Electrical System

903 K Electrical DistributionElectrical power enters the complex from two Incomer Feeders at 66kV that enters the T&TEC switch yard. These electrical lines are then routed through their respective Isolators and Breakers. This is then fed to the either the THMA transformer for Product Handling and THMB transformer for the Urea Ship loading system, where it is stepped down from 66KV to 12KV and exits the switch yard onto the either THMA MS 1A feeder and bus bar or the THMB MS 1B feeder and bus bar via the circuit breaker. The feed from the THMA bus bar is fed to transformer TML3 to the 20 PC-3 feeder and Bus bar to the 903K switch room while the feed from the THMB bar is fed to the transformer TML4 to the 20 PC-4 feeder and Bus bar to the 904K switch house and the transformer TML5 to the 20 PC-5 feeder and Bus bar to the 905K switch rooms.

903KThis supply via Feeder breaker TML-3 FDR then enters TML3 transformer located south of the 903K switch house at Product Handling. The TML3 reduces the voltage to 480V which then supplies power via the Circuit Breaker 52-3 BRKR to the main bus 20-PC-3. This panel has Incoming Feeder voltage and Bus bar voltage meters with auxiliary relays, switch gears, indicators and reset stations. There is also a transformer inside the substation that reduces a 480V feed from the main bus to 220V/110V for lighting and other auxiliaries.The main bus then supplies power to the different sections of the board as follows:South SideSection 1600A, 480VSection 2600A, 480VSection 3600A, 480VWASA Booster Pump03-MMT-350/2 (Cycle 1)Section 4800A, 480V03-MMT-350/1 (Reclaim Belt)Section 5- Incoming feed from TML-3 Breaker 43-52Main Breaker 1-52Lock out RelayIncoming Feeder Voltage meterBus bar Voltage meterSection 6400A, 480V03-LB-SC-301 (Portal Scraper)Soft Starter for MT-350/External 120 VAC Trip supply North SideSection 1600A, 480VSection 2600A, 480VSection 3600A, 480V03-MMC-301 TripperSection 4800A, 480VPDP 3(Main Bk2 Thermo vents Fans)

904 & 905 K Electrical Distribution905KThe Product Handling system also covers partly the electrical supply for the Cycle 2 (Urea ship loading system). Feed to the transformer is designated for the Urea ship loading supply. The voltage exiting the transformer is 4160V and exits the Urea switch yard onto the MS-1B bus via Circuit Breaker 152B. This bus supplies feeds to the 904K and 905K substation. A supply via Feeder breaker TML-5 FDR, then enters TML5 transformer, along with 905K Substation, is located north of the MT-342 conveyor corridor along the PLIPDECO port access road. The TML5 steps down the voltage to 480V which then supplies power via the Main Breaker 52-5 BRKR. This bus supplies a feed via Feeder breakers to the MT-339 and MT-341 conveyor systems. There is also a transformer inside the substation that reduces a 480V feed from the main bus to 220V/110V for lighting and other auxiliaries (905K).

904KThe other supply via Feeder breaker TML-4 FDR, then enters TML4 transformer, along with 904K Substation, is located north west of the 2202L---4 Hypo chlorinator. The TML4 reduces the voltage to 480V which then supplies power via the Main Breaker 52-4 BRKR located on the main bus 20-PC-4. This bus supplies a feed via Feeder breakers to the MT-342N, MT-342S and 03LD302 Urea Ship Loader conveyor systems. There is also the Soft-Start unit for the MT-342N/S motors. There is also a transformer inside the substation that reduces a 480V feed from the main bus to 220V/110V for lighting and other auxiliaries.

2301K Electrical Distribution2301K Electrical Distribution system is fed from two separate 66kV T&TEC supply that enters the Demin Plant. These electrical lines are then routed through their respective Isolators and Breakers. This is then fed to the either the 1A or 1B transformer, where it is stepped down from 66KV to 12KV and exits the switch yard onto the either the 1A bus bar or the 1B bus bar via the feeder bars and circuit breakers. The feed from the 1A bus bar is fed to the 3A transformer where it is stepped down from 12KV to 4160V and fed to the 3A bus bar and then to the breaker for the Sea water makeup pump (2204JAM), while feed from the 1B bus bar is fed to the 3B transformer where it is stepped down from 12KV to 4160V and fed to the 3B bus bar and then to the breaker for the Sea water makeup pump (2204J).

2310K Electrical Distribution2310KThe Electrical system at 2310K (SP1) is fed from a T&TEC 12kV supply which enters PLIPDECO compound and then to SP1 via an Air Break Switch. This supply then enters T8 transformer located west of the 2310K switch house at SP1. The T8 steps down the voltage to 480V which then supplies power via the Main Isolator to the main board and distribution via respective Feeder breakers, to the equipment. This panel has Incoming Feeder voltage and Bus bar voltage meters with auxiliary relays, switch gears, indicators and reset stations. There is also a transformer inside the substation that reduces a 480V feed from the main bus to 220V/110V for lighting and other auxiliaries.The main board then supplies power to the different sections of the board as follows:2205JM FW Electric Pump 2202L 01/02/OSBL Hypo-chlorinator2205JAD FW Diesel Pump engine Battery ChargerEMCC Emergency board loadsSP2 Pier Extension Isolator Feeder

2610 K Electrical Distribution2610KThe 2610K switch room powers the 04 equipment at the port includes the 2202L---4 Hypo-chlorinator, 2208J (north) and 2208JAM (south) Sea Cooling Water Make-up pumps. The power supply to these equipment comes from the 04 plant switch yard. The 101JG (Air Compressor Turbine-Generator) at 04 supplies 13.8kV. This 13.8kV supplies a feed, to either TR-105 or to TR-106 (Normally Closed). Bus B has a Backup 13.8kV feed (Normally Open). A 66kV T&TEC supply enters the 04 switch yard and is step down via TR-100 transformer to 13.8kV. If power is lost on the Normal 13.8kV Bus A Auto Transfer System would close supplying a fed to Bus B and Bus A. Two 13.8 kV supplies exits the 04 plant switch yard to TR-106 transformers yard located east of the 2202L---4 Hypo-chlorinator.

TR-105 and TR-106 each take the incoming 13.8 kV feed and reduce the voltages to 4160V. These two transformers are incorporated into a Main-Tie-Main Auto Transfer system. Normally TR 105 Circuit Breaker is Open. TR106 transformer is in service supplying power to the board. In the event there is a problem with the transformer in service, the Auto Transfer Switch closes to supply power to the Main board. The 4160V is fed to the Main board inside the 2610K switch house. The 4160 V is then distributed via Feeder breakers to the 2208JM (north) and 2208JAM (south) Sea Cooling Water Make-up pumps, each with respective isolators, trip/reset controls, running amperage meters and indicators. Another 4160 kV feed is taken from the Main board and sent to the TR-107 transformer, located east of the TR-106 transformer, which steps down the voltage to 480V, which supplies the 2202L---4 Hypo-chlorinator and associated equipment on the MCC 007 board. There is also a transformer inside the substation that reduces a 480V feed from the MCC0 07 board to 220V/110V for lighting and other auxiliaries. There is also a battery bank system that is continually being charged at 135 V and between 0.8 to 1 Amps. This is to safely shutdown any of the two 04 Sea Cooling Water Make-up pumps in case of power problems.
