Final answer:
The given statement "During a transformer removal procedure, the transformer should be completely isolated from all sources of voltage on both the primary side and the secondaryside before the ground lead is disconnected" is true. Isolation transformers provide safety by preventing a complete circuit and reducing the risk of electric shock.
Step-by-step explanation:
The statement is true: During a transformer removal procedure, the transformer should be completely isolated from all sources of voltage on both the primary side and the secondary side before the ground lead is disconnected.
This is a critical safety measure to ensure that there is no current flowing through the transformer which could cause electric shock or other hazards when disconnecting it.
Isolation transformers are an important safety device, designed to put a high resistance between the original voltage source and the device being used, which prevents a complete circuit between them and thus reduces the risk of electric shock.
For example, if a person touches only one of the transformer's output wires, and neither wire is grounded, the resistance is so high that current flowing through the person would be negligible.
Therefore, it is essential to follow safety procedures meticulously when removing a transformer to avoid electric shock and ensure electrical safety.
