This set includes Bridge Model:MLS11DS & HV Power Supply model :HLS12SA necessary cables & very flexible, user friendly.Temp correction for the tan delta of object is automatically done as per IEC.Suitable for measuring C & Tan delta for generators, transformers, bushings, circuit breakers,cables, motors at various test voltages upto 12kV.
- 1. Direct reading No calculation required
- 2. Indication of Test Voltage / Leakage Current / Capacitance Value / Tan delta value Temperature and Humidity.
- 3. Data logging with graph of voltage vs Tan to know the tandelta gradient & data analysis for comparison with old results / manufacturer's data in PC Side Software
- 4. As per IEC Temperature correction for Tandelta @ 20Deg.
- 5. Executes all the test modes/voltage automatically once fed .
- 6. Built in Thermal Printer for ON site printout.
- 7. Interference suppression unit provided to work in switchyard under heavy induction.
- 8. 100 Results Data-storage.
- 9. Built in Temperature and Humidity.
- 10. Mode of operation:
- 1) UST - Ungrounded Specimen test - This mode is used when the object under test is not grounded. This testprovides most accurate results.
- 2) GST - Grounded Specimen test. This mode is used when the object under test is permanently grounded.
- 3) GSTg - Grounded specimen test with guard. 3 combinations. This mode is used for measuring them stray capacitances and separating them from basic measurement in GST mode.
