The Omicron CP TD1 is a high-precision test system for on-site insulation tests of high-voltage systems, including power and instrument transformers, circuit breakers, capacitors and isolators. It can also be utilised as a high-voltage source for partial discharge measurements

The CP TD1 accessory is used in conjunction with the CPC 100 for tan delta, dissipation factor and capacitance measurements. Using a frequency sweep method allows increased sensitivity of the test and helps to better assess the insulation quality and detect defects at an early stage. Measurement frequencies range from 15 Hz to 400 Hz and Output Voltages up to 12kV.

The CP TD1 includes a high-voltage source, reference capacitor and measurement electronics. It can generate output voltages up to 12 kV, currents up to 300 mA and achieves laboratory precision, even in environments with strong interferences.

Standard Accessories: Refer accessories list in user manual
Power Supply: Directly powered from the CPC100 instrument
Voltage Output: 0 to 12kV AC
Output Frequency: 15-400Hz
Frequency Resolution: 0.01Hz
Operating Temperature/Humidity Range: -10 to 55°C and 5 to 95%RH (no condensation)
Dimensions (W x H x D) (CP-TD1 and Case): 700 x 500 x 420mm
Weight (CP-TD1 and Case): 38.1kg
Dimensions (W x H x D) (Cables, Accessories and Case): 680 x 450 x 420mm

Key Features

  • Compact and rugged all-in-one test set
  • Wider frequency range for increased sensitivity (15 Hz – 400 Hz)
  • Testing at variable frequencies for improved condition diagnosis
  • Excellent suppression of mains frequency interference fields
  • High-voltage source for partial discharge measurements up to 12 kV
  • Can measure capacitance and dissipation factor (power factor) with laboratory precision
  • Simple transport with a trolley, its heaviest component at just 29 kg
  • Suitable for testing insulation conditions of transformers, generators and high-voltage systems


  • Power transformers — The CP TD1 plays a vital role in ensuring the reliability and safety of power transformers. It conducts comprehensive insulation tests, helping to detect potential defects and deterioration early. This early detection is crucial in preventing costly failures and maintaining efficient energy transmission.
  • Rotating machines — For rotating machines, the CP TD1 is indispensable. It accurately assesses insulation quality, which is crucial for the longevity and efficiency of these machines. Regular testing with the CP TD1 can prevent unexpected downtime and extend the life of the equipment.
  • Current transformers — The CP TD1 is essential in evaluating the insulation integrity of current transformers. It guarantees that these transformers function reliably under high voltage conditions, which is critical for the safety and efficiency of electrical systems.
  • Voltage transformers — By identifying potential insulation issues early, the CP TD1 helps maintain voltage transformers’ operational integrity and reliability, which are crucial for stable electrical distribution.
  • High-voltage (HV) cables — In the case of HV cables, the CP TD1 helps assess their insulation condition. This is vital for preventing power outages and ensuring the safety of the electrical network. Regular testing can detect insulation weaknesses before they lead to failures.
  • Gas-insulated switchgear (GIS) systems — For GIS systems, the CP TD1 offers precise testing capabilities. It helps maintain the reliability and safety of these systems by detecting insulation defects, which are crucial for the uninterrupted operation of power grids.
