Overcurrent protection guards against equipment damage from excessive heat. Instantaneous protection (50) trips based on current exceeding pre-programmed value. Time protection (51) trips based on current magnitude and duration
Spark gap consists of two electrodes separated by gas-filled gap. Electric spark forms when potential difference exceeds gas breakdown voltage. Ionization of gas causes current flow until path breaks or current drops. Light comes from material medium fluorescing in response to electron collisions
ICCP protects vessels from seawater corrosion using sacrificial anodes. System connects to vessel management system for remote monitoring. Protection adapts to changing water conditions
Insulated Headlights recommended for electric anomalies in early zones. Armored Headlights preferred in Deep zone due to explosive anomalies. Lead-Plated body parts recommended for radiation damage. Armored parts can be mixed with Lead-Plated for different zones
CV90 is a family of armoured combat vehicles developed by BAE Systems and Saab Bofors. Development began in 1984 for Swedish Army requirements. Production started in 1993, with over 1,300 vehicles delivered by 2021. Currently in service with seven countries including Sweden, Norway, and Finland
Current transformers measure electrical parameters and detect faults. Accuracy classes are designated by IEC and ANSI standards. Three main classes: Metering, Protection, and Special Protection
