Transition resistance

NGEF Transition Resistance – Product Description

The NGEF Transition Resistance is a vital component used in On-Load Tap Changer (OLTC) systems of power and distribution transformers. It is designed to control and limit circulating current during tap-changing operations, ensuring smooth and safe voltage transition without interruption to the power supply. By temporarily introducing resistance into the circuit, it prevents short circuits, reduces electrical stress, and protects transformer components during switching.

Manufactured using high-quality resistance alloys and precision-engineered metal grids, the NGEF Transition Resistance offers excellent thermal stability and consistent electrical performance. Its robust construction allows efficient heat dissipation during operation, preventing overheating and maintaining stable resistance values. The insulated mounting structure ensures safe installation and reliable performance inside the transformer tank.

The transition resistance is built to withstand high electrical loads, frequent switching cycles, and harsh operating conditions such as heat, oil exposure, and vibration. Its maintenance-friendly design allows easy inspection, cleaning, and replacement, helping to reduce downtime and extend service life.
