Anti Power Down Megger Insulation Tester Insulation Test Meter Anti
Interference Ability
I. Overview
Digital Insulation resistance tester embedded real-time industrial
microcomputer operating system, ultra-thin wire-shaped sheets
header with the perfect combination of dot matrix liquid crystal
display, the instrument is with a variety of voltage output level
(2500V,5000V,10000V), high capacity, strong anti-interference, the
pointer and digital synchronous display, AC-DC dual-use, simple
operation, automatic calculation of various insulation index
(absorption ratio, polarization index), all measured
characteristics with the anti-power-down function . It is suitable
for measuring high capacity transformers, transformers, generators,
high voltage electric motors, power capacitors, power cables, surge
arresters and other ideal insulation resistance test equipment.
II. Features
1. There are a variety of output voltages HY2303 (2500V,
5000V,10000V), resistance range measuring range up to 0 ~ 400GΩ,
resistance measuring range can be automatically converted, and have
the corresponding instructions.
2. Insulation resistance simultaneously displayed in two ways:
change range of insulation resistance can be easily observed by
Analog pointer; Digital Display has measurement accurate results.
3. Embedded and real-time operation of industrial microcomputer
software system. High degree of automation, anti-interference
ability, equipment can be automatically calculated absorption ratio
and the polarization index, without human intervention.
4. User friendly, all measurement results with anti-power-down
function, can store 19 consecutive measurements.
5. Produces high-pressure instrument, there are tone output.
6. Built-in residual high voltage discharge circuit, testing is
completed on the device under test can be automatically let go of
the residual pressure.
7. AC and DC, configuration rechargeable battery and AC adapter.
8. Meter with Portable design for easy field operation.
9. High voltage short circuit current ≥ 1mA, is the measurement of
large transformers, transformers, generators, high voltage electric
motors, power capacitors, power cables, surge arresters and other
ideal insulation resistance test equipment.
