Regular testing of electrical equipment can lead to the early discovery of internal problems, therefore allowing the electrical components to be reconditioned, avoiding future problems.
For a reliable MicroOhmmeter, consider the Vanguard Micro-Ohmmeters available for rent, lease or purchase from Protec today.
The Vanguard Auto-Ohm 100 Ampere Micro-Ohmmeter features microprocessor-controlled measuring of very low resistances ranging from 1 micro-ohm to 300 milli-ohms with high accuracy.
The Vanguard Auto-Ohm 100 is field-portable, rugged, and easily operated by first-time users having a minimum of training.
The Auto-Ohm-200 S3 Ampere Micro-Ohmmeter is Vanguard’s fourth generation, microprocessor-based, true DC micro-ohmmeter. It is designed for testing EHV circuit-breaker contact resistances, bushing contact joints, welding joints, or for any low-resistance measuring application.
This high current and very lightweight (16.8 lbs/ 7.6 Kg) micro-ohmmeter is designed to meet the IEEE C57.09-1999 (5.15) requirement for testing circuit breaker contact resistance.
