The Sonel MZC-310S is one of the most technically advanced short-circuit loop impedance meters available on the market. The device can measure short-circuit loop impedance in consumer and distribution networks protected with high-current circuit breakers. Additionally, the shock and contact voltages can be measured at the same time.
How to use Impedance Meter Sonel MZC-310S?
It has user-friendly interface with intuitive controls. Simply connect the test leads to the appropriate electrical points and the meter will automatically perform the necessary measurements. Where the condition for automatic power off cannot be satisfied, the facility may be authorized to operate on the basis of the voltage criterion. The application of the four-wire method and the flow of the measuring current in the 150/280 A pulse determine the high precision of the performed test. This single device hides a multitude of measurement capabilities, making it appreciated by specialists in many fields. The meter complies with the requirements specified in the EN 61557 standard.Features of Impedance Meter Sonel MZC-310S
Additional features
Reaching the areas unattainable to others
In the direct vicinity of transformers or in transformer stations, where the circuits are equipped with high current protection (fuse-links with the rating of several hundred amperes, motor circuit breakers), fault currents may reach several hundreds of kilo-amps. Measurement of fault loop impedance in such networks requires a high-current meter, which is capable of measuring ZS values at the level of single milliohms. Our patented technical solution, which uses components not available in the commercial offer (unique fault resistor), enables us to offer the meter with perfect performance in such demanding conditions.Unique features of the device
Since other commercially available fault loop impedance meters perform the measurements asymmetrically, using half-wave current, the Sonel MZC-310S introduces the transitional constant and DC constant, which does not always result in a linear behavior of the transformer during the tests. This affects the accuracy of the results. MZC-310S applies symmetrical current for measurements, which means that it uses the full wave - thanks to the advanced design of the measuring system and fault circuit.Applications of Impedance Meter Sonel MZC-310S
MZC-310S can be used for measurements in low voltage systems, where the prospective fault current may reach 55.7 kA (measured according to EN 61557). The lightweight and flexibility of the device make it perfect for tests and measurements in large and complex manufacturing plants.Product information | |
