16 LEU Response to IR-3 - 17 The existing transformers are either rated 2.4 kV primary or 3.33 kV primary. The new units - 18 are dual voltage on the primary side to enable utilization once the system is upgraded to - 19 15Kv, 7.2/2.4 kV p...

AI summary The document discusses the specifications of new transformers, noting that they are dual voltage on the primary side to accommodate future system upgrades to 15kV. The transformers have different primary and secondary voltage ratings.

23 Request IR-4: - 24 Please provide a list of equipment to be replaced and their replacement equipment, including the - 25 following: - 26 a) Category of equipment, such as pole-top transformer, current transformer, potential 27 transform...

AI summary The response to Request IR-4 provides a list of equipment to be replaced, including pole-top transformers, insulators, cutouts, and poles, along with approximate quantities and specifications.

19 LEU Response to IR-8 - 20 a) See attachment LEU Transformer Operating Procedures. - 21 b) The only maintenance completed on distribution transformers is once they are removed - 22 from service, they are tested by Stark Oil for PCB if th...

AI summary The LEU outlines its transformer maintenance procedures, noting that transformers are only tested for PCBs when removed from service and are older than 1982. Those that pass testing are returned to service, while others are disposed of.

11 LEU Response to IR-9 - 12 a) there are currently 5 feeders in the Lunenburg Electric Utility System, two are 5.88 kV - 13 phase to phase and three are 4.61 kV phase to phase. Both voltages are no longer - 14 standard distribution voltag...

AI summary The LEU responds to IR-9 and IR-10 regarding the Lunenburg Electric Utility System's voltage standards, planned substation construction, and PCB disposal procedures. The response outlines current system conditions, future plans, and disposal processes for transformers containing PCBs.

Distribution Transformer Storage/ Removal and Disposal Procedure This procedure outlines the steps required for the storage/removal and disposal of distribution transformers owned by the Town of Lunenburg (TOL).

AI summary The document outlines the procedure for the storage, removal, and disposal of distribution transformers owned by the Town of Lunenburg.

Existing Distribution Transformers in service Units that are removed from service are temporarily stored in the storage yard. Transformers that are not damaged or not leaking are stored in Starr St. until there is a load (approx.15 units)...

AI summary The document outlines the handling procedures for existing distribution transformers in service. Units removed from service are temporarily stored in a storage yard. Undamaged or non-leaking transformers are stored until a load of approximately 15 units is ready for pickup by Stark Oil, while damaged or leaking transformers are stored in plastic bags and immediately picked up by Stark Oil.

LEU Response to IR-11 LEU would like to confirm for the Board that the distribution transformers that potentially contain PCB's have not been oil sampled or tested while in service. They have been identified as potential PCB by visual insp...

AI summary The LEU confirms that transformers potentially containing PCBs have not been sampled or tested in service and are being removed to comply with regulations. They will be replaced with units compatible with the new 12 kV/15 kV system. The Town of Lunenburg's distribution system uses uncommon voltages, leading to potential equipment sourcing and replacement issues.

LEU Response to IR-15 15 KV is the voltage class of the new substation on the secondary. The 12 kV is the operating voltage. So, the 12 kV equipment will operate on the 15 kV substation.

AI summary The LEU explains that the 12 kV equipment will operate on a 15 kV substation, clarifying the voltage class and operating voltage of the new substation.

Request IR-15: In the application on page 2, LEU stated that "By upgrading these existing locations, it also prepares these locations for conversion to 12 kV." In response to IR-9, LEU also stated that it has planned a new 15 kV substation...

AI summary The LEU has stated that upgrading existing locations prepares them for conversion to a 12 kV system and has planned a new 15 kV substation. The relationship between these two initiatives is requested for clarification.
