Current Transformer Testing

CT/PT TESTING

Current & Voltage Transformers are integral part of Power System as they provide Inputs for Metering & Protection devices. Testing Services are conducted using highly advance State of Art CT/PT analyzer with accuracy of 0.1% for all types of CT/PT ( ie Protection of Metering Class) . After Test automatic software generated reports with time stamping are submitted .

Tests for Current Transformer:

  • Excitation curve and parameters test
  • Turns ratio test
  • Ratio and phase error test
  • Polarity mark check
  • Winding resistance measurement
  • Secondary loop burden measurement
  • Error line curve test for protection CT
  • Transient CT parameters test
  • CT nameplate guess
  • Saturation hysteresis loop curve measurement

Tests for Voltage Transformer:

  • Turns ratio and phase angle error test
  • Polarity test
  • Secondary burden test
  • Winding resistance test

Earth Integrity Testing

Earth Testing

The main reason of earthing in electrical network is safety. When all metallic parts in the electrical equipment are grounded and the insulation inside the equipment fails there would be no dangerous voltages in the equipment casing.

If the live wire touches the grounded casing, the circuit will short and fuse will blow immediately. There will not be any dangerous voltage after the fuse is blown. We test the integrity of your system by using State Of Art Equipment based on fall of potential method & other advance derived methods . Equipment used are having AFC feature ( Automatic Frequency Controller)  function for getting better stable results in noisy surroundings of HV Switchyards .

Thermal Imaging

Thermal Imaging

Thermal Imaging, also known as Thermography, is a technique for producing an image of invisible infrared light emitted by objects with the use of a thermal imaging camera. Thermal imaging cameras provide rapid scanning of a surface that is nondestructive and environment friendly, which allows for quick detection of potential problems or defects that will reduce troubleshooting time and preventive maintenance.

We have high quality thermal imager cameras upto  640 X 480 Pixel resolution to present you a detailed and elaborated thermal view of your critical assets .
