This flagship GW Instek GPT-15003 500VA hi-pot tester is the first in the world to comply with IEC 61010-2-034. It is able to perform AC withstanding, DC withstanding, insulation resistance, and ground continuity tests. This Hi-pot tester is a good choice due to its high accuracy/resolution and a maximum test voltage of 5 kV. Additionally, the GPT-15000 contains a sweep and tabular automatic test as well as a statistics function. The GPT-15000 series has a test capacity of 500VA and a capacitive load testing capability up to 47 μF. The testers are designed for ease of use, the high-resolution LCD display clearly shows which settings have been chosen and whether the test object meets the set requirements. The GPT-15000 can be connected to a computer via a USB host port, RS-232C for remote control and optionally GPIB in order to be able to store data.
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. The testers offer the possibility to save 100 default settings. Of these, 16 can be performed automatically at the touch of a button.
For a Hi-pot tester with the same specifications but lower maximum rated load you can look at the GPT-12000 series. Or a hi-pot tester with fewer capabilites such as no usb storage, No GC function, smaller screen, and no data memory, you can look at the GPT-9900 or GPT-9800 series.
For a high voltage adapter box, you can look at the GHT-117 or the GHT-118.
The difference between the models in the GPT-15000 series is explained in the table below.
