Gas discharge tube arresters (GDTs) are the most important components for effectively protecting sensitive electrical and electronic equipment from potentially damaging power surges or lightning strikes. The PMT3 (310) 15014 arrester is a three-phase arrester designed to provide excellent protection from lightning strikes, with improved surge capabilities, stable characteristics, fast response time and long service life.

The PMT3 (310) 15014 arrester is designed primarily for the protection of three-phase power systems with voltages of up to 15 kV. It has a maximum continuous operating voltage (MCOV) of 14 kV, a short-circuit current rating (SCCR) up to 200 kA, and a switching impulse withstand voltage (SWIV) of, 150 kV. This arrester also has an internal switching-Off voltage, which is lower than the maximum continuous voltage, so that it can switch itself off in the event of an over-voltage situation.

The design of the PMT3 (310) 15014 arrester enables it to respond rapidly when subjected to voltage surges, such as those that accompany lightning strokes. The arrester has an internal voltage regulation to maintain its own stability in an over-voltage situation. The arrester also has an external overvoltage protection circuit to protect the power system from sudden surges.

When lightning strikes or other over-voltage situations occur, the PMT3 (310) 15014 arrester creates a gas discharge which reduces the voltage to a safe level. This is known as the quenching mechanism and it is achieved by the movement of electron particles which respond to the increased electric field and produce a spark gap between the electrodes in the GDT. This spark gap reduces the electric field so that the voltage can be safely reduced before damaging the circuits.

In addition to its lightning protection capabilities, the PMT3 (310) 15014 arrester is also designed to provide protection from transients caused by switching operations and when faults occur on the power system. The arrester is also designed to provide protection from damaging surges generated by faults on the power system. In these situations, the gas discharge tube quickly extinguishes the resulting arc, thereby preventing further damage to equipment or infrastructure.

The PMT3 (310) 15014 arrester is designed to be used in a wide range of applications, including industrial, commercial, and residential power systems. It is also suitable for use in power systems with both AC and DC power supplies. In addition, it can be used in combination with other forms of surge protection, such as surge arresters, surge suppressors, and varistors.

The PMT3 (310) 15014 arrester is a highly reliable, cost-effective solution for protecting power systems against lightning and other electrical surges. Its coverage area makes it an ideal choice for a variety of applications, and its compact size and easy installation make it suitable for most locations. In addition, its superior surge protection and response time provide maximum protection for sensitive electrical equipment.
