 IMPROVEMENTS

 1 constructed to care for the future when the present supply from Bunk ! CT Hill, Waterbury, will be stepped up from 33,0O0 volts to 66,o00 volts. The present supply from over the mountain to the west is brought in on high tension wires to this city which carry 33,o0O volts A large gang of trouble-men are employed in ] daily tour of the ways over which these wires carry the current, in or- der to repair promptly any breaks which may occur and to insure con-
 stant nigh service to all places which
 the wires feed. This high current is carried on the big steel towers, which local people have so often seen, cross ing fields and highways from Water bury 10 this city and continuing on to Middletown where it supplies fur ther territory.
 Locally Black Rock sub-station is
 being rebuilt to care for much more work. Two 13,000 power circuits are being installed for service in this city. They are being reconstructed along private right of way on Trum- bull street, over Black Rock bridge,
 to railroad property, along which 1t runs through the main district feed ing the industrial plants of the city By installation {of additional cir cults snd by way of subway con- nectiohs on West Main street power will be brought to the new sub-sta- tion at Corbin Place, New Britain's own power distributing home. The other circuits run along the railroad property to Elm street where they will go underground and be connect
 ed with the corbin Place station.
 Tn Loop Circuit.
 Thus New Britain will rank with the. large industrial cities. of the country for beneficial and efficient service because of the fact that the installation. of these groups of cir cults has given the city what electri- cal mcn know as the ring or loop" circuit This comprises two circuits which run in opposite directions but have q common meeting place, the new Corb1n Place sub-station. Thus anything happens on the lines along l the railroad property, the system is ! Immediately cut out, and electricity
 is received for the city from the oth- CT half of the loop This means | of electricity If the trouble is local; 1T it. is in some place outside the city .,t night affect the whole loop
 or tn. whole city. The power. as already stated, that enters at Black Rock, is brought in at 33,0o0 volts This iz not used in the city, how ever. The nigh voltage is stepped down In two distinct classes. One voltage is stepped to 13,200 volts which is used for industrial needs in the city while 2,20e volts is normally
 supplied to the regular lighting sys- Item in the city. The 13,200 volts 1 carried by the new circuits along the
 railroad through the main industrial
 section of the city supplies such places
 as the Stanley Works, Fafnir Bear ing company. Landers Frary and Clark, and the American Hardware lcorporation, as well as other factor
 ies In New Britain. The 2,200 volt
 age, is supplied, to homes and other ! places which have the normal light ink power When anything happens
 to the higher tension wires. there is not as much danger to workmen as 4 in the lesser current troubles, in the l opinion of MT. Jourdan. This is due to the fact that automatic circuit l breakers operate quickly and more surely for the higher currents and 1 cause the wires affected to become dead. Thus handling the wires after they are down is not dangerous as I the current has automatically been shut off from them. Most of the ! trouble ensues from the smaller cur rent which workmen fear less and
 handle more often.
 l. -4, Better Service
 The service in the center of the city will be more efficient than ever, according to statement of the super intendent,s who says that they are en- 1 tirely. revising the layout of the sub- l way distributing lines which serve the 1 business center. New Cables, the latest l witches, and up-to-date electrical l devices will be installed in an effort l to give the city the best of service. In connection with this work, the com lpany is building with an eye to the l future. With installation of these new
 cables and devices, plans were made 1 for their enlargement and many con-
 nections which may have to be made | with the growth of the city and larger demands for current in the center of
 the city. As a result of this rebuilding,
 the city of New Britain has had to en-
 large the subways and manholes in a
 number of places. Some question If
 the enlargements has been raised by
