2000 50A Ferroresonant Rectifier J85502B-1
6 - 2 Testing
Issue 6 May 1999
Tools and Test
Equipment
The following items are needed for testing the rectifier.
•
DMM (Digital Multimeter) Fluke 8060A or equivalent
meter having 0.02 percent accuracy on dc scale
•
Battery Plant Simulator Test Set, customer constructed, or
equivalent (see Figure 6-1)
•
DC dummy test load, 26-volt (24-volt rectifier) or 52-volt
(48-volt rectifier) with adjustment to provide a load of 60
amperes, 120 percent of the rectifier’s rating
•
Jeweler's screwdriver for adjusting potentiometers
•
Straightened paper clip inserted in eraser of wooden pencil
Battery Plant
Simulator Test
Set
The Battery Plant Simulator Test Set is a convenient tool used to
isolate communication troubles between the plant controller and
the rectifier. It simulates the plant controller relative to receiving
signals from, and sending signals to, the rectifier. If there is a
problem and the rectifier works properly with the test set, the
problem is either at the controller or in the interface wiring (plant
cable). Figure 6-1 shows how to construct a test set and cable.
Warning
Do not turn the DC OUTPUT circuit breaker On, close an
external charge circuit breaker, or install an external
charge fuse until told to do so.
