What it does

During dynamic braking the drilling motor acts as a generator and that energy has to go somewhere. The grid resistor bank dissipates it as heat. These assemblies live hard: thermal cycling, vibration, and weather. Failures are usually open elements, cracked grids, or degraded connections rather than anything subtle.
