Field Troubleshooting
The most likely field troubleshooting scenario is a failure to display. If the
Communication icon is not displaying, ensure that the TWACS-enabled
kV2c meter is receiving the appropriate power according to its specific form and
voltage (refer to Table 2.8 on page 30). You may use a Portable RCE Test Unit
(PRTU) and the PRTU Technical Manual for further testing or return the meter to
the Meter Shop for further diagnostics.
WARNING: Wear all safety equipment according to your utility rules before
opening the meter base: hard hats, safety face shield, fire retardant clothing,
high voltage rated gloves, safety rated shoes.
WARNING: Any work on or near energized meters, meter sockets, or other
metering equipment can present a danger of electrical shock. Such shock
could cause serious injury or death.
Complete the following steps if you determine a field visit is necessary. You can
end the procedure at any step and correct the problem when a cause of failure is
determined.
1. Once on site, verify the correct TWACS serial number is installed at the
site.
2. Determine if the meter is operational by performing a voltage check,
verifying the meter is the correct form and class for the application, and
making sure the service transformer is at least a 3 KVA transformer or
greater.
3. Determine if the meter is disconnected at the service transformer or booted
on the line side of the meter base.
4. Remove the meter and check for loose connections in the meter base or any
other type of defect that may prevent the meter from communicating
through TWACS power line communication.
