Document Type and Number:
WIPO Patent Application WO/2021/260874
Kind Code:
A1
Abstract:
A gas insulated transformer is provided which can estimate primary voltage with high precision. This transformer is provided with a core, a secondary winding (12) wound around the core, a primary winding (11) wound outside the outer periphery of the secondary winding and coaxially with the secondary winding, a high voltage shield (13) which covers the outer periphery of the primary winding, a low voltage shield (14) which is opposite to the high voltage shield, a ground terminal (23), and a capacitor (21) which is connected at one end to the low voltage shield and at the other end to the ground terminal.
