OMICRON CP-TD1 from Brandis Hire

High-voltage source for partial discharge measurement.

Category: Tag:
Business Name


The 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. Also available as a High-
voltage source for partial discharge measurements

The CP TD1 accessory is used in combination 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 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
