Figure 7.2: Joint Ownership Line Meeting Requiring Loss Compensation

A single meter cannot measure the losses in a transformer or transmission line 
directly. It can, however, include computational corrections to calculate the losses and 
add or subtract those losses to the energy flow measured at the meter location. This 
is the method used for loss compensation in the Nexus® 1500+ meter. Refer to 

Appendix A in this manual and Appendix B of the 

Communicator EXT

TM

 4.0 and Meter-

Manager EXT Software User Manual

 for detailed explanation and instructions for using 

the Transformer Line Loss Compensation feature of the Nexus® 1500+ meter.

The computational corrections used for transformer and transmission line loss com-
pensation are similar. In both cases, no-load losses and full-load losses are evaluated 
and a correction factor for each loss level is calculated. However, the calculation of the 
correction factors that must be programmed into the meter differ for the two different 
applications. For this reason, the two methodologies will be treated separately in this 
chapter.

In the Nexus® 1500+ meter, Loss Compensation is a technique that computationally 
accounts for active and reactive power losses. The meter calculations are based on 
the following formulae. These equations describe the amount of active (watts) and 
reactive (VARs) power lost due to both iron and copper effects (reflected to the sec-
ondary of the instrument transformers).
