Product Description
AC hipot testing is the effective and direct way to test insulation strength for electrical equipment, apparatus or machines. It checks dangerous flaws which assure electrical equipment continuous working.
Typical applications include testing of transformers, switchgear, cables, capacitors, aerial motors platforms, hot sticks bucket bricks, vacuum bottles and other related equipment like vacuum interrupters, blankets, ropes, gloves, hydraulics hose, instruments transformers generators.
Features
-
Enhanced 320×240 LCD Display (Daylight visible).
-
Built-in high speed thermal printer.
-
Multi-channel measurement, with high precision sensor and high performance 14digit AD acquisition chip.
-
Full keyboard operation, manual mode or automatic mode to be selected.
-
Display HV voltage/current, LV voltage/current, time and withstand results.
-
With over-voltage, over-current protection. Output voltage, upper limit of HV current and LV current, timing can be set at any time.
-
During automatic testing, voltage increasing or decreasing can be paused, which is convenient to watch the test object.
-
Zero start function. Testing can be proceed after voltage is back to zero.
-
When the voltage is arrived at setting value, timing starts automatically. After timing, the voltage is back to zero automatically.
-
When the value is over setting HV current or LV current, the voltage output will be cut off automatically and voltage is back to zero. It will also alarm with sound and light.
-
In testing process, the testing can be canceled. Emergency stop button is designed for any emergency situation.
-
With anti-interference function.
