3 UPS System Galaxy kVA Configured as N+1 UPS System Ref: SYSTEM DESCRIPTION The MGE Galaxy 5000 is an on line (double conversion) solid state uninterruptible power supply (UPS) system, rated at 100 kva. This project consists of 1 x 100kVA Galaxy 5000 unit configured as an N system. Each UPS is supplied with a battery to supply a load of pf for 30mins. UPS No.1-1PDK32003 This series of tests results are for the UPS Module connected as an N system. IMPORTANT All the measurements and records will be achieved as stated in the procedure attached hereafter. All measurements and records will be consigned in a test report. The load will be of resistive type via a loadbank.

4 UPS Type 3 x Galaxy kVA Configured as N+1 SIGNATURE IDENTIFICATION LOG Procedure 1. All personnel attending this SAT must be identified including vendor personnel. 2. Print name, department / organisation 3. Record signature, initials and date. 4. SAT Lead responsible to ensure that as a minimum all personnel, who have recorded information during the SAT, have recorded their name on the Signature Identification Log.

5 1.0 BALANCE TEST AT 100% LOAD Objective: Demonstrate the operation of the UPS system voltage regulation on a balanced load Procedure: A test is carried out with all three phases loaded at 100% of system load i.e. 160kW The following are measured at a common output point within the installation: UPS Output Voltages phase to phase, and the three phase and neutral currents Acceptance Criteria: Results within unit specification Results: All OK Comments: Comments Checked By: Date: ( Yes / No )

8 3.0 SYSTEM TRANSFER / RE-TRANSFER TEST Objective: To demonstrate that the UPS system can be commanded to a transferred state by shutting down UPS units in turn and then reversing the procedure to bring the UPS units back on-line. Procedure: The operator will shut down UPS units in turn demonstrating the transfer process and the N+1 operation of the system. Acceptance Criteria: Information correctly represented on client s BMS System / UPS s displays Results: All OK Comments: Comments Checked By: Date: ( Yes / No )

9 The following results show the transfer of the 100% system load from Inverters to Mains 2(Static- Switches) and back to Inverters with voltage stabilization for the load. Load Voltage during Load Transfer Test Load Current during Load Transfer Test

10 3.0 LOSS AND RETURN OF NORMAL AC POWER TEST Objective: Demonstrate the correct operation of the UPS in case of loss and return Of AC mains i.e. UPS switches to battery in case of loss of mains and back to normal operation upon return of mains. Procedure: The UPS module runs normally with load. The input switches Q1 or the Mains 1 supplies to each UPS are switched OFF to represent a mains failure. The load voltage, load current on phases L1, L2 + L3 at the output of the UPS system are recorded. A loadbank will be connected to simulate full system load: 0.8pf. The system will then run on battery for 30 minutes and the end voltage recorded. The system will then be re-charged for 3 hours and the system will then be run on battery for 24 minutes and the end voltage recorded. Acceptance Criteria: UPS system performs correctly Results: All OK Comments: Comments Checked By: Date: ( Yes / No )

15 4.0 SYSTEM (AUTO) RE-START Objective: To demonstrate that the UPS system can re-start on the return of AC mains power. Operation procedures should include all necessary safety steps which will require operator management of the process. Procedure: At the end of battery test 2, allow the system to shut down on low DC voltage. Then restore AC mains and allow the system to re-charge to minimum level and then return to on-line operation with appropriate operator intervention. Acceptance Criteria: System re-starts. Information correctly represented on client s BMS System. Results: All OK Comments: After two hours the BCB will trip to prevent deep discharge. This will need to be closed if necessary.
