Power Line Combined Lightning & Surge Arrester
It's an electronic era, all the homes, offices, buildings; industries are using sophisticated electrical as well as electronic equipments. Further, increase on the electronics has increased the dependency on the same. So, if some equipment goes faulty then will leave you helpless. Repair, maintenance and replacement costs are increasing day by day.
Surge is the topic, protection from which is must in this era. Sudden increase in voltage is surge. Surges are so fast that none of the safety devices like breakers, stabilizers, UPS, etc. are unable to sense it since, their response time is very slow in milliseconds, whereas surge comes and attack the end equipment in nanoseconds.
Surge enters into a building / installation and subsequently attack the end equipments like TV, Refrigerator, Washing Machines, Music System, Computer, PLC, Variable frequency Drive, CNC Machines, etc.
As you are aware, the lightning current and surge currents will be hazardous to all equipments, wiring, electrical as well as electronic items installed in any building. Damage to or destruction of equipment occurs at precisely the moment when one is dependent on its permanent availability. Apart from the costs for replacement or repairs, further costs are caused as a result of downtime of system parts or even due to loss of software and data.
In general, the damage is manifested in destroyed conductors, PCB's or switches and even obvious mechanical damage to the equipment and building installation. Surge arrester protects the electrical installation from transient caused by thunderstorms and switching processes. As we know, that surges / spikes (transient voltages) from input supply occurs for few microseconds, which can damage your precious equipment within the fraction of a second. Also all equipments has its own voltage range and a limited insulation voltage breakdown voltage, whenever main supply cross that window range, either the running equipment will shut off at the moment when its work is required or can be permanently damage and leave you helpless.
Surge enter into a building / installation through low voltage power supply, data processing systems, telecommunication systems, measurement and control systems and trans-receiver systems. Providing safety measures from all requires installation of all such types of surge arresters.
The most common and damaging source of surges is power line. These surges enters in the following ways:
1.Direct lightning strike on a building / low voltage overhead lines
2.Indirect lighting strikes and nearby strikes or distant lightning strikes or cloud to cloud strikes may cause huge voltage peaks also due to electromagnetic coupling of lightning currents through low voltage overhead lines or through earthing installations.
3.Switching surges: These surges arises from on and off switching operations from switching of inductive and capacitive loads and from breaking of short- circuit currents. Also, electrical and electronic equipments may be damaged thorugh disconnection of production plant, lighting systems, transformers, welding machines, motors, etc.Highest voltage peaks or surges on low voltage network is caused by lightning. These surges can destroy the load completely. Switching surges does not produce highest voltage peaks as lightning, but they occur very frequently and also result in immediate failure of the installation. Surges also results in fast ageing of components used in electrical and electronic equipments and causes gradual damage to the equipment.
To provide protection from such lightning and switching surges, TY5-B+C, combined lightning and surge protector is required. TY5-B+C should be installed at the incoming of low voltage panel or main distribution board, sub distribution boards, UPS, etc. (wherever protection is needed). Provision of TY5-B+C in your low voltage network will provide complete safety from lightning and switching surges.
