GM Series Adjustable Insulation Resistance Tester

1. Product Introduction

GM Series adjustable insulation resistance tester is designed and developed for testing the insulation resistance of large type of high voltage transformer motor remote power cables or underground cable and others under strong interference in the high voltage substations or power plants. It can also be used for measuring electrical insulation resistance in broad areas.

2. Characteristics and Functions:

(1) The instrument has very strong electric field induction interference resistance can be up to 2mA (50Hz) it can adapt to the 500000 V substation site can test the insulation resistance of 500000V large transformer without disconnection.

(2) Test the short circuit current of power is greater than 5mA the maximum is 15mA. Adapt to high capacity and large inductance test.

(3) Wide range of resistance measurement from 0.5MΩ to 2000GΩ with accurate reading and high resolution.

(4) Wide range of voltage measurement 0.25kV 0.5kV 1kV 2.5kV 5kV 10kV 15kV can be optional it can also continuous adjustment from 0V smoothly to the required voltage.

(5) With time function to remind the users to record and analysis the absorption ratio and polarization index of the measured object.

1. Product Specifications:

Model	Measuring voltage	Accuracy of voltage	Short circuit current
GM-5kV	0～0.25 0.5 1 2.5 5kV	±(5%+10V)	＞5mA
GM-10kV	0.5 1 2.5 5 10kV	±(5%+10V)	＞5mA
GM-15kV	1 2.5 5 10 15kV	±(5%+10V)	＞5mA
GM-20kV	0.5 1 2.5 5 10 20kV	±(5%+10V)	＞5mA

2. Measuring Range and Accuracy:

Measuring range (limit)	Resistance measurement range	Accuracy
20MΩ/500V	0.5～19.99MΩ	±(5%+5字)
200MΩ/1000V	5.0～199.9MΩ	±(5%+5字)
2GΩ	0.05～1.999GΩ	±(5%+5字)
20GΩ	0.5～19.99GΩ	±(5%+5字)
200GΩ/10kV 5kV	50～199.9GΩ	±(10%+10字)
2000GΩ/20kV 15kV	50～1999GΩ	±(20%+10字)

Standard rated voltage of GΩ range is 2.5kV.
3. Anti-electric interference: 2mA (50Hz)
4. The function of time and alarm:
The stopwatch shows a maximum value of 19 minutes and 59 seconds 20 minutes a cycle. The alarm time is about 15 seconds per minute or 60 seconds the sound is short the resistance reading keep 5 seconds when the measured resistance is lower than the limit of the range the reading is invalid it can continuously alarm.
5. Display: three and half digit three LCD digital meter respectively show the test voltage resistance time.
6. Power supply: enclosed 10 pieces of 1.2V/2000mAh NiMH rechargeable battery DC12V. With AC 220V (50/ 60HZ) access to the battery charging or float charging.
7. Operating environment:
Temperature: 0℃ ~ 40℃; Relative humidity: 20% ~ 90% RH
8. Size: 315mm×240mm×155mm
9. Weight: 5kg
