With digital circuit protection technology a large number of features, measurement data & useful information can be generated within circuit protection device's.
The problem of cost effectively accessing this data whilst operating within the requirements of the industry standards is providing a substantial barrier to the commercialisation & further uptake of digital circuit protection technology.
US7436641 Holley et al discloses a solution to this problem with a plug in diagnostic module for an intelligent circuit protection device aimed specifically at aircraft circuit protection & diagnostics. However, this disclosure has a number of differing & separate components linked together by cables & does not provide a compact solution that is contained within the front part size limits typical of standard circuit protection device's. Furthermore, this disclosure is intended for post diagnostic analysis of data when the circuit protection device is not powered.
A further problem associated with analogue circuit protection device's is the difficulty to automatically or remotely set or reset the circuit protection device in a cost effective manner whilst meeting the requirements of the industry standards & maximising the space utilisation within a given installation. EP1870919 Colombo, Ascari, Morlacchi et al disclose an embodiment to address this problem which involves an additional device mounted to the side of the circuit protection device thus taking up valuable installation space & involving skilled personnel.
