Troubleshooting

In the case of errors, e.g. unexpected or incorrect values, inverse power:

• Check the settings of the measuring device on the basis of its operating instructions.
• Check whether the current transformer is mounted on the intended conductor in the direction of the energy flow.
• Check the connection of the current transformers and the corresponding voltage tap-off if the active and/or reactive power does not correspond to the expected values; if necessary, one phase has been reversed.
• Check whether the current transformer is connected correctly.
• Check the power requirement of the conductors and measuring devices connected to the current transformer. It must not exceed the rated power of the current transformer (see name plate).
• If the above points do not solve the problem:
  Check whether there is dust or other dirt between the two parts of the core. If so, clean the surfaces carefully with a lint-free cloth.
• Avoid hand contact (sweat)!
