SAN DIEGO GAS and ELECTRIC COMPANY

CORRECTIVE MAINTENANCE PROGRAM

REPORT FOR

2000

Prepared By: Frank Marsman (6/26/2001)

INTRODUCTION

The Corrective Maintenance Program (CMP) is managed through San Diego Gas and Electric's (SDG&E) Distribution Management and Strategies Department. By coordinating with the Construction & Operations (C&O) Centers, General Foremen, Inspectors and other personnel, the inspections required by the CMP are performed and follow-up work to correct deficiencies is completed. Corrective action, for items other than those rated as needing immediate attention, is handled on a 12 months cycle.

A listing of inspection schedules is included as Attachment "A" in accordance with General Order 165.

The underground switch inspections have been divided between above ground (pad mounted) and subsurface in accordance with GO 165 requirements.

The individual segments for 2000 are as follows:

Patrols

Detailed overhead visual inspection

A walking program of visual inspection of overhead facilities and primarily pole mounted equipment.

Detailed underground external inspection (Dead Front)

Detailed underground internal inspection (Live Front)

Underground oil and gas switch inspection

Intrusive wood pole reinforcement inspection

2000 ANNUAL REPORT

PATROLS

Following is the percentage of SDG&E's system in urban and rural areas that was patrolled during 2000:

· Urban Area

· Rural Area

Following are the number of problems identified by overhead and underground patrols:

OVERHEAD PATROL

UNDERGROUND PATROL

DETAILED INSPECTIONS

OVERHEAD

· Detailed inspections of all poles in the overhead system will be performed on a 5-year cycle. Approximately 20% of SDG&E's total pole population will be inspected annually. Small variations in inspected percentages may occur yearly, but 100% will be completed every 5 years. Pole mounted equipment and conductors supported by the poles are inspected at the same time. As with the poles the annual percentage may vary but 100% will be completed every 5 years. This is the 3rd year of the cycle.

· The detailed overhead inspection requires that each pole position be visited and the pole and the equipment supported by the pole be carefully examined visually for conformance to CPUC General Order 95 requirements. By systematically inspecting all poles and the equipment they support, required equipment inspections will be completed within the time frames prescribed by General Order 165.

· Corrective action, for items other than those needing immediate attention, is handled on a 12 months cycle. Equipment and spans of conductor needing corrective action are managed by the structure that supports them.

UNDERGROUND (PAD MOUNTED) INSPECTIONS

The underground pad mounted inspection consists of two separate inspection types:

· Dead Front Equipment

· Live Front Equipment

Dead Front Equipment

Detailed inspections of all dead front, pad-mounted equipment, in the underground system is performed on a 5-year cycle. Approximately 20% of SDG&E's total pad mounted dead front equipment is inspected annually. Small variations in inspected percentages may occur yearly, but 100% will be completed every 5 years. This is the 3rd year of the cycle. This inspection has been altered to include an internal inspection segment.

A detailed inspection of dead front, pad mounted equipment requires that each dead front, pad mounted piece of equipment be visited and the piece of equipment be opened and carefully examined externally and internally, by visual methods, for conformance to CPUC General Order 128 requirements.

Live Front Equipment

· Detailed inspections of all live front, pad mounted equipment, in the underground system will be performed on a 5-year cycle. Approximately 20% of SDG&E's total pad mounted live front equipment will be inspected annually. Small variations in inspected percentages may occur yearly, but 100% will be completed every 5 years. This is the 3rd year of the cycle.

· A detailed inspection of live front, pad mounted, equipment requires that each live front, pad mounted, piece of equipment be visited and the equipment be opened and carefully examined externally and internally, by visual methods, for conformance to CPUC General Order 128 requirements.

UNDERGROUND (SUBSURFACE) INSPECTIONS

· Detailed inspections of all underground subsurface transformers and regulators/capacitors, in the subsurface underground system will be performed on a 3-year cycle. Approximately 33% of SDG&E's total population of these pieces of equipment will be inspected annually. Small variations in inspected percentages may occur yearly, but 100% will be completed every 3 years. This is the 3rd year of the cycle. A detailed inspection of underground subsurface equipment requires that each subsurface enclosure be visited and opened so that the equipment within can be carefully examined visually for conformance to CPUC General Order 128 requirements.

UNDERGROUND SWITCH (SUBSURFACE) INSPECTIONS

· Detailed inspections of all subsurface switches in the underground system are performed on a 3-year cycle. Approximately 33% of SDG&E's total population of these pieces of equipment are inspected annually. Small variations in inspected percentages may occur yearly, but 100% will be completed every 3 years. This is the 3rd year of the cycle.

· A detailed inspection of underground switches requires that each equipment location, pad mount or subsurface enclosure be visited and opened so that the equipment within can be carefully examined visually for conformance to CPUC General Order 128 requirements. In addition, oil filled switches will have the oil sampled and processed by the lab for conformance with SDG&E standards.

INTRUSIVE POLE INSPECTION

WOOD POLE

· Intrusive inspections of all poles in the overhead system are performed in conformance with CPUC General Order 165 requirements. Approximately 10% of SDG&E's poles over 15 years of age, that have not had a previous intrusive inspection, will be inspected annually, creating a 10 year inspection cycle. This is the 3rd year of the cycle. SDG&E poles that are older than 15 years and have had a previous intrusive inspection will be inspected on a 20-year cycle with approximately 5% of these poles being inspected annually. This is the 3rd year of the cycle.

· Small variations in inspected percentages may occur yearly, but 100% will be completed in conformance with CPUC General Order 165 requirements.

· The intrusive pole testing program at SDG&E is a centralized program that systematically addresses all SDG&E poles on a system wide basis and not on a district by district process. Program direction and records are handled on a centralized basis.

· Intrusive testing of wood poles is normally accomplished by excavating about the pole base and/or a sound and bore of the pole about the groundline area for conformance to CPUC General Order 95 requirements.

10 Year Inspection Cycle

· If this answer is not 100% explain and provide date corrective actions to be completed by:

20-Year Inspection Cycle - SDG&E is inspecting all wood poles on a 10-year cycle at this time.
