MV overhead line, Work on distance (Hot stick working) up to 36 kV

Theoretical training, MV overhead line, Work on distance (Hot stick working) up to 36 kV:

Seminar requirements:

• Electrically skilled person with sufficiently knowledge of work under absence of voltage, health viewpoint and personal suited
• proof of first-aid training
• evidence of introduction for elevating work platforms

Duration: 2 to 5 days

• Basics of occupational safety
• Calculating of forces, breaking load etc. moving of rope under considering of forces
• Rules on live working, labor protection law, IEC, EN…
• Work methods to work near live installation and production inputs
• Live working
• Work instruction, permission for live working, safety regulations in live working
• Principles for preparation, carrying-out, completion and termination of live working
• Common working method while live working, work on distance
• Cooperation authorized skilled electrical technicians who give instructions, system manager, network control station
• Supervisor on the ground
• Minimum approach distance (MAD)
• Handling of equipment in different types of pylons
• Development of work instruction for live working in different types of pylons
• If relevant: management structure of company
• Application, cleaning, maintenance and inspection of equipment
• Written exam

Passing the test will be precondition for participating in practical training which can coordinated individually.

Example:

Theoretical training in mounting and dismantling of bird protection caps up to 36 kV

Duration: 2 days

Duration: 3 to 15 days (including observing after training in medium-voltage grid)

• Feasibility analysis for the respective technology at the existing type of pylon
• Development of work instruction considering type of pylon
• Calculation of forces of working pylon
• Preparation live working medium voltage (equipment, humidity, construction, placing an order, system manager/ network control station…)
• Execution of live working
• Termination / completion of live working
• Cleaning and maintenance of the equipment
• Handling of equipment considering minimum approach distances
• Working with ladders or non-insulated elevating work platform
• The practical part will be done de-energized and by real Live Working
• practical test
• evaluation

Examples:

• Installation of bird protection (caps)
• Mounting of short-circuit indicators
• Covering at tower stations, refurbishments of concrete pylons
• Change of tension insulator
• Change of suspension insulator
• Mounting of electrical disconnecting points
• Opening and closing of current loops
• Repair of line damages

Example:

Pratical training: Duration 3 days

• Mounting and removing of bird protection caps
• Mounting and removing of BSD perch rejectors
• Mounting and removing of BSD covers for strain poles
• Mounting and removing of short-circuit indicators
• with ladders or ordinary elevation platform up to 36 kV
