Section 5: Electrical requirements
This section describes electrical power and electrical protection requirements associated with the
XR6/XR3 transmitter. This section includes the following topics:
• Electrical power
• Station reference ground - see page 5-4
Refer to the Nautel Site Protection Manual for information about requirements associated with lightning
protection.
Electrical power
The transmitter is preconfigured to operate from a 50/60 Hz, 3-phase (3-wire plus ground, Wye or
closed delta)or 1-phase (2-wire plus ground) ac power source. You select the number of phases and
specific voltage range when you order the transmitter.
Nominal voltage (minimum and maximum)
The primary winding of the main ac power transformer contains taps to accommodate voltages that
differ from the ideal voltage of the power source. These taps provide increments and are selected
during installation to provide the nominal voltage for the transmitter.
The high voltage transformer comes with the following standard taps:
CAUTION: Technical pre-commissioning activities described in this section
require technical decisions and the customization of electrical circuits. Do
not attempt to perform these activities unless you are a certified
electrician.
