Overvoltage and overload protection made by surge arresters LVA-280 serial.

The LVA-280 surge arrester series provides overvoltage protection in low-voltage power systems by safely diverting transient surges (from lightning or switching operations) to ground. It is not designed for continuous overload protection like fuses or circuit breakers, but it complements them by protecting cables, transformers, and equipment from short-duration high-energy impulses

How LVA-280 Surge Arresters Work

Overvoltage protection:

• Limits dangerous voltage spikes caused by lightning strikes (direct or indirect).
• Handles surges from switching operations (motors, capacitors, breakers).
• Protects insulation of cables, transformers, and switchgear.

Overload protection:

• Surge arresters are not intended for long-term overload current protection.
• They work in tandem with fuses or circuit breakers that interrupt sustained overloads.
• Arresters absorb and discharge short, high-energy impulses safely to ground.

What analogs of Overvoltage and overload protection made by surge arresters LVA-280 serial?

The LVA-280 surge arrester series is a low-voltage protective device designed for distribution networks. Jera Line manufactures SA-type surge arresters that serve as analogs to the surge arrester LVA-280, offering similar overvoltage protection for cables, transformers, and switchgear in residential, commercial, and industrial systems

The SA-0.28/10 surge arrester, produced by Jera Line, plays a crucial role in protecting electrical systems from overvoltage and overload conditions.

Specification:

Key Features

• Eliminating the need for a voltage grading system for the voltage network.
• Protecting from both overvoltages and under-voltages.
• Reducing the risk of equipment damage due to transient-events such as lightning strikes or switching surges.
• Eliminating the need for frequent inspection and maintenance, resulting in cost savings.
• Metal oxide surge arresters are an effective way to protect electric networks and equipment from high-voltage surges, helping to ensure safety and reliability.

• Essential Protection for Electrical Networks

Power systems often face sudden voltage spikes caused by lightning strikes, switching operations, or faults in the grid. These overvoltage events can damage cables, transformers, and sensitive electrical equipment. The Jera Line SA-0.28/10 surge arrester which is analog of surge arresters LVA-280 serial is designed to absorb and safely discharge these harmful energy surges, preventing costly downtime and equipment failure.

Applications

Jera Line’s SA-0.28 surge arrester is suitable for use in:

• Overhead power distribution lines
• Transformer secondary protection
• Low-voltage distribution networks
• Renewable energy installations (solar, wind)

Its easy installation and low maintenance requirements make it a preferred choice for both utility companies and industrial users.
