Konica Minolta Sensing Americas, Inc
Instrument Systems General Accessories current range of optical probes and measurement adapters using fiber optics as a means to transport light in the spectrometer was a primary goal sought by Instrument Systems from the beginning of their product development. With the increased research and the recent advances made in fiber optics it is a goal that has come to fruition. Having striven to incorporate fiber optic technology into their spectrometer systems. Instrument Systems has been working on creating top of the line fiber optic accessories. This not only diversifies the already wide application possibilities for Instrument Systems Spectrometers, but makes them more universally and effortlessly installed. Whether it’s measuring spectral transmission properties in normal light incidence, measuring ultra violet or infrared, or collecting radiation and measurements of irradiance, Instrument Systems has developed an accessory to meet your specific needs. For simplicity and ease of use Instrument Systems has made all of their accessories “plug-and-play”. This means installing and expanding the capabilities of your Instrument Systems Spectrometer has never been easier.

Scope T&M Pvt, Ltd.
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.
