Earth Insulation Tester
Newly Developed Digital DC /AC Grounding / Earth Resistance Tester
Product introduction
BY2571 Earth Resistance Tester applies to power industry, post and telecommunications, railway,
communications, mining and other sectors to measure the grounding
resistance of the various devices, and the conductor resistance of
low resistance; this instrument can also measure soil resistivity
and ground voltage.
The instrument is a newly developed earth resistance tester, which
abandons the traditional way of generating electricity by hand
operation, uses advanced middle-large scale integrated circuits and
applies DC/AC transformation technology to combine three-terminal
measurement method and four-terminal measurement method into one
model.
Features
1. High-strength aluminum alloy shell body, the circuit equips with
phase locked loop and switched capacitor filter, based on which the
instrument play an effective role in shielding power frequency and
radio frequency interference.
2. DC/AC converter can transform DC current into AC low-frequency
constant current for the measurement.
3. Auxiliary grounding resistance are allowed to change in the
range of 0 ~ 2KΩ (RC), 0 ~ 40KΩ (RP), that will not affect
measurement results.
4. No need manual adjustment to zero, with three and a half bits
LCD display, the instrument can be used for measuring the grounding
resistance, low conductor resistance, soil resistivity and AC
voltage to ground.
5. If tested loop encounter failure, the screen displays "1"
indicating overflow, which consistent with conventional measurement
practices.
