Frequently Asked Questions (FAQ)
Q: How does the instrument perform a capacity test without external power?
A: The instrument provides a built-in three-phase 50Hz AC test power (0～10V, 0～10A). Simply connect the wiring and ensure the non-powered side is short-circuited.
Q: What if the test voltage or current exceeds the instrument range?
A: Connect external PT (voltage transformer) or CT (current transformer). Input the PT/CT ratio in the parameter settings e.g., 10kV/0.1kV=100. The instrument automatically calculates the actual values.
