[0002] A voltage transformer, like a transformer, is an instrument used to transform voltage. However, a transformer's purpose in transforming voltage is to facilitate the transmission of electrical energy, so its capacity is large and is generally measured in kilovolt-amperes or megavolt-amperes. A voltage transformer, on the other hand, transforms voltage primarily to power measuring instruments and relay protection devices, to measure line voltage, power, and energy, or to protect valuable equipment, motors, and transformers in the event of a line fault. Therefore, the capacity of a voltage transformer is very small, typically only a few volt-amperes or tens of volt-amperes, with a maximum capacity of no more than one kilovolt-ampere.

[0003] Application No. 201310498795.9 discloses a voltage transformer comprising a seamless toroidal core, a secondary winding, an insulation layer, a shielding layer, an epoxy resin mixed adhesive layer, a coil bobbin, and a primary winding, which are sequentially wrapped. The primary and secondary windings are wound by a CNC winding machine on the seamless toroidal core, a coil bobbin is placed over the entire secondary winding, insulation layer, shielding layer, and epoxy resin mixed adhesive layer, and a primary winding is wound on the coil bobbin using a CNC parallel winding machine. The primary winding is rectangular or pagoda-shaped, with the pagoda shape having two or three levels. The seamless toroidal core is a hollow cylindrical core with a ring-shaped cross-section, formed by winding a cold-rolled grain-oriented silicon steel strip.

Errors may exist in the size of the voltage transformers, which may result in the inability to install the voltage transformers or poor contact of the voltage transformers.
