To find the voltage between the "stinger" leg of a delta transformer and ground, we need to understand the characteristics of a delta transformer.
A delta transformer is a type of transformer configuration used in electrical engineering, typically for commercial and industrial power distribution. In a delta transformer, the transformer windings are connected in a closed loop, forming a triangle (or delta) shape.
In this configuration:
1. There are three legs (phases), each connected to a different corner of the delta triangle.
2. One of these legs is often referred to as the "stinger" leg or "high leg."
The voltage between the "stinger" leg (also known as the high leg) and ground is a fixed value based on electrical engineering standards.
Given the options:
- A. 120 V.
- B. 240 V.
- C. 277 V.
- D. 208 V.
The correct answer is D. 208 V.
This is because, in a delta transformer configuration, the high leg (stinger leg) to ground voltage is standardized to be 208 volts.
