Portable measuring equipment for grid analysis
April 6, 2010
TDK-EPC, a group company of the TDK Corporation, presents a complete measurement
system from EPCOS for the measurement and storage of electrical parameters in 3-phase
low voltage grids. The MC7000-3 is designed for measuring voltages in the ranges from
3 x 30 V AC to 440 V AC (L-N) and 3 x 50 V AC to 690 V AC (L-L) at 50 Hz or 60 Hz.
Currents of up to 3000 A can be recorded with the aid of a clamp-on ammeter.
In addition to measuring voltage, current and line frequency, the MC7000-3 is designed
especially to determine the reactive, apparent and real power as well as the power factor.
It also records the voltage and current harmonics.
All data and readings are shown on a 128 x 64-pixel display either numerically or graphically.
The unit also features an oscilloscope function. The results can be saved on an SD memory
card and output in Excel format or printed out. The Windows-based software allows a wide
range of functions to be programmed and the data to be evaluated graphically and numerically. The measured results are assigned a date stamp for superior transparency. The meter
also calculates the required corrective power for a given cos phi. The results can also be
simulated under different basic conditions. This makes the MC7000-3 eminently suitable for
very simple on-site dimensioning of customer-specific PFC installations or evaluating the
performance of existing systems.
The scope of delivery of the MC7000-3 comprises the Windows software and an SD memory
card (1 GB) as well as a power adapter (110 V AC to 230 V AC), various test leads and a
rugged plastic carrying case. The standard menu languages are English, German, Russian,
Spanish and Turkish.
----Glossary
 Reactive power: This occurs whenever the phase angle between the current and voltage is shifted.
It is caused by inductive loads, such as electric motors and transformers. Reactive power has no
use, but must be generated by power plants.
 Power factor correction: Reactive power can be almost completely corrected through the use of
PFC capacitors. This measure reduces energy costs and protects the environment.
Main applications
 Analysis of three-phase low-voltage power grids and calculation of the required corrective power.
