Test 2: Leakage Current Test with Mains Voltage Applied (Sink) for Intraoperative Transducers
Key to Test 2 Diagram
C
Stray capacitance from the ultrasound system power wiring to the system
grounded metal chassis (1 to 3 MΩ reactance)
Z
Impedance between the metal parts of the transducer and a test electrode placed
in the bucket of saline solution (about 850 kΩ with an intact outer insulating layer,
500 Ω with a hole in the layer)
A
Microammeter to measure leakage current from a line supply to the transducer
and back to earth ground through electrode Z and the equipment chassis
e
Line power source, either 110 Vac or 220 Vac
