2840 [ High-Precision C, L & tan δ (Dissipation Factor) Measuring Bridge ]
Accuracy capacitance 0.02%, tanδ 1x10E-5
The High-Precision Dielectric-Loss Analyzing System 2840 is designed for measurement of very low dielectric losses and impedances (Dissipation Factor and Power Factor) of high-voltage apparatus (e.g. extruded insulation on power cables). The instrument works on the principle of a combined bridge-vector-meter and is capable of analyzing capacitive and inductive loads – especially shunt reactors – with outstanding accuracy and stability certified by a leading metrology institute.
Advanced software functionalities such as insulation temperature correction, programmable test sequences with pass/fail limits, graphical visualisation of measured data, etc. make this instrument a powerful tool for analysis of high-voltage equipment.
