HDE
Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang HDE dari 3G Electric.
What voltage ranges do HDE hot stick-compatible detectors cover?
HDE offers hot stick-compatible detectors spanning from 120 V to 500 kV, with specific models covering narrower ranges such as 4 kV to 12 kV, 4 kV to 35 kV, or 4 kV to 230 kV. The PRX-500B and PRX-500/K10 models cover 120 V to 500 kV at 25 to 400 Hz, while the T200XMR series operates at 50/60 Hz. Always verify the model’s rated voltage range against your system voltage before use.
Do HDE voltage detectors have CAT safety ratings?
Most HDE voltage detectors do not carry a published CAT safety rating. An exception is the PRX-69D proximity voltage detector, which is rated CAT II. For applications requiring specific overvoltage category compliance, verify the model’s specifications or contact 3G Electric for guidance. The absence of a rating does not necessarily indicate non-compliance, but it should be factored into your risk assessment.
What types of testers does HDE manufacture besides voltage detectors?
HDE manufactures transformer and capacitor testers, such as the TL-AST-M model, which performs open and shorted checks with audible and digital display feedback. This tester operates at 6 V to 6 V and is designed for low-voltage testing of windings and capacitors. It is not a high-voltage insulation tester but a continuity and short-circuit checker for components.
Are HDE hot sticks compatible with other brands’ detectors?
HDE hot sticks are designed primarily for use with HDE detectors, but some models may be compatible with industry-standard universal hot stick fittings. For example, the PRX-69D detector is listed as compatible with the Greenlee S-4H hot stick. Check the specific detector’s compatible hot stick listing or consult 3G Electric to confirm interoperability with your existing tools.
What is the frequency range for HDE voltage detectors?
HDE voltage detectors are available in two frequency ranges: 50/60 Hz models (e.g., T200XMR series) and 25 to 400 Hz models (e.g., PRX series). The 50/60 Hz units are suited for standard power grids, while the wide-band models can be used on variable-frequency drives or higher-frequency systems. Select the model that matches your system’s nominal frequency.
Do HDE detectors include any carrying accessories?
Yes, HDE detectors typically include carrying cases or holsters. For example, the T200XMR-0412/K01 comes with a CS-TAG200X carrying case, and the PRX-500B includes a PRX-HS carrying holster. The TL-AST-M tester includes a B-8 bag. These accessories are listed in the product specifications and are included with the unit.
