FIBER OPTIC LIGHT TRANSMITTING MEANS EXTENDING BETWEEN SAID SEMICONDUCTOR AND SAID LIGHT RECEIVING MEANS TO TRANSMIT THE LIGHT SIGNAL FROM SAID LIGHT SOURCE TO SAID LIGHT RESPONSIVE MEANS, AND MEANS RESPONSIVE TO SAID ELECTRICAL OUTPUT SIGNAL TO TRANSMIT THE LIGHT SIGNAL FROM SAID LIGHT SOURCE TO SAID LIGHT RESPONSIVE MEANS.

Claim 2

A DEVICE FOR SENSING AN ELECTRICAL CONDITION IN A HIGH VOLTAGE ELECTRICAL POWER TRANSMISSION SYSTEM WHICH IS SURROUNDED BY A REGION OF HIGH POTENTIAL COMPRISING, A LIGHT SOURCE COMPRISING A SEMICONDUCTOR LOCATED IN SAID REGION OF HIGH POTENTIAL AND RESPONSIVE TO CURRENT TO PRODUCE A LIGHT SIGNAL AT A JUNCTION, A PAIR OF CURRENT TRANSFORMERS LOCATED IN SAID REGION OF HIGH POTENTIAL AND EACH INDUCTIVELY COUPLED TO SAID SYSTEM, ONE OF SAID CURRENT TRANSFORMERS PROVIDING BIAS CURRENT ENERGIZATION FOR SAID SEMICONDUCTOR WHICH CAUSES THE LATTER TO EMIT A QUIESCENT LIGHT VALUE, THE OTHER OF SAID CURRENT TRANSFORMERS PROVIDING A CURRENT OUTPUT WHICH VARIES AS THE TRANSMISSION SYSTEM CONDITION VARIES, SAID CURRENT OUTPUT ENERGIZING SAID SEMICONDUCTOR TO CAUSE ITS LIGHT EMISSION SIGNAL TO VARY ABOUT SAID QUIESCENT VALUE, LIGHT RESPONSIVE MEANS POSITIONED IN A REGION OUTSIDE OF SAID HIGH POTENTIAL REGION AND OPERABLE IN RESPONSE TO A LIGHT SIGNAL FROM SAID SEMICONDUCTOR TO PRODUCE AN ELECTRICAL OUTPUT SIGNAL IN RESPONSE TO THE VALUE OF SAID LIGHT SIGNAL, FLEXIBLE DIELECTRIC FIBER OPTIC LIGHT TRANSMITTING MEANS EXTENDING BETWEEN SAID SEMICONDUCTOR AND SAID LIGHT RECEIVING MEANS TO TRANSMIT THE LIGHT SIGNAL FROM SAID LIGHT SOURCE TO SAID LIGHT RESPONSIVE MEANS, AND MEANS RESPONSIVE TO SAID ELECTRICAL OUTPUT SIGNAL TO TRANSMIT THE LIGHT SIGNAL FROM SAID LIGHT SOURCE TO SAID LIGHT RESPONSIVE MEANS.
