Most power resistor manufacturers in the market today use or copy grid resistor designs that originated in the early twentieth century. While reliable, these conventional designs are restricted by parameters set to accommodate manufacturing efficiency. The T&B grid resistor designs allow multiple combinations of element cross-section using fewer gauges of steel. The grid parameters are designed by a computer program which evaluates a given power application to confirm grid material, pattern, and thickness.
T&B offers numerous raw material selections to customize your resistor to the most efficient and economical solution. This technology permits variations of the grid design and proves more efficient and less restrictive than conventional grid designs. Telema & Berger resistors also incorporate solid ceramic insulators that possess twice the temperature rating of conventionally used mica insulation.
T&B offers solutions for Neutral Grounding Resistors, Harmonic Filter Resistors, Load Testing Resistors, Dynamic Breaking Resistors, AC/DC Motor Control Resistors, and Transit / Railway Resistors.
