Strong Capability Ant Interfere Ground Resistance Tester With PC
Data Processing
1. Product Name:
Grounding resistance tester HYDW-5A
2. Equipment Description:
Model HYDW-5A, Grounding resistance tester for different frequency
ground grid, is the high precision measuring instrument that is
used in measuring the ground resistance and testing related
parameters in substations and other situations. The outstanding
advantages of this instrument are small in size, light in weight,
portable and precise and capability of anti-interfere is strong.
3. Main characteristics:
Being simple to operate, Model HYDW-5A is equipped with a full
touch LCD display, which enables the users to operate it without
additional training, because every procedures of the operation is
vivid and clear with the full graphical operating interface. The
whole process of measurement can be completed by simple touch, so
it is the most ideal intelligent measuring equipment at present.
Strong capability of anti-interfere. The built-in frequency
conversion power module can provide the output power for
measurement with the frequency varying from 45Hz to 55Hz. It also
adopts the high-end digital filtering technology to avoid various
power-line interference signals, which makes sure the instrument
can give accurate, precise and reliable measurement.
Accurate and fast. Instrument has adopted the professional DPS high
speed digital processor as its operation core, which tremendously
improved its processing capacity on the premise of ensure measured
data accurate.
With the strong support of high performance processing inner core,
the instrument can achieve a series of complex and difficult
process quickly and automatically, including the current output,
voltage acquisition and frequency transformation during the whole
measuring process. What’s more, it can
automatically judge the impedance of the current loop and adjust
the output value of the different frequency power supply
accordingly (the rated output is 5A ) without any intervention from
people. And the content of the testing includes the ground
impedance of the ground grid Z, the pure resistance component R and
the pure inductance component X.
The instrument is equipped with calendar chip and mass storage
device, which can store the result according to the time order. So
it is convenient for the users to check the record and print it.
The data measured by the instrument can be derived by USB flash
disk and it is easy to check and manage relevant data on the
computers.
