DESCRIPTION Instrument has been primarily designed to produce high voltage surges for pre-location of under ground cable fault in combination with Reflectometer T-510. The surges produced help in pinpointing the fault and tracing the route of the cable when used with acoustic DIGIPOINT surge generator generates D.C. high voltage for pressure testing of the underground cables to find out faulty phase and the breakdown voltage with leakage current. It can also be used as limited burn down instrument.

      DOWNLOAD Pulse Echo, Impulse Current, ARM & Decay method. 10 Arc graphs + 1 reference graph for accurate & certain fault distance. Five waveforms for comparison. Easy to use Cursor. Large graphs storage capacity. Online support for experts reviews the fault graphs. Compact small, light weight design. Suitable to operate on mains (220-230/240 VAC, 45Hz up to 60 Hz) or portable generator. PRODUCT DESCRIPTION Reflectometer T510 is a Laptop based Digital Time Domain Reflectometer for pre-location of faults in Power Cables. Its state-of-art technology makes it easy to use and yet most reliable for any fault condition. The interactive graphical user interface makes it easy, for even a layman, to pre-locate the fault distance. USB Port makes the device extremely flexible. The device has four working modes namely Pulse echo mode, Impulse Current mode, Decay mode and ARC Reflection mode. Pulse echo mode is useful only for open and shot types of faults. The impulse mode when used with surge generator T1016 or T1020 or T1028 or T1032 to pre-locate fault distance of almost all types of faults including open, short and intermittent faults by way of ICM, ARC Reflection & Decay Method. Decay is suitable for flashing types of fault. The software provides a huge storage capacity so that you may use the Reflectometer T510 test result for future reviews & analysis. The innovative feature of software displays LAST TWO waveforms for comparison purposes. The easy to use cursor makes it simple to pre-locate the fault distance. The VOP (Velocity of Propagation) control makes it easy to precisely pre-locate the fault distance on cables with different velocity of propagation. The test waveforms can be printed as a hardcopy directly from the software. The fault readings can be transferred over INTERNET for further assistance. The software is so programmed that it automatically saves all the test results, so that you never miss any important result. The entire tests are stored on the bases of date and time of the reading taken. PERFORMANCE FEATURES • Digital acquisition of measured data using highly advanced Flash technology in all modes and ranges of measurement. • Easy menu-based operator guidance. • Large-size high-contrast display on monochrome or color screen (15 ″). • Pulse output in bridge configuration for suppressing the display of the transmitter pulse. • Internal compensation in order to enhance fault location at short distance. • High local resolution by using short pulses. • Long locating range due to wide dynamic range. • Quasi-real time operation due to high rate of measurement. • Enhanced fault detectability even in difficult conditions due to averaging of measured values. • Evaluation of reflect graphs by cursor and marker. •Integrated memory for storing the results of all measurements taken in all modes and the data related to them together with the device setups.

Instrument has been primarily designed to produce DC high voltage for High Voltage (Proof Testing) of High Voltage Cables up to 40 KV DC. The instrument is well protected & has zero volt interlock to safe guard sudden exposure of personals. It is continuously variable and produces 0-40 KV DC output, voltage & mA analog meter are provided to note the reading for high voltage applied & leakage current. Voltage & current level can be set by potentiometer on panel. Timer is also fitted to select the time duration of DC test.
