In-depth Power analysis
A full diagnosis, with the help of power analysis, is done of your electrical installation or network with precise measurement, calculation and display of harmonics
Three-Phase Electrical Networks Analyzer – C.A 8335 QUALI-STAR + : E-Power Technologies makes use of the Quali-star to measure all the necessary voltage, current and power parameters for a full power diagnosis of your electrical installation or network. We can measure from 10 V to 1000 V and with VT and CT configurations from lkV to 400 kV. Measurement, calculation and display of harmonics up to the 50th order – complete with Total Harmonic Distortion (THD).
E-Power Technologies can analyze your tariffs and restructure it to best suit your needs, upgrade or improve power supply or help with auxiliary power supplies for your premises.
Actual power recordings
The below current recording shows the start-up of large motor’s, these peaks can influence the hot-spot winding temperature of your transformer. These peaks can be reduced by the introduction of VSD’s. E-power technologies can reduce these peaks by installing/ introducing VSD’s.
