Measurement, Control & Protection

Patented, "complete system" closed-loop compensation controls the entire optical fiber circuit, opto-electronics and measurement outputs to ensure accuracy and stability over the long term. 0.1% accuracy of reading to over 500kA Measurement is immune to external magnetic fields and magnetic materials Superior installation flexibility Industry standard current output signals for plug and play replacement of a wide variety of existing systems. Advanced Accuracy Diagnostics (A2D) monitors both fiber optics and opto-electronics for measurement confidence.

Two light waveforms in phase with each other, but polarized in opposite directions, enter the measurement section of the fiber optics surrounding the bus bar. Due to the Faraday effect, the magnetic field of the bus current shifts the phase of the two waveforms, but in opposite directions. Interfering factors such as vibration also cause phase shifts in the waveforms, but in the same direction. The relative phase shift between the two waveforms is uneffected. Accuracy is maintained. Patented closed-loop full compensation accurately nulls the phase between the waveforms. DynAmp's closed-loop approach encompasses not only the opto-electronics, but the complete fiber 'circuit' and output signals as well. This unique approach automatically compensates for long term gain, sensitivity and repeatability variation. Accuracy is assured over the long term.

• Patented "complete system" closed-loop compensation automatically compensates for any long-term shifts in fiber optics, electro-optics and output signal electronics. In effect, by closing the loop on all parts of the system, accuracy is 'locked'.
