CP TD1
CP TD1 - 1
The CP TD1’s output and the connected cables carry life-hazardous voltage or current.
► Always obey the five safety rules and follow the detailed safety instructions below.
Note: The safety instructions relevant to the CPC 100 and its accessories (refer to page
Preface-1) also apply to the CP TD1. This section lists safety instructions that exclusively apply
to the CP TD1.
Handling cables
► Do not use any other cables than the ones supplied by OMICRON electronics.
► Do not connect any cable to the test object without a visible grounding of the test object.
► Never remove any cables from the CP TD1 or the test object during a test.
► Always turn off the CP TD1 completely before you connect or disconnect any cable
(disconnect the CPC 100 from mains or press its Emergency Stop button).
► The high-voltage cable must always be well attached and tightly connected to both the
CP TD1 and the test object. A loose or even falling off connector at the test object carrying
high voltage is life-hazardous. Make sure the connectors are clean and dry before
connecting.
► At the CP TD1, press the high-voltage cable’s plug to the connector tightly and turn the
screw cap until you feel a mechanical stop. If you notice a rough-running of the screw-cap,
clean the screw thread and use a lubricant (vaseline recommended).
► Tighten the plugs manually. Do not use any tools for that because that can damage the plugs
or connectors.
Insert the yellow banana plug (the high-voltage cable’s grounding) into the respective plug
socket.
► The high-voltage cable is double-shielded and therefore safe. However, the last 50 cm (20
inch) of this cable have no shield. Therefore, during a test consider this cable a life wire and
due to the high voltage life-hazardous.
► Keep clear from zones in which high voltages may occur. Set up a barrier or establish similar
adequate means.
► Both low-voltage measuring cables must always be well attached and tightly connected to
the CP TD1’s measuring inputs IN A and IN B.
Make sure to insert the red and blue marked cables into the corresponding measuring
inputs: IN A = red, IN B = blue.
Tighten the plugs by turning them until you feel a stop.
► Tighten the plugs manually. Do not use any tools for that because that can damage the plugs
or connectors.
The CP TD1 is an optionally available high-precision test system for on-site insulation tests of
high-voltage systems like power and measuring transformers, circuit breakers, capacitors and
isolators. With the add-on device CP TD1, the CPC 100 increases its range of possible
applications into high-voltage measurements.
The internal switched mode power amplifier enables measuring at different frequencies without
interferences with the mains frequency. Automatic test procedures reduce the testing time to a
minimum. Test reports are generated automatically.
The CP TD1 comes with its own test card named TanDelta (Tangent Delta), which provides
highly accurate measurements of the capacitance Cx and the dissipation factor tan (DF) or
power factor cos (PF), respectively.
Both the dissipation factor and the power factor grant information about possible losses in the
insulation material, which are increasing with age and water content. A change of Cx is a
warning indicator for partial breakdowns between the layers of a bushing or a capacitor.
Additionally, the CP TD1 measures the following quantities:
• Actual, apparent and reactive power
• Quality factor QF
• Inductance
• Impedance, phase angle
• Test voltage & current
The CP TD1 works as an add-on device to the CPC 100. Do not connect the CP TD1 to any
other device. Do not use the accessories for applications not indicated in this User Manual.
Note: Any other use of the CP TD1 but the one mentioned above is considered improper use,
and will invalidate all customer warranty claims and exempt the manufacturer from any liability
to recourse
