MI 2077

Advanced, digital HV measuring instrument with maximum test voltage up to 5000 V DC and resistance measuring range up to 5 TΩ.

• Automatic PI, DAR and DD index calculation and capacitance measurement up to 50µF.
• Adjustable test voltage from 250 V to 5000 V in 50 V steps.
• Resistance measuring range 5 TΩ.
• Adjustable measuring time from 1 second to 30 minutes.
• Automatic load discharge after completing measurement.
• Guard terminal for elimination of insulation surface currents.
• AC and DC voltage measurement up to 600 V.
• Internal memory module stores up to 1000 measuring results.
• Optional: 110 V version.

The SG5002 \ SG5003 \ SG5008 \ SG5009 high current  resistance meters are special designed for high performance measurement of high inductance, low value resistances such as transformer windings, motors, breakers, switchgear etc. Unlike normal resistance meters these instruments have a built-in high-speed discharge circuits for safe discharge of the stored energy in a measured inductance.

Operation is fully automatic and the powerful DC test current produces high accuracy and rapid saturation of the test object. So virtually all sizes of transformers can be measured.

Three Gorges Project is attracting worldwide attentions. Transformer capacities monoblock 840 MVA . is the best in the homeland . It was made by Siemens Germany, Baoding Tianwei, and Shenyang transformer factory together. SG5101 High Current Winding Resistance Meter has been specially developed to resolve the difficult problem that temperature-rising tests have been suitable to the request that 220kV and the transformer above 220kV temperatures test. It has passed the strict acceptance check , and has reached advanced world level , filling in the blank in homeland .
