Mil Standard 1399 Testing
This interface standard for shipboard systems is the approved testing protocol for naval sea standards and all relevant departments within the US DOD. The electric power system serves a variety of user equipment including aircraft elevators, communication systems, weapon systems, and computers. The testing protocol is used to verify compatibility with a prescribed list of characteristics and tolerances--transients, sags and spikes, unbalance, frequency tolerances and characteristics and harmonics. Recommended testing apparatus—a voltmeter, frequency meter, oscilloscope, harmonics meter, and current transformers—can all be replaced with one instrument, the Power Xplorer PX5-400.
Power Measurement
Equipment being used in these applications must be tested in all operating modes, including 400 Hz, to ensure that critical test and operational equipment fits with the power supply. The Power Xplorer PX5-400 collects a range of parameters—from load-related factors such as watts, VA, VAR, frequency instability, power factor and load excursions—to power quality information including sags, swells, transients and harmonics. Users can select the length and mode of data collection, including troubleshooting, data logging, power quality surveys, energy and load balancing.
Troubleshooting
The Power Xplorer PX5-400’s unique annunciator "report card" provides instant power quality answers in the field. A wide range of power monitoring data is collected, analyzed and tabulated in color-coded categories to quickly identify areas of concern, which are identified in red. Drill down for more detailed information by simply touching the intuitive touch screen to locate the source and pinpoint the root cause of power quality disturbances.
Fast Transient Capture
The Power Xplorer PX5-400 uses digitized high-speed sampling to capture and analyze microsecond-wide transients (Dranetz 658-like and BMI 8800-like). Transients, generated by fast-switching electronics, computer systems, aircraft components, and load transfer are immediately characterized as impulsive or oscillatory and detailed for further analysis. The Power Xplorer PX5-400 delivers a full profile, with events time stamped to the millisecond of the entire transient, to pinpoint the exact source and cause of the event.
Power Quality Diagnostics
The Power Xplorer PX5-400 has a built-in event characterizer that labels events to directly support troubleshooting and the gathering of survey data—for improving power quality and equipment reliability, as well as for matching the requirements and susceptibilities of that equipment to the incoming supply. Plus, the Power Xplorer PX5-400 captures detailed harmonics, interharmonics and subharmonics to effectively troubleshoot the complex problems caused by these events.
Equipment Testing
Evaluating and testing the performance of military components and computerized systems under true operating conditions—400 Hz or other—is key to ensuring a successful mission. The Power Xplorer PX5-400 incorporates advanced features such as RMS triggers, advanced transient capture, and cross triggering between channels to ensure that all equipment is working properly. Plus, real time reading observing during testing, startup and maintenance enable users to see results and tweak equipment on the fly.
