Previous Year Question

Industrial electrical installations often require power quality measures due to:
  1. Absence of motor-driven equipment
  2. Use of decorative lighting systems
  3. Low magnitude of connected load
  4. Presence of nonlinear loads and sensitive equipment

Correct answer: D

Explanation

Nonlinear loads can inject harmonics, while sensitive electronic equipment can be affected by voltage dips, distortion and transients. Industrial sites containing both therefore need power-quality monitoring and mitigation.

Step-by-step solution

Correct Answer

D — Presence of nonlinear loads and sensitive equipment

Explanation

Nonlinear loads can inject harmonics, while sensitive electronic equipment can be affected by voltage dips, distortion and transients. Industrial sites containing both therefore need power-quality monitoring and mitigation.
