Introduction to the Electric System

Typical Equipment Recloser Capacitor Overhead Service Transformer Automatically senses a fault and isolates the problem area. Can be remotely controlled with additional equipment. Capacitor Provides support for electric motor loads. Boosts voltage by a fixed amount. Overhead Service Transformer Reduces voltage to a level which can be used in a typical home or business. Voltage Regulator Automatically adjusts voltage to maintain a programmed level.

Basic Supervisory Control and Data Acquisition (SCADA) Human Machine Interface allows the operator to remotely monitor and control devices Communication methods include radio, telephone, microwave, and others Remote Terminal Unit gathers information from and controls Intelligent Electrical Devices

Distribution Management System (DMS)

I added this slide only to take the opportunity to point out that whatever GM systems we put in place they need to take into account the wide disparity when it comes to geography, load densities, metering equipment deployed, system design, overhead vs. underground, DG saturation, etc.
