Tan Delta Test Set – TDM 4000
ENERGY
The TDM-4000 is an automated instrument for measuring the electrical characteristics of transformer oil, insulating liquids & other insulating material samples. The TDM-4000 measures Capacitance, Dielectric Constant (Î), Dielectric Loss, Tan Delta (Dissipation Factor), Resistance & Resistivity of the test sample. The Tan Delta value gives an indication of the condition of the oil sample. There are several reasons due to which the Tan Delta value may be affected – such as moisture, dissolving of some of the transformer varnish, insulating material deteoriating etc.
TDM-4000 is especially designed to work with the IEC & ASTM type oil cell with a 2mm spacing and will apply a stress in the range of 100-1200 volts per mm as recognized by ASTM and other specifications.
200 kV High Voltage VLF Test Set
ENERGY
AC testing of cables and electrical apparatus is now easier than ever. With the introduction of the High Voltage, Inc. line of portable and affordable VLF hipots, there is now a practical method of field-testing various loads, particularly cables and rotating machinery. High Voltage, Inc. offers a full line of VLF AC Hipots from 28 kVac to 200 kVac with models that can test up to 50μF of load, cables from 150 feet to 90 miles in length and the largest of generators/motors. Use VLF for AC stress tests and/or our Tan Delta unit with our VLF as the voltage source for cable diagnostics.
Total gas content
ENERGY
Automatic analysis of the dissolved gases in oil-filled transformers
The analysis is done in 2 steps which guarantee a very high selectivity and sensitivity of the determination of dissolved gases:
- Gas separation by means of fully vacuum degassing ( accord. to DIN EN 60567, DIN IEC 599 and IEEE C57.104-1991) and display of results
- Option: Subsequently to the determination of the total gas content a gas chromatographic analysis can be made
