The GPT-9800 series Hi-pot testers from GW Instek are high quality Hi-pot testers at an attractive price. The GPT-9803 is able to perform AC & DC withstanding and insulation resistance tests. Many features and a maximum test voltage of 5 kV make these testers a good choice.

The testers are designed for ease of use, the high resolution dot LCD display clearly shows which settings have been chosen, and whether the test object meets the set requirements. The devices meet the test requirements of IEC, EN, UL, CSA and CE.

The GPT-9800 can be connected to a computer via USB, RS-232C and optionally GPIB for remote control and data logging.

When working with high voltages such as 5 kV, it is important that no safety problems occur. The testers are designed to minimize the chance of this happening, so when the test is completed or a dangerous situation occurs they switch off the voltage within 150 µ's of the output and the voltage across the DUT is discharged within 200 ms.

The testers offer the possibility to save 100 default settings. Of these, 16 can be performed automatically at the touch of a button.


Hi-pot (DC/AC withstanding)
Aim: To prevent users of a product from receiving an electrical shock, for example due to a failure of the electrical insulation.
Method: By measuring the amount of current leaking between the high voltage part and the "safe" low voltage part while using the product in high-voltage mode, one can measure whether dangerous situations may occur.

Isolation test
Aim: To test the quality of the insulation
Method: Alike to the Hi-pot test, measure how much current is leaking from the high-voltage part to the low-voltage part of the circuit.

Ground Bond
Aim: To test if any switching conductive parts and their ground are well connected.
Method: Check if there is an electric path between conductive metals and the ground of the power supply. The quality of the path is checked.

Arc detection
Aim: To expose potential problems such as loose screws or poor insulation.
Method: Measure the duration of the current peak that is caused when a drastic change in the supply voltage occurs. This is usually done during a Hi-pot measurement.
