Meter relays - Import export

The IEC 6185092 LE Merging Unit is the optimal solution for process bus interfacing. It allows the consolidation of measurements made in the switchyard, feeding protection relays, meters and fault recorders located in the control room. The use of fiberoptical communications makes it inherently safe. By eliminating the majority of copper wiring, the CSN® Merging Unit addresses key technical and logistic challenges affecting the cost of substation design, construction and maintenance. The simple and disturbancefree architecture of the open IEC 6185092 process bus allows operation of relay, meter and faultrecording equipment of different manufacturers on the same bus. The IEC 6185092 LE Merging Unit collects data from conventional instrument transformers and converts the analog signals into a digital protocol

Fast and accurate measurements of the smallest resistance values are possible with the milliohmmeter RESISTOMAT® model 2316. Due to the rugged aluminium injection moulding desktop housing with membrane keypad it is suitable for use in laboratory and industrial environment likewise. Wires and coils can be measured with temperature compensation. The temperature of the sample is measured with a Pt100 or pyrometer and the resistance is then corrected to the equivalent at e.g. 20 °C (adjustable) in the instrument. The application range is very wide such as the measurement of: — transformer motor coil windings — coils of all kind — cables and wires on the drum or as meter samples — switch and relay contacts — heating elements — fuses — connections and transitions at power rails and many more Specific characteristics: — Autorange — Temperature compensation for all materials — Thermal e.m.f. compensation — Input voltage protection up to effectively 400 V rms
