Capacitive voltage indicator, also called Capacitive Voltage Detecting System, is an ideal solution for detecting the presence and absence of voltage in medium-voltage switchgear. Read our blogpost to know what is voltage indicator. Our capacitive voltage indicator is IEC 62271-213, IEC61243-5, and IEC62271-206 listed, waterproof and dustproof with IP54 protection standard. IEC standard is a preferred consideration for choosing the capacitive voltage indicator in mv switchgear. If you need help selecting the right IEC Voltage Detecting System, please feel free to contact us, we will be happy to assist you.
Since 2010, Blue Jay has delivered tailored, high-quality solutions for industrial electrical automation. Our experienced engineers specialize in metering and protection products, such as our reliable capacitive voltage indicators. We are committed to innovation and uncompromising quality, ensuring all our products comply with IEC standards.
IEC Standard Compliant for manufacturing high quality capacitive Voltage indicator
Easy for installation and maintenance free. Reducing your cost and improve effiency.
OEM & ODM service: customized your voltage indicator with relay or without relay
Size: Different M.V. cubicles have different spaces for electrical components so your switchgear needs different sizes of voltage-detecting system. Blue Jay’s selection of capacitive voltage indicators includes a wide variety of sizes such as 32*55mm,92*44mm, and 100*70mm.
Relay output option: Your application may require a voltage-detecting system with a control relay. The control relay is for voltage presence and phase absence monitoring. Blue Jay can provide the voltage-detecting system with one or two control relays. Besides, we also provide a voltage presence indicating system without relays.
HR & LRM Interface option: our capacitive voltage indicator has a low resistance modified (LRM) interface or HR interface. It makes you easily connect the short-circuit indicator for voltage measurement.
Two-stage indication/Self-test function: Most of our voltage-detecting systems are two-stage indication, self-test function. But some of them are without these functions.
Wide-range 3kV- 40.5kV: Our capacitive voltage indicator detects Check absence of voltage from 3 kV up to 40.5KV, which is an important part of the precautionary measures in the operation of medium-voltage switchgear and ensures the safety of operating personnel.
