What Products Are Included in the HV Hipot Accessory Series?
The HV Hipot Accessory Series includes specialized sensors, test rods, and handheld meters for high-voltage diagnostics. It covers ground resistance sensors, cable fault detection rods, HV divider probes, and portable meters for insulation, continuity, and battery testing.
HV Hipot’s Accessory Series is engineered to extend the functionality of its core high-voltage test instruments. The lineup is segmented into three main categories:
-
Sensors: High-precision current and voltage sensors for relay protection testers, partial discharge detectors, and power quality analyzers. These include Rogowski coils, Hall-effect current sensors, and capacitive voltage dividers rated up to 550 kV.
-
Test Rods: Ground resistance test rods (copper-clad steel, 0.6–1.2 m), cable fault pinpointing rods with acoustic-magnetic synchronization, and HV probe rods with integrated shielding for field safety.
-
Handheld Meters: Portable DC resistance testers, insulation resistance meters (up to 10 kV output), ground resistance testers (2-wire/3-wire/4-wire), and battery impedance analyzers.
In our Shanghai factory, we’ve observed that over 60% of OEM orders include at least two accessory types bundled with main units—most commonly ground rods paired with earth testers, and HV probes with insulation testers. This reflects real-world field workflows where technicians need immediate, plug-and-read capability without secondary calibration.
What Are the Key Specifications and Safety Ratings?
HV Hipot accessories meet IEC 61010, CE, and ISO9001 standards, with IP54–IP67 ingress protection and CAT IV 600 V safety ratings. Sensors support 0.1%–0.5% accuracy; rods withstand 50 kV impulse; meters offer 10,000+ data logging capacity.
Safety and precision are non-negotiable in high-voltage environments. HV Hipot’s accessory specs are validated against international benchmarks:
| Category | Key Parameters | Safety & Environmental Ratings |
|---|---|---|
| Sensors | Accuracy: 0.1%–0.5%; Bandwidth: 10 Hz–100 kHz; Max current: 0–40 A (AC/DC) | CAT IV 600 V; IP54; -10°C to 50°C operating |
| Test Rods | Length: 0.6–1.2 m; Material: Cu-clad steel; Impulse withstand: 50 kV | IEC 61243-5; Corrosion-resistant coating; 4500 m altitude rating |

On the production floor, we enforce a 100% hi-pot test at 1.5× rated voltage for every sensor and probe before shipment. For example, our RD3000B ground tester accessories undergo 90 V open-circuit validation and 20 mA short-circuit current verification—ensuring field reliability even in noisy substations.
Which Interface Types and Connectivity Options Are Supported?
HV Hipot accessories support USB, Bluetooth, RS232, and optional 4G/Wi-Fi modules for real-time data sync. Meters feature 7-inch LCDs; sensors use banana plugs or BNC; rods include quick-connect terminals.
Interoperability is critical for B2B clients integrating accessories into existing workflows. HV Hipot’s interface strategy balances legacy compatibility with modern IoT readiness:
-
USB 2.0/3.0: Standard on all handheld meters for direct PC data export (CSV/PDF).
-
Bluetooth 5.0: Enabled on RD-series insulation and ground testers for mobile app pairing (iOS/Android).
-
RS232/RS485: Available on industrial-grade sensors for SCADA integration.
