12. Typical Applications
Measuring the contact resistance of circuit breakers.
Measuring Circuit breaker resistance is very important. If the
resistance of a circuit breaker become too large, than, the current
going through will warm up the circuit breaker (RxI
2
) and it could
start a fire. If the resistance is too high, the power transferred to the
load could be too low and the load could malfunction.
Measuring the bonding of welding points.
Welding point or good connections are the basic of good earthing
and continuity in electrical wiring. This is specially true for protection
conductors. For example lightning protection conductors requires
extremely low resistance to conduct the lighting into the earth.
On aircrafts, the lightning must be conducted from one side to the
other side of the wings by low resistance conductors, instead of
going through the frame of the plane.
These resistance can be checked with this instrument.
Measuring the contact resistance of bolted conductors.
Similarly to bonding of welding points, some times, connections are
done using bolted conductors or using bolted lugs. These contact
resistance can be tested and measured with this instrument.
Measuring the copper resistance fo transformers.
The low resistance of transformer winding can be measured with this
instrument, to ascertain the ohmic component of the winding.
Measuring the earthing conductor resistance.
Earthing conductor Resistance is one of the most important
component of an electrical protection system. The measurement of
its value can be done using this instrument.
