    Based on the quantity and criticality of Sulfr hexafluoride breakers, Siemens determined that this would be the most applicable medium and circuit breaker to inspect utilizing DR. Siemens typically performs several radiological exposures per phase to ensure that critical components are revealed. This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class sf6 gas dead tank breaker, two to three exposures per phase are required to provide adequate data.
