Standard Voltages and Guidelines
Bandera Electric follows the range of service voltages
in use by the American National Standards Institute (ANSI) for Electric Power
Systems and Equipment
C84.1-1989. The term "service voltage" is defined as the point where BEC's
electrical system connects with that of a member.
- Desirable -- requires that occurrences of service
voltages outside range are infrequent
- Acceptable -- are occurrences outside desirable
range resulting from practical design or operating conditions that are limited
in extent, frequency and duration
For more details about our service voltages
contact the cooperative.

Higher voltages (at primary level) are also part of
BEC's nominal service voltages.
Contact the cooperative for information about primary
level voltages. |
