hps testing capabilities

Short Circuit Testing Capabilities • Interruption Tests • Fault Making Tests

• Generator Control HMI – Generator terminal voltage typically reaches the desired test voltage within 5 seconds of the exciter start command Data acquisition • Hioki 8741 Memory Recorder Records: - Up to 20 MHz sample rate - Voltage A-D conversion of 2,000 levels - Voltage resolution from 0.05 mV to 200 mV per sample level • Digital waveform data is stored in .csv format readily shareable with customers and engineers Timing Control Control of breakers, closing switches and other test timing devices are integrated into a single PLC control system

- Voltage frequency control with up to 0.3Hz variability - Meets the operating frequency requirements of many new industry standards and customer demands • Peak, Momentary, and Short Time Current Withstand Tests • Capacitor Switching, Load Switching and Cable and Line Charging Tests • Dual Source/Thermal Kill Arrester Performance Tests • Insulator Power Arc Test Lab Features: Short Circuit Control Room • Continuous observation during tests for visiting engineers and customers • Remote oscilloscopes • High speed photography – Uses a Vision Research M310 High Speed Camera to record high power tests at megapixel image quality with recording rates exceeding 16,000 frames per second
