Electrical properties

As part of unit certification, the electrical properties of generation units, e.g. wind turbines, combustion engines (e.g. CHP) or photovoltaic inverters, are measured and determined. These measurements are used as the basis for issuing a unit certificate required. The measurements as part of the unit certification are carried out in accordance with FGW TR3, IEC 61400-21 and/or DIN VDE V 0124-100 and documented in a test report. The following measurements and tests, among others, are carried out during the measurement:

We would be happy to discuss the possibility of carrying out FRT tests with you, e.g. on a test bench or at the system location with mobile test equipment.

We are a DIN EN ISO/IEC 17025:2005 accredited test laboratory for the measurement of electrical properties and therefore have proven expertise in the field of type testing and the measurement of electrical properties.

Measurements are also possible within the individual verification procedure necessary. These are carried out after commissioning of the EZA. M.O.E. can also carry out the measurements as part of the individual verification procedure.

We also offer commissioning of the fault recorder as part of the individual verification procedure procedure. This service is usually offered as a complete package with the system certificate C and includes the following points:

If in the course of the system certification If harmonics are found to be exceeded and the system certificate is then issued with the reservation of a metrological proof of conformity (harmonics measurement), system operators must arrange for a harmonics measurement to be carried out within 6 months of the system certificate being issued for the generation system and have this evaluated by the responsible certification body. If the evaluation of the harmonics measurement shows compliance with the limit values, the reservation is acknowledged by the certification body. The reservation from the system certificate is thus lifted. If the limit values from the harmonics measurement are exceeded, the system operator must take measures to reduce the harmonic emissions within one year, which in turn must be confirmed by a measurement. If the system operator does not measure harmonics within six months of commissioning the first generation unit of the generation system, the certification body must withdraw the system certificate after this period has expired. The grid operator may demand that the system be shut down due to feedback that is incompatible with the grid, e.g. harmonics.

In generation systems, interactions between the generation system and the grid can lead to problems in the operation of the generation system. This may result in costly repair/maintenance work or the operational failure of the system. To find the cause of the problem, we offer individual measurements of the electrical properties. The measurement data can be used for troubleshooting in cooperation between the system operator, manufacturer, grid operator and M.O.E.. Possible investigations may include

We support you in troubleshooting by means of individually tailored measurements to find the cause.
