Seminar Description Substations are classified using more than one criterion. For example, they are classified based on their primary voltage, secondary voltage, the breaking devices on the primary side of the transformer, the breaking devices used on the secondary of the transformer as well as its location i.e. outdoor, indoor or partially outside the building and the rest indoor. Irrelevant of any of these methods of classification, the basic functions of the major components in any substation are the same for switching/transforming type substations: the primary breaking device (circuit breaker, load break switch plus a fuse) or a disconnect switch with an upstream circuit breaker), the transformer, distribution or power type function of MVA power it delivers and voltage class (dry type for indoor installation vs. liquid filled for outdoor ones) and finally the secondary side breaking devices plus the protection and control devices and equipment. This seminar will allow attendees to improve their understanding of issues regarding the different types of substations found within an electrical power system, their components, properties and specifications. Topics to be covered:
Who Should Attend This seminar should be of interest to those in companies that are interested in or involved with electrical installations, mainly substations application, layout and designs, like electrical utilities, consulting engineering, users of electric power and other industrial and institutional organizations that are interested in the different types of substations, their components and characteristics. SESSION 2: THE BREAKING (SWITCHING) DEVICES Circuit breakers and switches are major components of any substations. Their reliable operation is paramount to isolate faults or de-energize circuits to perform maintenance on the downstream equipment. Circuit breakers as well as switches are classified according to their voltage class (the system voltage where they are installed) into low voltage (from 120 V to 1000 V), medium voltage (above 1 KV and up to 72 KV) and high voltage (above 72 KV). Such devices can be operated manually or through a motor that charges the closing springs. This seminar will allow attendees to improve their understanding of issues regarding switching devices, circuit breakers and disconnect switches as applied at the different voltage levels of a power system including their operating mechanisms. Topics to be covered:
Who Should Attend This seminar should be of interest to those in companies that are interested in or involved with specifying, applying, designing, testing of circuit breakers and switches, like electrical utilities, consulting engineering, users of electric power and other industrial and institutional organizations that are interested in safe and reliable operation of the switching equipment in a substation. Protection schemes in substations are always connected to the electrical power system. Under normal conditions, they are supposed to do nothing. Though under faulty ones they are supposed to respond (send a signal to trip the appropriate circuit breaker or breakers), based on the saved (programmed) logic, as soon as reasonably possible, to isolate the faulty portion of the circuit and indicate the function that caused the relay to operate (eg. short circuit, ground fault, differential, etc.) as well as the recorded value that caused the relay to operate as well as the any historic data saved ones. This seminar will allow attendees to improve their understanding of issues regarding protection of electrical power systems including the different substations found in such systems. Topics to be covered:
Who Should Attend This seminar should be of interest to those in companies that are interested in or involved with specifying, applying, setting, testing of the different types and designs of protective relays, like electrical utilities, consulting engineering, users of electric power and other industrial and institutional organizations that are interested in safe and reliable operation of the protective schemes of the power system. The components (eg. circuit breakers, relays, etc.) of a substation must be able to communicate with each other and with the SCADA system. An important issue that has to be evaluated in-depth to assure proper reporting, control & indication is the protocol of communication of the different components of the communication network. Protocols may be defined based on their functionality (what it can accomplish), for example: collection of binary (digital data) & analog data, collection, freezing & clearing of counters, control of binary (digital) outputs & analog outputs, reporting of binary & analog events (report by exception), time synchronization, time stamping events & file transfer. This seminar will allow attendees to improve their understanding of issues regarding the different protocols that are available for communication between the different devices in a substation.

Who Should Attend This seminar should be of interest to those in companies that are interested in or involved with specifying, applying communication networks within the different types of substations, like electrical utilities, consulting engineering, users of electric power and other industrial and institutional organizations that are interested in reliable and compatible operation of the communication network in the electrical power environment. SESSION 5: GROUNDING & BONDING When a live line (or conductor) touches noncurrent carrying parts of an installation, the latter ideally must maintain a zero potential i.e. the theoretical ground voltage. In reality, the ground voltage under such faulty conditions rises. The major electric assemblies, like switchgear, switchboards, motor control centers and distribution panels are provided with a neutral as well as a ground bus, both of which have to be connected to the system ground in order to provide for personnel safety and proper operation of protective devices. This seminar will allow attendees to improve their understanding of issues regarding ground resistivity, how it is measured what is the acceptable value and how this value can be reduced as well as how the neutral is grounded.

Instructor Hany A. A. Kheir, P.Eng. – Virtual Electrical Power Institute (VePi) Hany Kheir, P.Eng graduated in 1977 fom AinShams University in Cairo, Egypt. He is a member of Professional Engineers Ontario (PEO) since February 1983 and Association of Professional Engineers and Geoscientists of British Columbia (APEGBC) since February 2010. He worked for organizations like Lummus as Electromechanical Engineer, Brown Boveri, Square D, Siemens, ABB Asea Brown Boveri as well as Vaughan Hydro Electric Commission (a PUC) in the different capacities as Project Engineer, Engineering Supervisor, Planning Engineer through which he gained extensive experience in the design and application of electrical power distribution system components and equipment (in accordance with ANSI, IEEE, NEMA, UL & ASTM, IEC & ISO as well as CSA, UECC & OH). He was, also, involved in the preparation of studies on electrical power systems, industrial/distribution systems automation and smart grids. He served as a member on several IEC technical committees. Previous seminars, conference, courses were through PEO, IEEE, Electricity Forum & EPIC. Registered attendees unable to attend the event may designate a substitute, provided APEGBC receives written notification at least one business day prior to the event.
