Resistor Structure and a Voltage Divider Arrangement

A voltage divider arrangement for electrical power systems for transformation of voltage, the voltage divider arrangement comprising:

• a first resistor structure having a first resistance, and a second resistor structure having a second resistance and connected in series with the first resistor structure, wherein the first resistance is different than the second resistance;
• wherein at least one of the first and the second resistor structure comprises:
• an electrically insulating substrate;
• at least one electrically conductive terminal directly or indirectly provided on the electrically insulating substrate;
• at least one resistive path comprising at least one resistive trace directly or indirectly provided on the electrically insulating substrate and directly or indirectly joined to the electrically conductive terminal, wherein the resistive trace has a thickness in a thickness direction facing away from the electrically insulating substrate;
• wherein at least one insulator element is applied directly or indirectly and at least partially on the electrically insulating substrate, wherein the at least one insulator element has a thickness in the thickness direction facing away from the electrically insulating substrate;
• wherein at least a part of the insulator element and a part of the resistive path are arranged at least partially adjacent to each other;
• wherein (a) when the resistive trace is substantially free of a coating of a thickness between 1 μm and 200 μm, or is free of any coating, the thickness of the at least one insulator element is at least 30% of the thickness of the resistive trace;
• and/or
• wherein (b) when the resistive trace is substantially covered by an insulating coating having a thickness between 1 μm and 200 μm, a total thickness of the at least one insulator element and of the insulating coating exceeds the thickness of the insulating coating on the resistive trace optionally by at least 30%.
