The instrument is suitable for the detection of live or blackout of zinc oxide surge arresters of various voltage levels, so as to discover the dangerous defects such as internal insulation moisture and aging of the valve plate in time.
The instrument is simple in operation and easy to use. The whole process of measurement is controlled by a single-chip microcomputer and can measure the full current, resistive current and its harmonics, power frequency voltage, active power and phase difference of the zinc oxide arrester.
The large screen shows the true waveform of voltage and current.
The instrument uses digital waveform analysis technology and adopts software anti-jamming methods such as harmonic analysis and digital filtering to make the measurement result accurate and stable. The fundamental wave and the 3rd to 7th harmonics content can be accurately analyzed, and the influence of interphase interference can be overcome. Measure the resistive current of the edge arrester.
The instrument uses a unique high-speed magnetically isolated digital sensor to directly acquire the input voltage and current signals, ensuring the reliability and safety of the data.
The instrument is equipped with a high-speed panel printer, rechargeable battery, and the test personnel are very convenient to use in the field.

Features
The machine is used to process untwisted chinlon into high stretch fiber.At the same time, it can make spandex and stretch chinlon to be air covering. Through the special intermingle nozzle to achieve chinlon/polyester air covering in one step. The machine is the most advanced, low energy consumption,but high production.
Performance
1.Three rollers named machine D1,D2,D2.2,all adopt the godet mechanism. The godet is controlled by the micro-motors. It control the fiber will and ensure the stretching.
2.The machine`s two sides (A-B) running relatively independent, both adopt energy-saving motor instead of belt,the process parameters can be set separately. Two sides could process different productions.
3.The specially energy-saving nozzle can save air and power.
4.Two-step D2 roller structure improve the node uniformity and fastness of the nylon spandex.
5.The special fiber structure is adopted to improve the efficiency of fiber processing.
6.The adjustable spandex universal support is adopted to ensure the spandex feeding well during high speed running.
7.Electric structure ensures convenient and quick threading.(Optional)
8.Machine`s deformation heater adopts biphenyl air heating.The temperature precision is exact to ±1 ℃ assure every spindle`s temperature to be same.This is beneficial for dying.
9.Excellent machine structure reliable drive system and low noise. It is easy for process adjustment, and maintained by single spindle to improve productivity.
