Automated switchboards. A decade later, more than 30% were automated, according to a 2019 article by the Federal Reserve Bank of Richmond.The growth of automatic switchboards led to the direct-dial telephone in the 1920s. (The “0” for operator appeared with dial phones, said Lauer from the University of New Hampshire. On the new Bell dials, “Operator” was printed in the “0” position. The use of “411” also emerged with the dial era. “0” became universal for operator assistance and “411” was the number for directory assistance. In later years, if you dialed “0 and asked for directory assistance, the operator would transfer you over to “411.”)But electronic switchboards and direct dialing were phased in gradually and did not eliminate the need for human operators.Automatic switchboards were mainly used for local telephone calls. For decades after the introduction of direct dialing, operators still handled long-distance calls, toll calls, and calls to the police and fire department. This meant that operator jobs continued to rise until around the 1970s.Directory assistance was also mostly free for customers until the 1970s, when AT&T began charging customers to curb the “misuse” of the service and shift the high costs of employing operators and handling time-consuming queries for information.“Some people just simply don’t want to bother to look the number up themselves,” AT&T’s chairman complained in 1974.The breakup of AT&T in the 1980s and the deregulation of the telecommunications industry altered operator and directory services. Phone companies began to cut their ranks of operators, automate services. How do you create a switchboard in Microsoft Access? Type the name of the new switchboard and click OK.

Layout but usually on a smaller scale.All the same precautions have to be taken with respect to safety, access arrangements, protection, etc., as with main substations. 4.1 Outdoor substationsWhere all the equipment is mounted in the open the enclosures must be of weatherproof design (i.e. suitable for all the relevant external influences). This generally relates to MV substations.Transformers are automatically suitable for outdoor mounting, but if liquid-filled designs are employed they need to be provided with drainage facilities, as discussed later.Ring-main units are used both indoors and outdoors and designs are available that are suitable for this. Distribution cabinets are needed for the LV distribution feeder cables.Railings or anti-vandal fencing are provided to enclose the equipment to form the substation (Figure 5).Figure 5 – Typical outdoor substation layout There are also packaged MV/LV substations that utilize standard indoor equipment mounted inside a weatherproof enclosure. The transformer may be outside the housing which contains the MV and LV switchboards, separated by a corridor.Room for rear access to the switchboards may have to be provided.A claimed advantage for this type of substation is that it allows the foundation to be prepared well in advance and is ready to accept the assembled equipment direct from the manufacturer. It is not so popular today because of economic considerations, but has the advantage that maintenance on the switchgear is possible in all weathers.An economic arrangement of outdoor substations is the so-called integrated design which has switchgear mounted on the transformer cable boxes, permitting a naturally cooled transformer to be employed (Figure 6).Figure 6 – Typical multi-transformer substation4.2 Outdoor/indoor substationsThe more conventional arrangement of MV substations is to have outdoor transformers with indoor 11kV and 400V switchboards.Transformers are housed in an annexe to the switchroom and there may be separate chambers for 11kV and 400V switchboards, battery and charger and controls.It is often convenient to have a separate control room for installations which include more than one substation, standby generation, combined heat and power systems and process plant requiring sequencing and interlocks.This arrangement is preferable for town or urban substations because of the convenience of using standard indoor switchgear rather than the more expensive weatherproof designs. The difference in cost between indoor and outdoor transformers is not great, and because of the need to provide adequate ventilation the trend is to install them outside with protection against vandalism.A common practice for multi-transformer substations is to have weatherproof chambers for the MV and LV switchgear and metering and to mount the transformers in open pens as shown in Figure 7.Figure 7 – Cabling of substationWhere the MV switchgear is under different operational management from the LV side, the more conventional design of substation is probably the best.Comments

2025-04-10Fuel refit would have not been possible due to space limitations.”Prior to the refit, the ship was equipped with four main engines which were used for main propulsion and could supply via two shaft generators electric powers for the bow thrusters during maneuvering. All other electric load was supplied via three auxiliary engines. Propulsion was completed via two variable pitch propellers where each was driven by two main engines via a double in/single out reduction gear. All electric load was distributed via a 6.6kV AC main switchboard from which the two bow thrusters and the three air condition chiller units were directly fed. All other ship electrical consumers were supplied via 440V and 230V switchboards. The two bow thrusters were fixed speed variable pitch thrusters.“After the refit, the ship now has four main engines which have fixed coupled generators which produce 780V AC,” said Mass. “On the other side of the engines, they are connected via a clutch to two double in/single out gearboxes which drive the two variable pitch propellers. There are no more auxiliary engines installed. The electric load is now distributed via a 1000V DC switchboard which directly supplies variable frequency to the bow thrusters and chillers. The rest of the ships consumers is still supplied via the original 440V and 230V switchboards. The bow thrusters are now fixed pitch variable speed.”In addition, the ship has been refit with a 6.6kV shore connection which can, due to the DC main switchboard, be operated at 50 or 60Hz.“With the new setup we are achieving significantly more efficient and environmentally friendly ship operations in compliance with IMO Tier III regulations: less fuel consumption (10 to 15% expected), less NOx emissions (approx. 90%), optimized engine layout, more efficient electrical design (DC main switchboard), shore power system, and a low-friction hull coating,” said Mass.Engine room showing two of the four new main engines and the engine crew of the “Amera” (Tim Mass, front right).Copyright BSM CruiseMeeting Challenges Head OnAnyone that has engaged in an extensive ship refit project knows that challenges abound, particularly with the integration of extensive new machinery and
