Online Training - Cable Fault Location For Testing of Underground Power Cable

DESCRIPTION This training program has been designed to thoroughly instruct personnel in state-of-the-art cable fault locating and cable testing methods. The course uses a combination of classroom lectures, demonstrations and hands-on field experiments to teach the trainee cable testing and cable fault locating. The course material has been selected to train the fault locator, cable tester or troubleman to produce results safely, faster and less expensively, with consistently reliable results. Utilities can realize substantial savings in cable replacement and manpower budgets with HDW’s expert cable fault locating and cable testing training and guidelines. TUJUAN The objective of this course is to train utility personnel, fault locators and testers in state-of-the-art cable fault locating and cable testing while keeping additional damage to the good cable system to a minimum. At the conclusion of this program, the trainees will:

• Be able to locate faults with minimum risk to good cable
• Be familiar with state-of-the-art cable fault locating and cable testing technique and equipment
• Be able to select the right tool to do the job right

SASARAN The course has been desgned to train troublemen, linemen, technicians, supervisors and engineers in state-of-the-art cable fault locating and cable testing with minimum risk to good cable. The instructors pay attention to the specific needs of all class attendees. MATERI PELATIHAN 1. Background 2. Introduction 3. Safety and Isolation of Supply 4.
