INSPECTION
1.1. UNPACKING
When unpacking the unit, examine it carefully for any
shipping damage. The "Damage and Shortage"
instructions packed with the unit outlines the procedure
to follow if any parts are missing or damaged.

DESCRIPTION
2.1. GENERAL
WHR34*S*** Series STABILINE
®
Automatic Voltage
Regulators are three phase, 380Y/220 X 480Y/277 volt,
fast acting electromechanical regulators. These WHR
Series voltage regulators regulate one line-to-line
voltage and correct all phases by the same amount.
These voltage regulators are wye connected, have an
analog electronic control section, and have a power
section consisting of one or more motor driven limited
range POWERSTAT
®
Variable Transformers. Units
with a suffix, starting with a dash, at the end of the
model numbers are equipped with standard options.
Refer to the WHR model numbering system in the next
section for more details. See the enclosed rating charts
and unit nameplate for complete specifications.
Advantages of all WHR Series voltage regulators
include high efficiency (99% typical), high overload
capacity and low impedance. These voltage regulators
are insensitive to the magnitude and power factor of the
load, and have little to no effect on system power
factor. This means these regulators can be used with
any type load.
