Manufacturing or power department.—This department operates the steam or water power generating stations which develop the electrical energy. Where small substations, which transform the energy received from the large stations, are required these may also be under the jurisdiction of the manufacturing department. It handles the maintenance and operation of boilers, steam engines, turbines, generators, rotary converters, switchboards, and all power “manufacturing” equipment.
In the steam division of the power department work about the station which requires no skill, such as handling of coal, removal of ashes, washing of boilers, and similar tasks, is performed by laborers. In this division are employed also water tenders and engineers.
In the electrical division operators and their assistants maintain and operate the electrical equipment in the station. This includes generators, motors, rotary converters, switchboard, and the like. Switchboards must often be quite elaborate. This is necessary to provide for the proper electrical interconnection between the various machines in the plant, and the outgoing lines which feed the substations and the customer’s premises. A principal duty of a station operator is to “tend” the switchboard, operating the switches and devices on it as may be necessary. In general the control of all the electrical apparatus in the station is effected from the switchboard, by which machines are started and stopped, and circuits cut in and out.
Switchboard operating in the power department.—The qualifications of a switchboard operator are that he be familiar with the use and operation of the different machines and electrical equipment in the station. Particularly he should be familiar with the switchboard. He should understand something of electrical theory. The requisite training is obtained often by men working up from the ranks, through experience in the station. However, such knowledge can be acquired much more quickly and readily if one has had a short course in electricity such as that which may be obtained at a Federal Board school. Ability to handle the more important duties of these positions must, however, be acquired by experience on the job. A disabled man who can hear, see, move about, and throw switches quickly may develop into a good station operator.
The work is not heavy, and it is indoor work. Sometimes the shifts are 12 hours, but the tendency is toward eight-hour shifts. Promotions are from assistant operator to operator, and then to chief operator. The salary for an operator will range from $80 to $125 per month. A man who is familiar with steam as well as with electrical equipment will be qualified for promotion to the responsible position of chief engineer.
PLAN No. 1205. LINE CONSTRUCTION OR DISTRIBUTION DEPARTMENT
This department builds the lines, either overhead or underground, which convey the electrical energy from the generating station to the substations and to the consumers. It also maintains the lines and for this work there may be a separate maintenance division of the construction department. The work is almost wholly out of doors. It involves the setting of poles, placing of cross arms, stringing of wire, building of underground-conduit systems and manholes, erection of switchboards, and installation of inside wiring. The labor is usually strenuous. However, some of the work, such as inspecting, planning, drafting, and supervision requires little physical effort. Men having minor disablements, particularly if they have had previous experience in construction work, should be able to qualify. In this, as in all other electrical branches, it will be found a paying proposition to take a short theoretical course before resuming practical work.
Construction departments usually work eight hours a day, although in some companies a nine-hour or even a ten-hour day is the rule. A construction inspector will receive a salary ranging from $90 to $125 per month, foreman from $100 to $175, and a draftsman from $60 to $150. An inspector, if he has sufficient experience and also the ability to handle men, can often become foreman. The work is very steady. If bad weather prevents outside operation, they are given indoor work.
PLAN No. 1206. METER DEPARTMENT
Installation, removal, testing, and repair of the meters which measure consumed electrical energy is the work of the meter department. After a meter has been installed in a building it should be tested periodically to insure its continued accuracy. These periodical tests are made on the customer’s premises. If the instrument is shown to be inaccurate it is replaced by one which is accurate, and is taken to the repair shop for overhauling. Thus the meter department does some of its work outside and some in the shop. In the larger companies the men who test the meters in the customer’s buildings ordinarily do nothing else. A different group of men repair and test the meters in the shop. With the smaller companies the same men or man may have to do both the inside and outside work.
