1. MJL.C
lectured notes for
SUBSTATION DESIGN COURSE for EE 5-2 and EE 5-3
STUDY, DESIGN ,INSTALLATION, CONSTRUCTION AND TEST METHOD OF
SUBSTATION EQUIPMENT INCLUDING PROTECTIVE RELAYING AND SHORT
CIRCUIT ANALYSIS.
COURSE OBJECTIVE :
TO GIVE STUDENTS OF ELECTRICAL ENGINEERING A GENERAL PATTERN AND
PRACTICAL METHOD ON HOW TO DESIGN,INSTALL AND TEST METHOD OF
SUBSTATION EQUIPMENT OF WHICH SUCH INFORMATION AND WORKSHOP
WILL HELP THEM IN THEIR PROFESSIONAL PRACTICE AFTER GRADUATION.
PRE-REQUISITE :
• ELECTRICAL EQUIPMENT
• AC CIRCUITS

2. 1.0 DEFINITION OF SUBSTATION…………………. PRIMARY SUBSTATION
RECEIVED POWER GENERATED BY A POWER STATION RANGE FROM 1kV TO
26kV AND IS FED TO TRANSFORMER THAT STEP THE VOLTAGE UP TO HIGHER
VALUES MORE SUITABLE FOR TRANSMISSION.
SUBSTATION CONTAIN POWER TRANSFORMER AND VOLTAGE REGULATING
APPARATUS REQUIRED FOR CONVERTING THE HIGH INCOMING SUB-
TRANSMISSION VOLTAGE TO LOWER PRIMARY SYSTEM VOLTAGES AND
MAINTAIN THEM WITHIN SPECIFIC VOLTAGE
