Its proven technology provides safe, reliable and accurate measurements of insulation resistances up to 15 TΩ, with 4 pre-selected test voltages, 500 V - 5 kV - 10 kV - 15 kV. Other test voltages may be selected in steps of 25 V, 100 V or 500 V. 

A state-of-the-art microprocessor controls the equipment operation and enables the incorporation of advanced features which make measurements easier: auto-range selection, 16,000 readings memory, AC/DC voltmeter, automatic measurement of Absorption Index and Polarization Index, leakage current and capacitance measurement, timer enabling programming of test duration, configurable Pass-Fail test, Step voltage test, real time clock and calendar. Built-in chronometer, indicating elapsed time, in minutes and seconds, since the test started, up to 90 minutes. 

Measured values are transmitted through the USB interface and are printed in the built-in printer as a registration of the performed test.The MD-15KVR has a Bluetooth interface that allows remote control of it through a Android device with BlueLogg software. With it you can take the photos of the objects under test and the GPS coordinates of each. It also allows you to record voice comments for each measurement.

SCOPE introduces state of the art precision single phase Transformer Turns Ratio Meter (TTRM ) designed for field testing as well as factory testing of power transformers, instrument transformers and distribution transformers of all types. TTRM 101 measures only turns ratio where as TTRM 102 along with turns ratio, measures ratio deviation, phase angle deviation, magnetizing current and detects tap-position of single phase transformer in charged switchyard condition. The range of AC voltage selection offers high accuracy in measurement.Both the instrument have in-built TFT display with touch screen and thermal printer. The user friendly, simple instrument makes the testing more easy. With the touch keypad it is possible to enter required DUT information.The ratio results are displayed with % error. Internal non-volatile memory gives the provision of storing test results.Further data can be downloaded to PC or copied to memory stick through USB port provided.

The C-Trans-software, gives the flexibility to download the stored results to PC and do the further analysis and report generation.

Features

  • Different voltage ranges provided for more accurate results
  • 5.7” TFT display with touch screen and simple menus to operate TTRM
  • Facility to configure transformer ID and details
  • Automatic OLTC operation for tap change
  • Date and time stamping to results
  • In-build memory to store the test results
  • Thermal printer to take quick print out for record
  • Ethernet port for PC interface to transfer records to PC Software
  • Mass storage device (USB 2.0) interface for copying records in pen drive
  • Lightweight, portable instrument household in rugged moulded case
