Wuhan Sangao Electrical Test Installations Limit Co.
Isolation switch is the high voltage switch equipment, it was large and frequently use in power system . The outdoor isolating switch is the only completely exposed in the atmospheric environment electrical equipment, It is also a electrical equipment affected by climatic conditions influence the most direct and most serious. The operating conditions is relatively poor, It is easy to generate fault of mechanical or electrical. Especially the finger contact part is easy to be affected by rain, dust and harmful gas invasion, resulting in poor contact caused fever, provide the spring with contact pressure due to heating and annealing for reducing the pressure, so that more cause finger heat form vicious spiral eventually burn out finger accident. In maintenance often only pay attention to replace the obvious failure and fracture of spring, but spring to reduce the pressure can not judge and replacement, so again in the operation, each finger current distribution by the pressure difference, The greater the difference between the current distribution is not uniform, long-term operation will occur is bad and the overheating. Fever finger will be vicious spiral, a finger contact bad will spread over the entire bad contact. At the same time, there are a lot of isolating switch contact pressure can be adjusted, if in maintenance adjustment pressure is not enough or each finger to adjust the pressure difference will also appear afore-mentioned phenomena.

BVR Series -
IBEKO Power AB
Battery voltage recorders from BVR series are designed to serve as a support tool for cell voltage measurement during battery capacity testing.During capacity testing, cell voltage, temperature, inter-cell connection voltage, and specific gravity should be measured in order to determine failling cells in the string that should be replaced.Furthermore, IEEE standards for stationary batteries applications stipulate periodical measurement of overall string voltage, as well as cell voltage and temperature.The BVR Series is the perfect tool for that purpose. All measurements are automatically saved in device’s internal memory. Additionally, DV-B Win software helps the user to download all measured results. Furthermore, the user can create test reports and export them to various formats.BVR series includes two models: BVR11 and BVR22. These are rechargeable handheld devices intended for performing monthly battery inspections and support tools during capacity testing. The list of the applications of these instruments includes:Efficient supplement to BLU series of battery load units during battery discharge testingMonthly inspections of large battery banksAmbient temperature measurementCurrent measurement using current clampsUSB and Bluetooth communication with PCSimultaneous string voltage and current measurement to analyze a discharge test processThe BVR22 model provides Bluetooth communication with an external density meter, for transferring electrolyte specific gravity and temperature readings.

BAE Systems Inc.
We have advanced the multiple-object tracking radar concept with an innovative application to meet today’s test range needs. The iMOTR features enhanced clutter suppression capabilities to deliver clearer, more accurate assessments of object launch trajectory and flight path data on airborne and low flying objects. This tracking information can then be handed-off to other radars or data collection sensors in real-time. The system is also better equipped to provide precision time, space, and position information (TSPI) data of multiple objects in flight over a wider field of regard than the current test range radars in service.
