SYSTEM LOSS defined as an energy losses of an electric distribution system that are unaccounted for or the difference in the energy purchased and/or generated and the energy sold.
A. FACTORS OF SYSTEM LOSS
1. Technical Loss
- Inherent losses from electrical materials such as conductors, connectors and splices.
- Defective/broken insulators.
- Equipments such as substation and distribution transformers
- Power lines (primary and secondary distribution lines)
- Over extended power line that will cause low voltage
- Other
2. Non-Technical Loss
(is caused primarily by human errors)
- Inaccurate meter reading and/or billing
- Unread KWH meters
- Unbilled new connections
- Insufficient Right-Of-Way/Non-clearing of Power Lines
- KWH meter tampering
- Defective/In-accurate kwh meters
- Pilferage (RA 7832)
- 24-hours service of streetlights (only 12-hours billing)
- Etc.
3. Administrative Loss
- Electric energy used by distribution utility in the proper operation of the distribution system and;
- Unbilled electric energy that is used for community related activities such as:
a. Distribution substation
b. Offices of the DU
c. Warehouse and workshops of the DU
d. Community activities
e. Other essential loads of the DU
B. IMPACT ON HIGH SYSTEM LOSS
- High Billing Rates
- Revenue Loss
- Coop decategorization
- More customer’s complaints
Note: Please report any illegal connection to avoid system loss
C. SYSTEM LOSS REDUCTION MEASURES
-
- Clearing of Lines/Hataw Linis Linya
- Power system sanity check
- Rehabilitation and correction of lines
- Replacement of defective kwh meters and Broken Insulators
- Checks at hotspots area
- Strengthen KWH meter reading/billing monitoring system
- Massive Inspection – Sugpo Electricity Pilferage
- Massive Pole Metering
- Primary Metering of Big Load Connections
- Kislap Koryente
- Massive Disconnection of Illegal Street Light Connections
