We’re Working to Exceed Your Power Quality Needs
If you’re an SDG&E customer, you should not have to worry that your electricity doesn’t give you the power you need. Our Power Quality Team was created to ensure the electricity powering your facility meets our quality and reliability standards, and ensure your business experiences a minimum of interruptions that can interfere with equipment operations and data integrity.
The Power Quality Team provides testing, evaluation, technical analysis and reporting services at no additional cost to our customers. The team is made up of SDG&E engineers and technicians who provide technical expertise and practical solutions for a wide range of power quality concerns. The Power Quality Team provides:
Power quality site inspection
Electricity service monitoring
Reliability review and reporting
Report a Voltage Problem
Per California Public Utilities Commission Resolution E-4898 approval, with modifications, of request for modifications to Electric Rule 21 tariff to incorporate smart inverter phase 3 advanced functions in compliance with Decision 16-06-052, SDG&E is ordered to explain our voltage complaint process.
If an SDG&E customer suspects a voltage issue, the customer should call SDG&E’s Call Center to report the suspected voltage issue at 1-800-411-SDGE. SDG&E will dispatch an Electric Troubleshooter to begin the initial investigation and if possible, rectify the voltage complaint initiated by the customer. The Electric Troubleshooter may conduct the following steps in his investigation:
- Establish customer contact to determine what the nature of the voltage issue is, when the voltage issue occurs and whether the problem is intermittent or if it occurs during a specific time.
- Make a voltage check by measuring the voltage at the service entrance with the customer’s load connected and running to determine whether the problem may possibly be with the customer equipment or wiring.
- Conduct a wiring and connection inspection by checking for loose connections and for visual evidence of overheating.
- Measure the voltage and loading of the station and determine the size of the transformer feeding the customer, the number of customers on the station, and the distance of the customer from the station. The Electric Troubleshooter may also measure the voltage at adjacent stations to determine if the issue is localized on the secondary side or on the primary side and may also measure voltage at a nearby capacitor bank.
- Determine if further action is required and if the problem is intermittent or occurs at certain times, the Electric Troubleshooter may suggest further action be taken and request a follow up for corrective action or recommend the need for a recording monitoring device to be installed.
If further corrective action is required, the Electric Troubleshooter will follow up for corrective action to be taken by the Field Engineer who will analyze the data and determine the follow-up course of action. The Field Engineer who is handling the follow-up may conduct the following steps.
- Download the customer’s Smart Meter data if available.
- If a recording monitor is needed, the Field Engineer will coordinate with the customer to install the recording monitor at the service entrance for approximately one week. If customer has a PV system, the Field Engineer may request the customer to turn off their PV system for 24 hours to record the service without the effects of the customer’s PV system.
- Review the data to determine a solution to rectify the voltage problem.
- Coordinate with the customer at the completion of the solution recommended to remedy the voltage problem and close out the voltage complaint issue.
