Benefits of Replacing a Legacy Transformer Monitor
- Modern Optical Encoder Technology — More accurate and reliable
than legacy analog designs. - Built for Harsh Environments — Higher resistance to lightning
strikes and electrical surges than legacy systems due to optical
isolation and robust design. - Revitalize old Equipment — Easy to install retrofit kits are available
to provide a drop in replacement solution - Improved safety
- Cost Effective due to an optional display that provides notable
savings compared to traditional tap sensor solutions.
Dynamic Ratings Retrofit Tap Position Sensor & Display
Dynamic Ratings provides drop-in replacements and mounting kits for quick and easy applications or replacements for a tap changer position sensor. The Dynamic Ratings Tap Position Indicator sensor (TPI) and tap position display are great replacements for numerous tap changer sensors such as the INCON 1292KS and the INCON 1250B display. Dynamic Ratings TPI also provides reliability by insuring resistance to lightning strikes or other system surges.

Dynamic Ratings Tap Position Indicator sensor (TPI)
The Dynamic Ratings’ Tap Position Sensor is a robust single solution that meets stringent electrical standards to ensure reliable operation and long life. The Tap Position Sensor connects directly to the tap changer on your transformer, using an industry standard optical encoder to detect the position of the tap changer and relay that information to your Dynamic Ratings E3 or C50 Transformer Monitor.

Dynamic Ratings Tap Position Display
The tap position sensor provides a Modbus output that can be read directly by an E3, a C50 or an optional display. The optional display can be provided with the sensor, allowing notable savings compared to traditional tap sensor solutions.
The display also provides a configurable output (typically 4-20mA), allowing use with other brands of monitoring devices.
