CP TD12/15

Capacitance/dissipation factor testing device (tan delta)

The CP TD12/15 accessory is used in combination with TESTRANO 600, CPC 100 or CPC 80 to perform power/dissipation factor and capacitance measurements.

It enables you to perform power/dissipation factor and capacitance measurements from 15 Hz to 400 Hz. This frequency sweep increases the sensitivity of the test and helps you to better assess the insulation condition and detect defects at an early stage.

The CP TD12/15 includes a high-voltage source, reference capacitor and measurement electronics. It can generate output voltages up to 12 kV / 15 kV, currents up to 300 mA and achieves laboratory precision, even in environments with strong interferences.

Key features

  • Testing at variable frequencies for better condition diagnosis
  • Portable component and simple to transport using a trolley
  • Excellent suppression of mains frequency interference fields
  • Wider frequency range for more sensitivity (15 Hz – 400 Hz)
  • High-voltage source for partial discharge measurements
