| description | The invention relates to a transformer substation universal insulation monitoring device comprising a host which is provided with a first direct current CT interface, a second direct current CT interface and a direct current bus interface. The first direct current CT interface and the second direct current CT interface are both used for being connected with a CT acquisition module or a digital direct current CT, and the CT acquisition module is connected with an analog direct current CT; the DC bus interface is used for connecting positive and negative DC buses, the host detects the voltage to ground of the positive and negative DC buses through the DC bus interface, calculates the insulation resistance to ground of the positive and negative buses according to the voltage to ground, and gives an alarm when the voltage to ground or the insulation resistance to ground is lower than a set alarm value. And automatically starting a branch routing inspection function.
