CP TD12/15

Module for capacitance and power/dissipation factor (tan delta) measurements

Powerful accessory

The CP TD12 and CP TD15 are accessories for TESTRANO 600, CPC 100 or CPC 80 for performing power/dissipation factor and capacitance measurements.

The CP TD12 and CP TD15 include a high-voltage source, reference capacitor and measurement electronics. It can generate output voltages up to 12 kV respectively 15 kV, currents up to 300 mA and achieves laboratory precision, even in environments with strong interferences.

Variable frequency
The CP TD12/15 enables you to perform a frequency sweep from 15 Hz to 400 Hz. This increases the sensitivity of the test and helps you to better assess the insulation condition and detect defects at an early stage.
Portable and lightweight solution
Its compact and lightweight design (≤ 24 kg / 53 lbs) makes the CP TD12/15 easy to transport by one person and ideal for on-site testing, especially in areas with limited space.
Precise and reliable results
The CP TD12/15 module is designed to produce reliable, repeatable and exceptionally precise results by offering excellent noise suppression even under extreme conditions.

Determinable parameters

Using our CP TD12 respectively CP TD15 combined with TESTRANO 600 or CPC 100/80, you can determine a wide range of electric and dielectric parameters:

  • Power factor (cos φ) / dissipation factor (tan δ)
  • Capacitance
  • Exciting current
  • Watts / power (P, Q, S)
