Electrical Safety SolutionsWarn before contact. Protect at contact.
Non-contact voltage detectors for the worker, the work zone and the vehicle, plus dielectric fall protection and Class E head protection. Built for utilities, telecom and industrial crews who work beside live conductors every day.
Start with how your people work
Most sites use more than one: a wearable for every worker, a sentry where the hazard is fixed, and the right PPE underneath.
A crew in one work zone
Stand a sentry at the edge of the job, up to 3.1 m high, heard by everyone. VoltRadar™ →
TripodVehicles near lines
Fit once; it arms with the ignition and alerts the driver in the cab. ClearVolt™ →
VehicleClimbing electrical structures
Non-conductive harness with a detector on the shoulder. Kavach™ →

Layers of protection, not a single device
Isolate and earth
Permit to work, isolation, contact testing and earthing remain the first line of defence. Jarsh detectors do not replace them.
Warn before contact
Non-contact detectors (SmartVolt, VoltRadar, ClearVolt, Kavach) sound the alarm when someone, or something, gets close to a live line.
Protect at contact
Dielectric PPE (the Kavach harness and the Class E JSH-01 helmet) keeps conductive paths away from the body.
Prove it
Data sheets, test certificates and field case studies support your audits and tenders.

“The SmartVolt fundamentally changed how our Electrical Maintenance Engineer teams approach preliminary checks. We no longer had to risk contact or rely on complicated procedures for a simple ‘live or dead’ confirmation.”Network Maintenance Engineer, leading Indian internet service provider, Hyderabad
