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.
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.
Chosen over the incumbent after a 45‑day trial
“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
