China Mutual Inductor Secondary Voltage Step-Down Load Test Set

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:
1.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.
2.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.
3.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.
4.Large screen liquid crystal display, the data can be stored and browsed when power off, can communicate data with the computer online.
5.The electronic principle circuit and DSP technology are adopted to make the test stable and anti-interference ability strong.
6.Use engineering plastic case, strong and durable, and ensure the safety of test personnel and system.
7.It can realize three-phase three-wire, three-phase four-wire and single-phase full-automatic measurement.
8.Working hours can be as long as 24 hours (longest).
9.With a lightweight charger, it is easy to measure, and can be measured with external charger when the battery is low.
10.The instrument is small in size and light in weight.
11.The instrument has the active switching function of the range to ensure the test precision.
12.Can store 480 sets of measurement data, which can be maintained for 10 years after power off.
13.Large screen display with RS-232 communication interface.
