SUMMARY
The term ZPB in power systems stands for "Zero Power Bus," which is identified as a reference bus for voltage measurements. This definition is confirmed in the power systems textbook referenced, specifically on page 10, section 5.3 of the document available at Made Easy. The discussion highlights the importance of the zero sequence impedance in relation to balanced zero sequence returns through the neutral, establishing the ZPB as a critical concept for understanding voltage measurement in power systems.
PREREQUISITES- Understanding of zero sequence impedance in power systems
- Familiarity with voltage measurement techniques in electrical engineering
- Knowledge of reference buses in power system analysis
- Basic concepts of balanced and unbalanced loads in electrical circuits
- Research the role of zero sequence impedance in fault analysis
- Learn about the significance of reference buses in power system stability
- Explore voltage measurement techniques in three-phase systems
- Study the implications of balanced versus unbalanced loads in power distribution
Electrical engineers, power system analysts, and students studying power systems will benefit from this discussion, particularly those interested in voltage measurement and zero sequence analysis.

I'm guessing here, but how about "Zero Potential Branch", i.e the branch that the other branches are referred to for a voltage measurement; the "local ground" for measurements.
Paging @jim hardy. Jim is the local power guy here and can likely come up with a knowledgeable answer.

Indeed. I never had a course in power system analysis so what little i know came about mostly by osmosis. The abbreviation was not familiar to me.
Thanks @Baarken . That makes sense . Balanced Zero sequence returns through neutral so it's intuitive to declare that as reference. "Today i learned.."
Thanks all.
