Mutual Inductor Secondary Voltage Step-down and Load Electrical
Test Equipment
Production Description:
HZYF-406 mutual inductor secondary voltage step-down and load
tester, usually measure the mutual inductor in the current mutual
inductor error test, according to specified current load box and
voltage load box on nameplate.What is the actual secondary load
during the mutual inductor operation? Is it the specified value on
the mutual inductor nameplate? What is the error of the mutual
inductor under the actual secondary load? In order to solve the
above problems, it is very important to actually test the secondary
load of the mutual inductor. At the same time, it is a important
problem that how to sample the current signal during the actual
second load test. During test secondary load on site , cut off
power and current circuit is neither convenient nor safe. Our
products are used to sample the line current by the clamp current
transformer (clamp meter), which is convenient for users to use.
Other company adopt PT voltage as the instrument working power,
this is not very safe. Our instrument adopts large capacity lithium
battery as a power source, it can both ensure the security of
system and provide pure power supply, avoid the power interference
on site, guarantee the measurement accuracy.
Product Features:
◆Secondary load test, use the clip-on ammeter sampling current, do
not need to disconnect the secondary loop, can achieve online
measurement without power off, automatic switching range: switching
to a different location according to different measuring value of
the test object during test process, guarantee the accuracy of
measurement and display digits.
◆use a large capacity of 7.2V1 1 Ah lithium battery as power
supply, no impact on the test circuit, and avoid system occurs
protection situation. Meanwhile, it is used when no power source on
site.
◆Extremely broad secondary working current/voltage range, in 50mA
working current, can distinguish the resistance and reactance of
1mΩ, can test the secondary rated current is 5A S-class current
mutual inductor online actual load; under the working voltage of
5V, it can distinguish 0.001mS electrical conduction and sodium.
◆Large screen liquid crystal display, the data can be stored and
browsed when power off, can communicate data with the computer
online.
◆The electronic principle circuit and DSP technology are adopted to
make the test stable and anti-interference ability strong.
◆Use engineering plastic case, strong and durable, and ensure the
safety of test personnel and system.
◆It can realize three-phase three-wire, three-phase four-wire and
single-phase full-automatic measurement.
◆Working hours can be as long as 24 hours (longest).
◆With a lightweight charger, it is easy to measure, and can be
measured with external charger when the battery is low.
◆The instrument is small in size and light in weight.
◆The instrument has the active switching function of the range to
ensure the test precision.
◆Can store 480 sets of measurement data, which can be maintained
for 10 years after power off.
◆Large screen display with RS-232 communication interface.
Quality Guarantee: One year quality guarantee after shipment.
