Agenda Title:

Council action is requested to issue a purchase order to Trench Limited in the amount of $111,080.00 for eight capacitive coupled voltage transformers for the Power & Light Department.

Council action to issue a purchase order.

When Eckles Road was upgraded there were capacitive coupled voltage transformers (CCVT’s) that were not included in the upgrade. One of these older CCVTs has recently failed. Because of this failure it has been decided, for the sake of reliability, to change all the CCVTs of the same vintage. CCVTs are used in line protection and metering. The Eckles Road sub is one of our few 161 kV subs and a primary source for our import power. Eckles Road feeds directly into the Sub A yard, which distributes at least half of our import energy. With the majority of the power serving the city being imported, failure at the Eckles Road substation must be avoided.


To further improve reliability and serviceability the same CCVT is used at all of the 161 kV subs. This is the CCVT from Trench. Because we have standardized on this CCVT we are using Trench as a sole source. Eight of these CCVTs are needed at a total cost of $111,080. This will come out of Engineering’s Miscellaneous Substations budget number 7020-1106-5406 FERC 1714.


Approval of the item authorizes the Procurement Manager is issue change orders up to 10% of the approved amount, providing that funds are available.
