| Description
The Megger TRS1PLUS Transformer Ratio Standard is a universal test unit used to verify the accuracy of transformer ratio meters. The key feature is its versatility, which includes the ability to simulate both step-up and step-down transformer ratios for comprehensive testing. |
| Key features
High accuracy: It provides a highly accurate reference, typically with an accuracy of 0.01%. Universal compatibility: It is compatible with all brands of transformer turns ratio meters, making it a flexible tool for calibration facilities and field work. Dual functionality: Its ability to simulate both step-up and step-down configurations means it can test a wider range of TTRs, including traditional crank-handle meters (which typically test in step-up mode) and modern digital meters (which often test in step-down mode). Kelvin configuration: It uses a four-terminal Kelvin measurement method, which eliminates errors caused by lead resistance. Rugged design: The unit is built to be durable enough for field use in addition to its function as a laboratory calibration standard. |
