Testing
Introduction
This section gives test procedures for newly installed and/or
operating rectifiers. If the plant in which a rectifier is being
installed has never been operational, the plant and controller
tests must be performed before the rectifier tests. Consult the
plant and controller product manuals for their installation test
procedures.
Rectifiers can be tested on or off line. “On line” means a battery
string and/or office load is connected to the rectifier. A dummy
test load and a Battery Plant Simulator Test Set are required for
testing off line. See “Tools and Test Equipment” in this section
for a description of these items. For troubleshooting and
diagnostic procedures, see “Diagnostics and Troubleshooting”
in Section 7. Those unfamiliar with the function of rectifier
controls and indicators should read “Front Panel Controls and
Indicators” in Section 2.
Precautions
When working on power systems, observe the safety precautions
described in Section 4 and those within each procedure.
•
The ac input voltage powers certain control relays, the
Rectifier Failure Alarm (RFA), and the ac contactor.
Voltage is available to these circuits whenever the ac
service is available to the rectifier.
•
See Figure 5-4. Verify that the cables are connected
correctly for the desired output. Rectifiers that deliver
-48Vdc output require positive ground. Verify that the dc
output circuit breaker is open (off). For more complete
discussion of related issues, see “Converting DC Output
Polarity (Optional)” in Section 5.
