WebOct 31, 2024 · If the test voltage is 3000, then the test current would be 3000/250 x 0.5 or 6 mA. If the test is dc, then the current during the test is a function of the insulation resistance of the system, including the insulation resistance of the stray capacitance and the Y capacitors. The dc current is typically in the tens of microamps. Conclusions WebGTC-9040 AC Ground Bond Tester is a specialized product, used to test and evaluate the connection of the shell components to the grounding part of any electrical equipment (Ground bond test). The device is capable of generating test signals with currents up to 40A AC. The smallest resistance value GTC-9040 can be measured is 1mΩ.
