A DC Voltage Electroscope is a detection device used to check the presence of direct current (DC) voltage in electrical systems, ensuring safety before maintenance or operation.

DC Voltage Detection

Used to verify whether DC transmission lines, cables, or equipment are energized.

HVDC System Maintenance

Commonly used in high-voltage direct current (HVDC) transmission systems to confirm the presence or absence of DC voltage before maintenance.

Substation Safety Verification

Applied in converter stations and substations to check DC voltage on equipment such as busbars, filters, and converter components.

Electrical Inspection and Testing

Used during inspection, testing, and troubleshooting of DC electrical installations.

Worker Safety Protection

Helps ensure that circuits are de-energized and safe to approach, reducing the risk of electric shock.

Typical Features

Designed specifically for DC voltage detection

Visual and/or audible indication when voltage is present

Used with insulating rods or poles for safe distance operation

Suitable for high-voltage DC environments
