4 4 HR Method At 1.0 Not Adequate 4 hr does not replicate realistic emergency situations Consider multiple day tests up to 5 days Does not provide for adequate transient testing 1.0 power factor does not match real world loads at the facility.9 leading power factor with capacitor becoming more important Not enough run time to validate the system through temperature, testing and installation warranty 4

5 Old Way 4 Hour Method Low voltage load banks (typically 480 VAC) Must be used with step down transformers Systems can come pre wired with all equipment mounted to a single trailer; or can come in separate containers that need to be field connected Low voltage load dbanks and transformer assemblies introduce more components that can fild fail during testing ti 5

6 24 Hour Medium Voltage Load Banks Resistive or reactive load bank Contains resistors or reactors that operate above 690 VAC and below 15,000 VAC Permanent/portable medium voltage load banks often used for commissioning power plants, maritime electrical systems, standby generator systems and substations The most common voltages used are 5kV (4,160V) and 15kV (13,800V) Commissioning power systems 6

11 Industry Case Studies 24 HOUR TESTING, CASE IN POINT 11

12 Water and Wastewater Emergency Power Why Testing Was Needed: Commission proper operation of the entire system from fuel line through transfer switch Generators should be steploaded to accurately reflect system demands and ensure proper emergency load sequencing Transient response, noise, vibration and fuel use rates can be reviewed during the test Prevent disruption of a critical pumping process 12

13 Water and Wastewater Emergency Power Project Scope: 2.8 MW resistive load at 4160V to generator Commission new equipment at pump station 3MW of resistive iti load dbanks, a 7MVA transformer, and switchgear with medium and low voltage cable Labor for unit cable runs and tie in for the transformer 13

14 Data Centers Medium voltage load banks eliminates the use of transformers for testing ti multiple generators in a data center pod Safer for the generator since it is not subjected to fluctuations in voltage and current when a transformer is used to step the voltage down for low voltage load banks 14

15 Oil and Gas Ensure that gas turbine generators continued to work while switching out analog controls for digital controls Generators were absolutely critical to the ongoing operation of the field. If the turbines ever failed future flow rates would have been lost in the oil field With mediumvoltage load banks, the performance of the new digital controls was validated and the continued operation of the field ensured 15

16 Cruise Ships Losing generator power at sea is a catastrophe that makes front page news Medium voltage load bank testing right to the dock before the ship sets sail When a cruise line installs new diesel generators, load bank testing ensures ships keep the lightsonandthe the propellers turning Never have to say DIW Happiness aboard ship 16

17 Always Specify A 24 Hour Test Closing statements Leaving future risk and downtime intact 5 day test to mimic 100 day storm event Generators don t run under water (flood plain operation) Recap Enforce key messages 17
