Product Overview
This mobile voltage detector BO-A 2.0 from HORSTMANN is designed to check for the presence or absence of voltage on medium-voltage railway overhead contact lines. The device is designed for use in networks with 16.7 Hz, 50 Hz, and 60 Hz and provides visual and audible warnings when used in networks with deviating frequencies.Function and Indication
- Voltage indication: red LED and acoustic signal for "voltage present."
- No voltage indication: green LED and no acoustic signal.
- "Ready" indicator: green LED after successful self-test.
- Automatic frequency detection and warning for deviating frequency.
- Type indication: according to Group III of IEC 61243-1 (or VDE 0681-6 depending on version).
Typical Applications
The device is used to verify the presence or absence of voltage during maintenance work on railway overhead contact lines. If the BO-A 2.0 detects a deviating grid frequency, a visual and audible alarm is activated, and the grid condition must be verified.Documentation
