Direction Of Current Indication TRIZ Cases
- DC Load Zone Fault Localization Using Fuse Voltage Sensing
Voltage sensing across branch fuses pinpoints a faulty DC load device even when the electronic switch disconnects before the fuse trips.
- Earth Fault Direction Detection in High-Impedance Grounded Feeders
Combining harmonic active and reactive residual current components lets an IED determine earth fault direction without angle-based maloperation.
- Battery Cell Voltage Sensing Circuit for Reverse Voltage Detection
Separate positive and reverse voltage sensing circuits cut circuit area and complexity while preserving battery cell measurement precision.
