The system is used to apply AC voltage on voltage transformer and measure its error. They system is metal enclosure type. The step-up transformer and standard instrument transformer are integrated in one modular.
Application
Thesystem is used to apply AC voltage on voltage transformer and measure itserror. They system is metal enclosure type. The step-up transformer andstandard instrument transformer are integrated in one modular.
Thesystem is designed for sorts of potential transformers such as capacitive PT,electronic PT, electromagnetic PT.
Features
l Easy transportation: thetotal height is less than 1.8mwhile transportation. It is able to go across bridges and tunnels.
l Easy operation: the systemcould be lifted or laid down with hydraulic pressure
l No need of connecting cables:since the exciter transformer, voltage regulator , reactor and standard voltagetransformer combine to one modular. The connecting cables between are avoided.
l Low noise: using high qualitycore, with special seismic reduction structure, the reactor brings very lownoise less than 60dB in operation.
l Good insulation performance:insulated by SF6, with relatively high safety factor. The system runs reliablyand safe.
