Verified 2026-10-29 Confidence: High

Bushing Power Factor and Capacitance is specified for medium-voltage and high-voltage oil circuit breakers in maintenance testing at clause 7.6.2.B.9 of ANSI/NETA MTS-2023. The clause calls for power-factor or dissipation-factor tests on each bushing that has a power-factor or capacitance tap, and a hot-collar test where there is none.

Value: medium-voltage and high-voltage oil circuit breakers
