MOEORW-7705 Insulation resistance testing device for transmission lines (5kV) Send email to us

Applications

Measurement of absorption ratio DAR:
1.Select the measurement duration of more than 1 minute
2.Select the appropriate voltage and start
3.The instrument automatically records the resistance values of 15S and 60S, and calculates the absorption ratio after 60 seconds.
The calculation method absorption ratio: DAR= R60/R15;
Measurement of polarization index PI:
1.Select the measurement duration of more than 10
2.Select the appropriate voltage and start.
3.The instrument automatically records the resistance values of 15S, 60S and 600S and calculates the polarization index after 600 seconds.
The calculation method of the polarization index: PI= R600/R60

Features

● Insulation resistance testing device for transmission lines, with 5 ranges: 250V, 500V, 100V, 2500V, 5000V, the test can reach up to 5 TΩ.
● Design strictly according to safety
● Insulation resistance range 5 TΩ@5kV
● Short-circuit current is adjustable, up to a maximum of 5 mA (can be to produce a product with a short-circuit current of up to 10 mA).
● Automatically display the test values of the polarization index (PI), absorption ratio (DAR), and can test leakage current and capacitance.
● Excellent anti-interference performance, the instrument still guarantees test accuracy when the interference current reaches2 mA.
● Capacitive test pieces are quickly discharged, and there is no need for manual discharge when testing cables, the instrument automatically and quickly discharges.
 2 power supply modes: powered by lithium-ion batteries, the battery life can reach 6 hours (5000V@100M test resistance).
   It can also be charged while in use. In the event of a power outage, it can automatically switch from AC power supply to battery power supply.
● Full English, English prompt operation, simple and clear, and can display the analog column of insulation resistance.
● Digital filtering function, use the filtering function to reduce the impact when the display deviates due to external influence.
● Complete protection functions, and spare fuse fuse prompt function.
