High-Voltage Digital Insulation Meter - ZSJYB

ZSJYB Series High-Voltage Digital Insulation Meter

Summary:
ZSJYB Series High-Voltage Digital Insulation Meter can be widely applied in the transformer substation, power plant equipment maintenance field of high voltage electrical equipment, such as: transformers, reactors, capacitors, circuit breakers and other insulation resistance, absorption ratio, polarization index measurement.
Overview
1. ZSJYB series of high voltage digital insulation meter are all controlled by microcomputer, English operating system, can automatically measure the absorb ratio and polarization index; Continuous measurement and quick point measurement.
2. Large output power, when the short circuit current is more than 3mA ~ 5mA (according to different type), it will give loaded charge current.
3. Adopting new circuit design and digital filtering technology, which has great anti-jamming ability, suitable for complicated high-voltage field measurement.
4. Cell compatibility design, strong shock resistance, safety shell, easy to carry.
5. Built-in high-capacity 24V 1Ah Ni-MH rechargeable battery. Intelligent charging circuit; long life battery; specially designed battery box that convenient to replace field common battery for emergency test.
6. Protective functions about short circuit, overload, battery low capacity, etc. Text and sound reminds when breakdown occur.
