Question

your final test voltage is 50kv ac. at what rate should you increase the voltage after 38 kv ac?
0.5 kv/second
1.0 kv/second
2.0 kv/second
5.0 kv/second
4 of 10 questions remaining

Explanation:

In electrical testing (related to Engineering, a subfield of Natural Science), when increasing voltage after a certain point (here, 38 kV AC towards 50 kV AC), the standard rate for voltage increase in such tests (like dielectric or insulation tests) after reaching a significant portion of the final voltage is typically 1.0 kV/second. The other options (2.5, 2.7, 5.0 kV/second) are either too fast (which can cause inaccurate or unsafe testing) or not the standard rate for this phase of voltage rise.

Answer:

B. 1.0 kV/second
