Description
Overview
The Megger DLRO200-115 is a portable digital micro-ohmmeter designed for measuring very low resistances in high-power applications. It delivers test currents up to 200 A DC and measures resistance values from 0.1 µΩ to 1 Ω with better than 1% accuracy. The filtered DC output eliminates magnetic transients, making it ideal for testing circuit breaker contacts, disconnect switches, and busbar joints without tripping protective relays.
Key Features
- Test currents from 10 A to 200 A DC with smooth filtered output
- Resolution to 0.1 µΩ with better than 1% accuracy across range
- On-board memory stores up to 300 test results with notes
- RS232 port for data download to PC or real-time output to printer
- Compact design weighing less than 15 kg for portable field use
- IP54 water and dust ingress rating for harsh environments
- 115 V AC input (North American standard)
Applications
- High-voltage circuit breaker contact resistance testing
- Disconnect switch and isolator measurement
- Busbar joint and connection resistance testing
- Power distribution and electrical network diagnostics
