Description
Tester function:
The tester is used for MCCB standard action test. When input 1.*5
times
of current into respective poles of MCB, no trip in 2h(ln*3A,
1h),
immediately higher current up to its 1.3 times, trip within
2h(ln<*3s,1h) .
Controlled by computer,the MCCB standard tester starts
testing according
to parameters
setted, judge qualified situation,reserve result and build
database.
