TR-1 / TR-1P
Turns Ratio Meter 1 Phase
Description
Raytech Single Phase Transformer Turns Ratio Meter TR-1/P is designed to be a rugged and reliable automatic transformer Ratiometer. This system has a high degree of accuracy and can measure ratios up to 4000:1. The design of this test system is based upon the popular Raytech Automatic Three Phase test set: TR-Mark III.
This system is a battery-operated instrument, designed for highly accurate readings on-site with laboratory precision. It is a lightweight system that comes complete with its rugged waterproof field case.
Advanced Protection: Upon powering on the system initializes itself with a self-calibrating, circuit checking sequence. If any problems are detected during this initialization period, or during operation, the operator is immediately notified.
The system constantly monitors the condition of the transformer under test. The TR-1/P can even recognize shorted leads and will terminate the test without any damage to the test equipment. This works especially well when test leads accidentally fall free from the transformer while under full voltage measurement. This, incidentally, is one of the many reasons why we can extend our warranty to 2 years.
