Advanced Lineworker Training (ALT)

Phase 1

3 Days: Phase 1 topics include distribution cover-up, personal protective grounding, regulators, capacitor safety, wood pole inspection, electric fundamentals for lineman, transformers information for lineman, transformer banking with demo models, transformer (paralleling), transformer troubleshooting. The class is an open discussion, and safety is always a part of every conversation.

Phase 2

3 Days: Substations and switchyards may seem complex and confusing to untrained personnel, but once they are reduced to the basic components — which this module does — they are much easier to understand. Participants learn the functions and safety requirements for working with each type of substation operating equipment, enabling the lineworker to identify problems that could occur within a substation on a trouble call. This session reviews transformers and circuit breaker drawings.

Phase 3

3 Days: When servicing transformer banks in both day-to-day and emergency situations, understanding transformer bank sequence is essential. This module teaches three-phase connections, current flow and troubleshooting within these connections. Voltage phasers are key to transformer bank construction, operation, troubleshooting and emergency transformer bank problem solving and lineworkers with an understanding of voltage phasers can more effectively analyze transformer bank problems. Participants will practice hands-on problem-solving techniques through study and analysis of miniature transformers.

Phase 4

3 Days: Lineworkers need to know how system protective devices operate in emergency situations, to protect equipment from damage, reduce customer outages and limit hazards to life and property. This module provides training on reclosers as well as fuses and sectionalizers. Proper voltage regulation is important to both customer satisfaction and economic operation of a utility system. This module will teach lineworkers how to properly isolate a voltage regulator and familiarize them with the operating principles and settings of voltage regulators.

Phase 5

Proper installation of underground (UD) systems is critical to keeping them operating as designed. With the many different types of components and accessories – and with manufacturers developing new products each day – it can be difficult for utilities to know the correct procedures for each component. When working with medium voltage insulated cable and UD systems, not following proper procedures can have serious consequences. This module provides a comprehensive review of UD systems in general, with an emphasis on the following: Verify, isolate, test and ground, Medium voltage cable construction & theory, Proper medium voltage cable preparation & handling and more .
