What is live line tester calibration?
Live line tester calibration ensures these high-voltage safety devices accurately detect the presence or absence of electrical energy in power lines. Calibration verifies that the audible and visual indicators activate at the correct voltage threshold, ensuring reliability for technicians working on electrified rail networks and other high-voltage systems.
Why is calibrating live line testers important?
Live line testers are used to confirm if conductor rails or power lines have been successfully isolated from the mains supply before maintenance begins. Calibration is essential to:
- Ensure the tester’s voltage threshold is accurate
- Maintain technician safety in high-voltage environments
- Prevent incorrect readings that could lead to electrical hazards
- Comply with industry safety regulations and best practices
Without calibration, these devices may fail to detect live voltage or give false negatives, putting engineers at significant risk.
Can live line testers be calibrated onsite?
Yes, Calibrationhouse offers onsite calibration for live line testers across the UK, significantly reducing equipment downtime for customers. This service is particularly beneficial for rail network suppliers and electrical maintenance teams, allowing calibrations to be carried out without removing devices from service for extended periods.
What expertise does Calibrationhouse have in calibrating live line testers?
Calibrationhouse, as part of the Seaward and wider GMC Instruments Group, has over 40 years of experience in the design, manufacture, and calibration of live line testers. Our expertise includes:
- Calibration of Seaward LLT models, the preferred choice of Network Rail
- Testing of various live line tester models used in rail, electrical maintenance, and utility sectors
- Onsite calibration available across the UK
How often should a live line tester be calibrated?
Annual calibration is recommended to ensure the voltage detection threshold remains within manufacturer specifications. Heavily used testers may require more frequent calibration, depending on field conditions and company safety protocols.
To assist customers, Calibrationhouse provides automatic reminders for yearly calibrations.
