What is DC current injection (from the answer given in the above question)

Question

Accepted Answer

DC current injection is the process of introducing direct current into a circuit or system.

DC current injection is commonly used in various applications such as fault location, impedance testing, and ground resistance measurement.
It involves injecting a known amount of DC current into the circuit or system under test.
DC current injection can help identify faults, measure resistance, and assess the performance of electrical components.
For example, in fault location, DC current injection is used to determine the location of a fault in an underground cable by measuring the voltage drop along the cable.
In impedance testing, DC current injection is used to measure the impedance of a circuit by analyzing the voltage and current response.
DC current injection is also utilized in ground resistance measurement to assess the effectiveness of grounding systems.
