Bus Voltage Monitoring

Multi-Point Bus Voltage Monitors with Trip Outputs

Multi-point bus voltage monitors are electrical protection assemblies that measure electrical potential across twenty power bus segments to directly trigger load-shedding and circuit isolation. Constructed from precision voltage dividers, radiation-hardened operational amplifiers, and hardware comparators, the two-kilogram subsystem operates on three watts of power with 0.5 percent measurement accuracy. Because electrical stability is critical to lunar life-safety systems, the monitor bypasses central processor intervention entirely, executing hardware trips within one millisecond. To prevent spurious trips caused by space radiation while ensuring continuous fault detection across a 25-year operational lifetime, the subsystem employs multi-threshold trip points and voting logic across redundant sensors.

Voltage monitors at every bus segment with hardware trip outputs feeding load-shed and isolation circuits.
