How much torque is needed in order to get a bushing well insert into a bushing well?
In order to get a bushing well insert into a bushing well, 15 ft-lb of torque is needed
Why is the use of a drain wire important?
Drain wires prevent the accumulation of charge on the component shield by draining the charge to ground
What is the purpose of lubricating separable connectors?
Lubrication makes initial installation easier and helps make future operations less forceful
Why is cleanliness so important when involving an external surface?
Leakage current can increase when external surfaces experience conductive contaminants. This can result in an increase in power loss and cause higher operating temperatures
What kind of grease should be used with separable connectors?
A silicone grease designed for use with separable connectors
Why is a tight fit along the mating face important?
A tight fit helps keep moisture out and dielectric strength high
Why is it important to pull elbows fast?
Slow switching speed can result in arcing across the mating contacts and eventually damage the contacts from the ionized gases expelled into the interface. This could affect the connector’s ability to provide a complete electrical path
What affects the life of a loadbreak connector?
Many variables affect the life of connectors including the number of operations, magnitude of current interrupted and phase angle
Why is it important to keep test points capped?
A contaminated test point can erode the surrounding insulation and lead to a connector failure
How many fault close operations can a separable connector perform?
Loadbreak separable connectors are limited to a single fault close event because arcing can vaporize metal from the contact surfaces and erode arc-quenching materials within the conductor
