NGEF Transformer Diverter Switch

The NGEF OLTC diverter switch employs “flag cycle” system of operation. For each phase they have two main contacts, two switching contacts and two resistor contacts. Transition resistance is connected in connected in series with resistor contact and are important because they ensure that he load current is transferred from one tap to other without interruption .

The NGEF Transformer Diverter Switch is an essential component used in On-Load Tap Changer (OLTC) systems for power and distribution transformers. It is designed to regulate transformer voltage smoothly while the transformer is in operation, without interrupting the power supply. By enabling safe and reliable tap changing under load conditions, the diverter switch helps maintain stable voltage levels and improves overall power quality in electrical networks.

Manufactured using high-grade conductive and insulating materials, the NGEF Diverter Switch offers high current-carrying capacity, low contact resistance, and excellent mechanical strength. Its advanced arc-control system minimizes contact wear and reduces electrical stress during switching operations, thereby extending the service life of both the switch and the transformer. The robust construction ensures reliable performance even in harsh operating environments and heavy-load conditions
