The DC system in operation should be continuously monitored to ensure safe and reliable performance. Here are the key areas that require attention:
    (1) Insulation Monitoring: Regular checks of the insulation resistance between the DC system and ground are essential to detect any degradation or faults that could lead to short circuits or equipment damage.
    (2) Voltage and Current Monitoring: Keeping track of the DC voltage levels and current flow helps identify abnormal conditions such as overloads, under-voltage, or unexpected fluctuations that may affect system stability.
    (3) Signal Alarm Monitoring: System alarms and signals must be checked regularly to ensure they are functioning correctly. These alerts help in early detection of potential issues before they escalate into major failures.
    (4) Automatic Alarm Monitoring: Modern DC systems often include automated alarm features that trigger notifications when certain thresholds are exceeded. These should be configured properly and tested periodically for reliability.
    (5) Circuit Breaker and Fuse Monitoring: The status of DC circuit breakers and fuses should be inspected regularly to ensure they are in good working condition and can respond effectively during fault conditions.
By maintaining a thorough monitoring routine, operators can significantly reduce the risk of system downtime and improve overall operational safety.
