Ferro-Damp voltage transformer protection device against ferroresonance

Ferro-Damp is a smart (active) load instrument that eliminates unwanted overvoltage surges and protects voltage transformer in case of a ferroresonance situation.

Ferroresonance, in unforeseen situations, can damage electrical equipment. It may cause earth faults in voltage transformers. In order to damping unwanted sudden overvoltages of ferroresonance and to protect transformers in power systems, it is necessary to use a smart device that provides superior energy security by showing high resistance.

FEATURES

• Effective ferro resonance damping with low resistance at ferro resonance.
• Effective power safety with high resistance at earth fault.
• One Ferro-Damp for all secondary voltage values between 20-120VAC (open-delta).
• Activation time delay to keep other external protection devices unaffected.
• LED indication for status monitoring.
• Small size compared to damping resistors.
• Can be mounted low-voltage part on DIN-rail.
• One Ferro-Damp for the protection of 3 voltage transformers with open-delta connection.

We deliver orders throughout Ukraine, except temporarily occupied territories and war zones. Delivery is carried out by transport and logistics companies chosen by you.

The terms of delivery of the order depend on the availability of goods in the warehouse. If at the time of placing the order, all the selected goods are available, then we will deliver the order within a few days, depending on the remoteness of your region.
