Brief Introduction
MEWOI9000G/9000GB Current/Leakage Monitoring Recorder is well
designed and manufactured for online measurement, monitoring and recording of
AC leakage / current. It is composed of a tester, monitoring software, current
clamp and communication cable, etc. This instrument has been widely applied in
many fields, such as electrical power, telecommunication, meteorology, railway, oil
fields, construction, metering, research agencies, universities, mines and
enterprises.
Both Chinese and English MMI is built in the instrument. Therefore, it is
suitable for use by engineers and technicians of different counties. The instrument
has a large LCD display with blue background and a large storage space. 4200
sets of data can be stored in the instrument. In addition, the instrument can
automatically store data at an interval, which is adjustable from 1 to 60 min.
MEWOI leakage/current monitor software provides online and real-time
monitoring and historical data inquiry. With the software developed by our
technical department, the instrument can display leakage current dynamically,
display current waveform, maximum value, minimum value and average value.
The users can preset the alarm limit. The instrument will generate an alarm when
the measured current exceeds the limit. In addition, the users can read, inquire,
store, analyze, process, sequence historical data and generate and print a fitting
curve and report.
The flexible current clamp, using the advanced Rockwell coil (or Rogowski
coil) technology, is a circular coil that is uniformly twisted on non-ferromagnetic
materials. There is no hysteresis effect, almost zero phase error, no magnetic
saturation, high linearity and strong anti-interference ability. The output signal is
the differential of the current to the time. By integrating the output voltage signal,
the input current can be reduced and the current range can be measured from mA
to 20000A. The flexible current clamp coil has no bare metal conductor,
non-contact measurement, safe and fast, it is small in size, light in weight, delicate
in appearance, suitable for a place with narrow environment and dense line. The
user can customize the length of coil according to the requirement.
