15KV Digital Voltage Adustable Megohmmeter Megger
I.Introduction
For safety, before using the instrument must be well
earthed,because the measured target connecting to high voltage
power exists power frequency leakage.
Once high voltage being started, do not use manual discharge method
to check the instrument. After test, please wait the instrument
complete automatic discharge and automatically return to zero, then
manual discharge can be operated. That is because electrical pulse
caused by short-circuit discharge will damage the insulation life
of the measured object; if the pulse fleeing into the instrument,it
will also damage the integrated circuit inside the instrument.
The instrument is designed for HV substations and power plants to
test the characteristic of large HV transformer, electric machines
and appliances, remote power cable or buried cable and other
electrical insulation resistance in strong interference
environment.
It also can be widely used for testing characteristics of insulation resistance in other area.
II. Main feature
1. With strong anti-electric field interference ability up to 2mA
(50Hz), it is suitable for 500kV substation without dismantling
wire to test insulation resistance of 500kV large-scale
transformer.
2. The short-circuit current of test power> 5mA, maximum up to
15mA. Be suitable for testing high capacity and high inductance.
3. Wide resistance range from 0.5MΩ ~ 1999GΩ. With high-resolution,
having accurate readings.
4. Wide voltage range: 0.25kV, 0.5kV, 1kV, 2.5kV, 5kV, 10kV, 15
kV/20kV, you can smoothly adjust voltage from 0V to the desired
value.
5. With timekeeping function, remind users to record, and analyze
absorptance and polarization index of measured target.

Calibration voltage of MΩ range is 0.5kV; Calibration voltage of GΩ range is 2.5kV
| Anti-electric field interference ability | 2mA(50Hz) | |
| Timekeeping and alarm function | maximum value of stopwatch is 19 minutes and 59 seconds. 20 minutes for a cycle. The stopwatch will tell the time at these time points: 15 seconds, 60 seconds and every 60 seconds. When telling time, resistance readings hold for 5 seconds. If the measured resistance is below the lower limit of range, the reading is invalid and the instrument will continuously sound to give an alarm | |
| Display | three and a half bits LCD digital meter (three), respectively show test voltage, test resistance, test time | |
| Power supply | 10×1.2Vbattery(2000mAh Ni-MH rechargeable battery), total DC12V power supply AC: 220V (50/60Hz) | |
