2.1 General description
InteliMains 210 controller is comprehensive mains supervision controller for multiple generating sets operating
in parallel to the Mains. A modular construction allows upgrades to different levels of complexity in order to
provide the best solution for various customer applications. Controllers are equipped with a powerful graphic
display showing icons, symbols and bar-graphs for intuitive operation, which sets, together with high
functionality, new standards in Mains controls.
The controller automatically connects and synchronizes two parts of bus bar and controls the bus tie circuit
breaker (BTB).
The controller provides easy-to-use operation and installation. Predefined configurations for typical applications
are available as well as user-defined configurations for special applications.
2.1.1 The key features of InteliMains 210
Easy-to-use operation and installation. The factory default configuration covers most applications
Various customizations are possible thanks to its configurability
Excellent remote communication capabilities
High reliability
2.2 True RMS measurement
This controller measures AC values based on True RMS principle. This principle corresponds exactly to the
physical definition of alternating voltage effective values. Under normal circumstances the mains voltage
should have a pure sinusoidal waveform. However some nonlinear elements connected to the mains produce
harmonic waveforms with frequencies of multiplies of the basic mains frequency and this may result in
deformation of the voltage waveforms. The True RMS measurement gives accurate readings of effective values
not only for pure sinusoidal waveforms, but also for deformed waveforms.
Note: The harmonic deformation causes that the Power Factor of a generator working parallel with the mains
cannot reach values in a certain range around the PF 1.00. The higher the deformation, the wider the power
factor dead range. If the requested power factor is adjusted inside the dead range, the controller cannot reach
the requested value because of this fact.
