The world's most powerful transformer bushing - ABB GroupABB has successfully type-tested the world's most powerful direct current (DC) transformer bushing developed for the ultra-high voltage direct current (UHVDC) transmission link project. This is an important milestone in the development of the longest, most powerful and highest capacity power transmission links in the world, being driven by China.
Switchgear and protection lecture 1 - SlideShare· A switchgear or electrical switchgear is a generic term which includes all the switching devices associated with mainly power system protection. It also includes all devices associated with control, metering and regulating of electrical power system. Assembly of such devices in a logical manner forms a switchgear.
Current Transformer (CT) Testers - ATEC current transformer tester identifies potentially disastrous current transformer faults, preventing the primary current from overwhelming insulation and in effect causing windings to short circuit. With a CT tester, an engineer can construct a comprehensive testing and maintenance plan to address faults before failures occur and expenses ensue.
Gas-Insulated Substations - GIS2020-11-17 · Superior Dielectric Gas. A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation.The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures.

Leak Transformer Parameters2008-2-11 · Notes from Leak Amplifier Owners: 1) Stereo 20 power transformers appear to have been revised during the production run. Early models had 300-0-300 volt HT secondaries, but this was revised to 280-0-280 V, possibly from a propensity for this transformer to overheat. The Leak circuits do not document this change. Comments from owners are welcome.
