GE Consumer & Industrial Multilin GE Communicator EXT Appendix B: Transformer/Line Loss Compensation Calcn. Worksheets Transformer/Line Loss Compensation Calcn. Worksheets B.1 Introduction The Edison Electric Institute’s Handbook for Electricity Metering, Ninth Edition, defines Loss Compensation as: A means for correcting the reading of a meter when the metering point and point of service are physically separated, resulting in measurable losses including I2R losses in conductors and transformers and iron-core losses. These losses may be added to, or subtracted from, the meter registration. Loss compensation may be used in any instance where the physical location of the meter does not match the electrical location where change of ownership occurs. Most often this appears when meters are connected on the low voltage side of power transformers when the actual ownership change occurs on the high side of the transformer. This condition is shown pictorially in Figure B.1. FIGURE B–1: Low Voltage Metering Installation Requiring Loss Compensation Ownership Change GE COMMUNICATOR EXT - INSTRUCTION MANUAL B–1
