Product Description

High Voltage Transformer Insulation Resistance Tester GD3126A










General Information
 
This device can test insulation resistance (such as transformer, switchgear, lead, motor) of different modules in one system, to insulate and repair failure components.
It is important to ensure products quality and security of person and equipments during operation by insulation test of checking test object to ground or adjacent conductors insulation.

Before power on the system, using insulation test to verify if it is good to improve system performance. Insulation test is to find manufacturing process problems and equipment fault which can not be found before failure happened.In EU,this test is compulsory,even to civil system.
 
 
Features 

1. With strong anti-interference ability.
2. Short-circuit current of test power is from 5-15mA, suitable for big capacity and big inductance test.
3. Broad testing range of resistance, from 0.5MΩ-200GΩ, more accurate reading and high resolution.
4. The voltage can be also adjusted from 0V to required voltage.
5. With timing function, convenient for recording absorption ratio and polarization index.
