The Rasnal VKP High Surge range is engineered for installations where standard surge protection capacity is not sufficient. Available in 480 kA and 560 kA maximum surge handling variants for both single-phase and three-phase AC systems, these devices are purpose-built for environments exposed to extreme lightning activity, repeated electrical surges, and critical digital loads that cannot afford disruption.
Rasnal VKP High Surge Digital Grounding Devices extend the proven VKP digital grounding platform to handle significantly higher surge energies. While the standard VKP-01 and VKP-03 models are rated at 120 kA and 240 kA respectively, the High Surge range pushes that capacity to 480 kA and 560 kA — making them the right choice when the site's lightning frequency, surge magnitude, or equipment sensitivity demands stronger margins of protection.
Like all Rasnal VKP devices, these models work on the energy conversion principle. They detect incoming surges and dissipate the energy through a low-impedance ground path rather than simply clamping voltage. This approach delivers equi-potential bonding across connected equipment, eliminates static charge buildup, and reduces leakage current — all without requiring a separate grounding rod.
Both phase configurations — single-phase (VKP-01 series) and three-phase (VKP-03 series) — are available within the High Surge range, making this a versatile solution across a wide range of industrial, telecom, and defence applications.
Higher surge handling capacity:
Maximum surge ratings of 480 kA and 560 kA at 8/20 µs for sites where standard capacity is not enough.
Single-phase and three-phase variants:
Available for both 1-phase (100–275 VAC) and 3-phase (380–415 VAC ±10%) electrical systems.
Energy conversion protection:
Works on the energy conversion principle — detects surges and converts them into heat energy dissipated through a low-impedance ground.
Equi-potential common grounding:
Bonds all connected equipment to a common ground reference, reducing inter-equipment voltage differences.
Leakage current reduction:
Provides a defined low-impedance path for leakage current, reducing the risk of interference and damage.
Static charge elimination:
Provides a low-impedance path for static charge dissipation, preventing charge accumulation on sensitive equipment.
No separate grounding rod required:
Does not require an additional grounding electrode in most installations.
Maintains Earth-to-Neutral voltage below 0 V: Keeps E-N voltage differential stable, supporting safe and accurate operation of sensitive electronics.
Enhanced battery life:
Stable power quality and reduced electrical stress contribute to improved battery life in connected systems.
Suitable for 24x7 operation:
Built for continuous duty in challenging environments including high temperature, vibration, and dust.
Certified and tested:
CE, ISO 9001, ISO 14001 certified. Tested in Indian Government IEC NABL Accredited Laboratory per IEC 61643-11, IEC 62301, and IEC 61000 series standards. Approved under Indian Military Standard JSS 55555-2012.
The VKP High Surge range is designed for environments where standard lightning surge protection is likely to be insufficient. This includes:
Sites located in high-lightning-density geographies — including tropical and coastal regions — where multi-stage and nearby direct lightning strikes are frequent and the standard VKP capacity is not enough to handle the cumulative surge load.
Tower-mounted and ground-level telecom equipment, radio systems, EPABX, CCTV, and data communication systems that operate continuously and cannot withstand downtime caused by surge damage.
Systems operating under Indian Military Standard JSS 55555-2012 test requirements, where the device's validation for shock, vibration, high and low temperature, damp heat, and sand-dust exposure makes it appropriate for defence infrastructure.
PLC systems, industrial control panels, motor drives, and automated systems in large facilities where a surge event can cascade through interconnected equipment on a common electrical network.
Locations where ground potential rise (GPR) effects are common, including isolated buildings, outdoor facilities, and mountain or rocky terrain where traditional low-resistance grounding is difficult to achieve.
Facilities that have already experienced equipment damage, component degradation, operation errors, or power supply unit failures due to surge events — where a higher-capacity protection device is the next logical step.
Data systems, communication infrastructure, and automated systems that must maintain continuous operation in harsh electrical environments, including those with poor power quality or unstable grid supply.
Facilities that have already experienced equipment damage, component degradation, operation errors, or power supply unit failures due to surge events — where a higher-capacity protection device is the next logical step.
No, VKP devices do not need a separate grounding rod for most installations. They create their own low-impedance path for surge dissipation, making them ideal for rocky or remote areas where traditional grounding rods are hard to install.
The VKP High Surge range is compatible with a wide range of digital and electronic systems, including:
EPABX and intercom systems
Network switches, routers, and data communication equipment
CCTV and DVR systems
PLC and industrial automation equipment
Telecom and RF equipment
Power supply units and UPS systems
Any AC/DC equipment connected to the electrical distribution panel
Yes, the VKP is designed for areas with low grounding resistance, such as rocky terrain or mountainous regions, providing effective protection without relying on a low-resistance soil grounding path.
The VKP High Surge devices operate across a temperature range of -40°C to +90°C, making them suitable for extreme cold and hot environments, including outdoor telecom towers, defence installations, and industrial plant environments.
Yes. Rasnal VKP devices are tested and approved under Indian Military Standard JSS 55555-2012. This covers Vibration, Shock, High and Low Temperature, Damp Heat, Dust, and Sand testing — validation requirements specifically relevant to defence and government infrastructure deployments.
