WebDec 1, 2024 · High Voltage Circuit Breaker Static Resistance Measurement with Both Sides Grounded. During the HV circuit breaker contact resistance measurement, an efficient way of ensuring protection from the inducted voltages is to ground the tested circuit breaker on both sides. This will ensure the safety of the operators and protect the … consultancy 2 framework WebFirst: Prepare the Junction. The first step in measuring the contact resistance of a metal-semiconductor junction is to deposit the metal on the semiconductor and pattern it so that you have lots of identical pads spaced varying distances apart. This is an example of the metal pattern. Ideally, the pattern includes many rows of various pad sizes.
