9.8 Recall a Breaker Test Plan

A breaker test plan contains breaker maximum/minimum operating parameters. A typical list of

operating parameters is shown as follows:

„

Max/Min Contact/Resistor Trip Time.

„

Max/Min Contact/Resistor Close Time.

„

Max Contact Spread Time.

„

Max Resistor Contact Spread Time.

„

Max/Min Stroke.

„

Max/Min Trip Velocity.

„

Max/Min Close Velocity.

„

Max/Min Over Travel.

„

Max/Min Bounce Back.

„

Trip Analysis Points.

„

Close Analysis Points.

By recalling a Test Plan before testing, a user doesn't have to set analysis points to calculate

the Trip or Close velocity of the circuit-breaker contacts. Since a Test Plan contains other breaker
test parameters, the test report also displays a Pass/Fail status for each parameter tested.
