Abstract:
1. An intelligent electronic device (IED) configured to provide a protective function to a power system, comprising: a first input configured to receive measurements of a first stimulus type from the power system; a second input configured to receive measurements of electro-optical (EO) radiation from the power system; a conversion element configured to determine quantized analog measurements corresponding to the measurements received via the first and the second inputs; a computer-readable storage medium configured to store the quantized analog measurements; a data output configured to export the quantized analog measurements from the computer-readable storage medium; wherein the IED is configured to cause EO radiation to be emitted in the vicinity of an EO radiation collector communicatively coupled to the second input, and wherein the IED is to determine an attenuation of the EO radiation collector based upon quantized analog measurements determined from EO radiation measurements received responsive to the emitting.
