    • Inductive high-voltage electroscope high- voltage test pencil high- voltage test pencil high-voltage sensor 
    Product model: 276SHD 
    high-voltage electroscope with telescopic high-voltage test rod 
    This model 276SHD high-voltage electroscope is mainly used to detect the presence of voltage in the AC cable. 
    Retractable insulation rods allow high voltage lines to be detected at safe voltage distances. The instrument is small, lightweight and easy to hold. 
    The high voltage electroscope is also used for voltage detection of ordinary low voltage lines. 
    The instrument undergoes strict insulation and leakage testing to ensure the personal safety of the user. 
    High-voltage electroscopes are the right assistants for engineering installation and maintenance personnel in the power sector. 
    Instrument leather case with belt buckle that can be worn into the belt for easy carrying
     
    product features:

    ◇ Retractable, small and lightweight, easy to carry.
    Length: from 230mm to 880mm
    Weight: about 140g
    Easy to operate and easy to carry.

    ◇High pressure detection (inductive) 
    For high-voltage line voltage detection in the extended state (1KV-24KV, the higher the voltage, the farther the distance), whether the cable is bare or sheathed (non-metallic shield) can be measured. 

    ◇ medium pressure detection (inductive or contact type) 
    1KV-3KV communication, customers can choose contact or inductive measurement according to their needs or actual conditions on site. 

    Low-voltage detection (contact type) 
    Hold the indication part of the high-voltage electroscope detection head for low-voltage circuit voltage detection (80V-3KV). Before use, the measurement accuracy can be guaranteed by testing the 220V AC power socket.

    ◇ indicator light and buzzer
    When the voltage is detected, the red high-brightness LED indicator flashes intermittently, and at the same time, the buzzer emits intermittent sound, which can be easily recognized during daytime and noise.

    Waterproof
    The probe is waterproof and designed to be fastened and will not affect the instrument due to dust, dirt and rain.

    ◇ Compliance with standards
    EN61010-1EN50081-1EN55082-1EN55022EN61000-4-2EN61000-4-3
     

    Performance and technical parameters:

    ◇ test voltage range
    High voltage detection: 1KV ~ 24KV AC... non-contact
    Medium voltage detection: 1KV ~ 3KV AC... can be contact or non-contact
    Low-voltage detection: 80V ~ 3KV AC... Contact

    被 High voltage electroscope's measured voltage frequency: 50Hz/60Hz

    ◇Operational test (initial voltage)
    1. When stretching, hold the sliding part. Will sense the contact voltage: 25 0V AC ± 50V, LED indicator and buzzer will work.
    2. When retracting, hold the marked part. Will sense the contact voltage: 80V AC or low, the LED indicator and buzzer will work.

    ◇High-voltage electroscope operation distance
    At 24kV / ø3mm (voltage to ground) ... about 20cm
    At 6.6kV/ø3mm (voltage to ground)... about 3cm
    At 3.3kV/ø3mm (voltage to ground)... about 1cm

    ◇ high voltage electroscope insulation strength
    1. Between the inductive sliding parts: 50kV AC, 1min minutes (the detector has been stretched).
    2. Between the sensing parts: 4kV AC, 1min minutes.
     
    ◇High-voltage electroscope structure
    Waterproof (detecting head waterproof)

    ◇ high-voltage electroscope insulation performance test
    It has been verified by a high voltage insulation tester.
    1. Between the inductive sliding parts: 1kV (the detector has been stretched). The insulation resistance exceeds 2000MΩ.
    2. Between the sensing parts: 1kV. The insulation resistance exceeds 2000MΩ.

    ◇High-voltage electroscope leakage current test
    It has been verified by a leakage current tester.
    1. Between the inductive sliding parts: 50kV AC, 1min minutes (the detector has been stretched). Leakage current is less than 100μA
    2. Between the sensing parts: 4kV AC, 1min minutes. The leakage current is less than 100μA.

    ◇High-voltage electroscope operating temperature range
