Ontario Sessional Papers, 1920, . ampere bushing type current transformers were purchased for use on ?Jl, CI and • C2 lines, and two Canadian Westinghouse lOO-ampcre, o\aitank reactance oil circuit-breakers with 400-ampere current transformers originallyinstalled in Niagara Transformer Station, were transferred to Dundas Trans-former Station, for use on the Bl and B2 lines. Plans have been prepn:showing the necessarj changes required to instal these breakers, and tlie instlation work, which is now being done by the Commissions Construction Depart-ment, will be completed about the last of December. 1919. The old oil circuit-breakers, as they are removed from service, are being shipped to the CanadianWestinghouse Companys factory to be rebuilt and reinforced to increase theircapacity. Low-Tension Equipment As the flat choke coils on two 13,200-volt Hamilton feeders were found tobe too light to carry the current, new spiral choke coils of heavier capacitv wereobtained and installed on these feeders in ^farcb, 1919. I. 1920 HYDRO-ELECTRIC POWER COMMISSION 181 As it was desired to obtain direct records of the total load in this station,plans have been prepared and instructions issued to parallel the 13,200-volt currenttransformers of each transformer bank on two 10-5/5-ampere current transformersfrom which leads are taken through a Westinghouse graphic recording meter and aWestinghouse recording, reactive volt-ampere meter to give the total load. West-inghouse type C polyphase watthour meters are also being installed on the leadsof each transformer bank. This work is being done by the Commissions OperatingDepartment, and is expected to be completed in November, 1919. As it was considered advisable, due to the importance of this station, to havebetter relay protection on the 13,200-volt feeders, new Condit type A inversedefinite time-limit relays were purchased and installed on feeders in April,1919, replacing the old Canadian Westinghouse type B relays,
