Description
Combined with the CPC 100, the CP TD1 measures the capacitance and dissipation factor (power factor) with laboratory precision. This allows the insulation condition of transformers, generators and other parts of high-voltage systems to be tested according to IEEE 62 (C57.152), IEC 60076-1 and -3, as well as the CIGRE “Guide for Transformer Maintenance”. As recommended in the CIGRE Guide, testing is performed at variable frequencies to better diagnose signs of aging in insulation. The portable test system (max. 29 kg per component) can also generate output voltages of up to 12 kV.
Key features
- Testing at variable frequencies – better diagnosis of signs of ageing in insulation
- Simple transport thanks to trolley – heaviest component just 29 kg
- Excellent suppression of mains frequency interference fields
- Automated testing – via PC using the Primary Test Manager software or via the user interface of the CPC 100 (includes testing templates)
- Reporting – Detailed analysis with trend displays and graphics
Applications
The following variables can be measured by extending the CPC 100 to include the CP TD1:
- Capacitance
- Dissipation factor tan δ (tan delta)
- Power factor cos φ
- Watt losses
- Power (effective power, apparent power, reactive power)
- Impedance (absolute value, phase, inductance, resistance, quality)
