3.3 Enhancing Staff Competence

Technical skills of relevant personnel directly impact the operation, maintenance, and fault diagnosis of RMUs da transformer substations. First, enterprises must place greater emphasis on technical personnel. Social media should increase positive coverage of staff to improve their social status. Companies must design training programs for maintenance personnel to help them enhance their skills and implement incentive and disciplinary measures to boost work efficiency. Maintenance personnel need to improve their capabilities through various methods. Conduct comprehensive and targeted training for employees, covering technical standards, management standards, and work standards, retrain employees according to professional and required training plans to enhance their enthusiasm for participation. Incorporate training into the performance management system, evaluate each training course and participant, and use the results as a basis for company rewards and penalties.

3.4 Developing Emergency Plans

Companies must prepare emergency plans in advance to ensure the smooth operation of RMUs da transformer substations. First, relevant personnel must promptly establish emergency measures. If equipment fails, maintenance personnel must rush to the site for inspection. If the fault cannot be repaired immediately, the emergency plan should be activated promptly. The relevant department should immediately notify other personnel to start backup equipment to prevent the fault from escalating. To avoid recurrence, employees should promptly analyze the problem and develop effective solutions.

4. ConclusionIn

summary, although RMUs da transformer substations have many advantages in actual operation, the existing problems cannot be ignored. We should adopt scientifically sound solutions to promptly address issues arising during operation to ensure the normal functioning of the distribution network.
