PROTECT - Protection Fundamentals

Length: 4.5 Days

Overview

Energy from electrical power systems or lightning can pose safety hazards to your personnel, cause fires and facility damage and result in service outages. Newer electronic equipment is even more sensitive to electrical surges, presenting a greater likelihood of unsafe equipment degradation.

PROTECT promotes your understanding of electrical energy sources, including lightning, power contacts and induced voltage from ground return power current. The principles and practices surrounding bonding, grounding, protectors and surge arrestors are covered in detail, giving you the information you need to more effectively protect your telecommunications office, outside plant facilities and customer premises equipment.

Upon course completion, you will be tested to reinforce your knowledge and determine areas for further study. Successful completion of this test will earn TPI Trainers Certification.

Customization: PROTECT reflects current industry standards and can be customized and presented at your location to meet the unique needs of specific work groups, such as installation technicians and managers, facility maintenance technicians, network maintenance technicians and technical support engineers.
