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” later in this
section for a description of these items. For troubleshooting and
diagnostic procedures, refer to Section 7, Troubleshooting and
Adjustments. Those unfamiliar with the function of rectifier
controls and indicators should read Section 2, Product
Description.
Precautions
When working on power systems, observe safety precautions 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.
•
Remote sensing of rectifier output occurs via the plant
control cable connected to P2A on control board CM2. This
cable must be disconnected when internal sensing is
desired, as when testing off line, using a test load.
