10A DC Resistance Tester
For Digital Automatic Transformer Winding Resistance Testing
Product Description
XHZ1010 10A Transformer DC winding resistance tester
Transformer DC resistance is a must-test item in transformer
manufacturing for semi-finished products, finished products,
factory test, installation, overhaul, after changing the tap
changer, handover test and preventive test in the power sector. You
can check the welding quality of the winding joints and whether the
windings have short-circuits between turns. You can check whether
the contact of each position of the voltage tap switch is good,
whether the actual position of the tap changer matches the
indicated position, and whether the lead wire is broken. Whether
there is stock breakage, etc.In order to meet the needs of rapid measurement of transformer DC
resistance, the XHZ1010 transformer DC resistance tester developed
by our company. The instrument adopts a brand-new power supply
technology, which has the characteristics of small size, light
weight, large output current, good repeatability, strong
anti-interference ability, and perfect protection functions.
The whole machine is controlled by a high-speed single-chip
microcomputer, with a high degree of automation, with automatic
discharge and discharge alarm functions. The transformer winding dc
resistance tester has high test accuracy and easy operation, which
can realize rapid measurement of transformer direct resistance.
Your logo can be put on the panel of the equipment.Each equipment
got a series number.
Functional characteristics
1. The instrument can be fully controlled through dedicated
software using a mobile phone, and the test data is stored in a
fixed format on the phone, making it easy to query data at any
time.
2. The maximum output voltage of the instrument is 24V, which
facilitates the selection of a larger test current for high
resistance values and improves the testing speed.
3. The instrument adopts a new power supply technology, with
multiple current ranges and a wide measurement range. It can
automatically select the current according to the load and is
suitable for DC resistance measurement of small and medium-sized
transformers and voltage transformers.
4. It has multiple protection functions such as back electromotive
force impact, wire breakage and power outage during testing, power
overheating, etc. It can reliably protect the impact of back
electromotive force on the instrument and synchronously sound an
alarm.
5. With any temperature conversion function made of copper and
aluminum materials, touch to input any winding temperature and
conversion temperature.
6. Intelligent power management technology ensures that the
instrument operates at the minimum power state, effectively saving
energy and reducing heat generation.
7. Seven inch high brightness touch color LCD, clear display under
strong light, full touch screen operation, and free switching
between Chinese and English.
8. The instrument comes with a perpetual calendar clock and power
down storage, which can store 1000 sets of test data and can be
viewed at any time.
9. The instrument has Bluetooth communication, RS232 communication,
and USB interface for computer communication and USB data storage.
10. Equipped with a panel mounted micro printer, it can print
measurement results in English.
