Safety test METRISO PRIME+

METRISO PRIME+

Digital high-voltage insulation tester, test voltage up to 5000V DC, voltage measurement to 1000V

Detect the residual voltage of the device under test, up to 1000V

Discharge the capacitive device under test

Capacitive devices under test, such as cables and coils, may be charged by the test voltage, which can be discharged by the meter. The item can show the voltage value drop process.

Measurement according to EN61557, DIN VDE 0413

Test voltage is 100, 250, 500 or 1000V, rated current is 1Ma

High insulation performance measuring cable

For safety reasons, the high insulation performance measuring cable is fixedly connected to the tester sampling to avoid the risk of inadvertently interrupting the cable connection.

Measuring Polarization Index (PI)

Electrical machines are usually subjected to polarization index testing. The temperature testing angle is an extension of the insulation resistance test. The DC measurement provided by METRISOPRIME+, the voltage can last for ten minutes in the insulation test. The measurement results were recorded after one minute of testing and one measurement was recorded ten minutes later. If the measured value at ten minutes is greater than the measured value at one minute, say

The insulation is good. The ratio of the two measurements is the polarization index. During the insulation test, the carrier inside the chargeable material is aligned due to the long measurement voltage, resulting in polarization. The polarization index indicates whether the internal carriers of the charged insulating material can also move, that is, whether they can also be polarized, that is, the polarization index indicates the state of the insulating property.
