Capacitance & Tan Delta (Dissipation Factor) Testing Service – Using Advance  OMICRON /MEGGER Test Kit

We provide high-accuracy Capacitance and Tan Delta Testing Services using advanced OMICRON Electronics Test Kits, ensuring reliable condition assessment of high-voltage electrical assets. This testing is essential for evaluating the health, insulation quality, and ageing condition of critical power equipment.

  • Capacitance Test measures the dielectric constant of insulation and detects physical deterioration, moisture ingress, or partial insulation damage.

  • Tan Delta (Dissipation Factor) Test measures dielectric losses in insulation, indicating ageing, contamination, moisture, or insulation defects.

An increase in Tan Delta value directly reflects insulation degradation and potential failure risk.

Testing Methodology:

  • Test conducted using frequency-based and standard Tan Delta methods

  • Accurate measurement under controlled voltage and frequency conditions

  • Comparison with IEC / IEEE standard limits

  • Trend analysis with previous test data (if available)
