This is for generating the voltage and current necessary to conduct confirmation tests of the main circuit and VCT circuit after construction work at the power transformation station has been completed.

After the construction of the substation has been completed, it is necessary to conduct confirmation tests of the main circuit and VCT circuit to ensure that the work has been carried out properly. This device applies test voltage to the main circuit of the substation and is used for comprehensive confirmation tests of the phase detection of the main circuit and the secondary circuit of the VCT. 【Features】 ■ Test voltage can be selected via a push-button switch ■ Built-in voltage, current, and phase meters for labor-saving testing ■ Supports testing from both the primary and secondary sides of the main transformer ■ The resistance box is integrated into the lid of the main unit, separating during use and integrating during storage.
