Energy Technology

New quality requirement taking into account the future international network connections, as well as the decentralized energy supply

 

Here, HERO®power is a strong partner when it comes to simulating real networks. Standardized networks only define harmonics up to the 50th harmonic.

The research deals with real and future networks: feed-in node, lightning strike, feed-in in the European network, network impedance monitoring.

 

Network simulation of real networks

Here, dynamic properties are required that go far beyond the standard requirements. Network dips and distortions go far beyond 2.5kHz, up to frequencies in the 100kHz range.

A special position is taken by the HERO®power PFL2250-28-UDC415-IDC375.

These tasks also place high demands on the current measuring equipment.

Here is also the connection to metrology.

The electrical quantities current and voltage, which serve to calculate the power, must be detected both as broadband and have a negligible phase shift in the lower μ-degree range between the current and voltage measurements.

In order to detect currents floating, the galvanic isolation must be broadband and stable.

 

Power Calibration

Metrological institutes like PTB, Metas, VDS—AIT appreciate the precision and dynamics of the HERO®power calibration sources.
