Telecommunication power systems are an essential part of telecommunications infrastructure. These systems help provide stable telecommunication services even during grid power interruptions and fluctuations.
Telecom power system markets are expected to grow at a CAGR of 8.8% during the forecast period. This growth is attributed to the increasing demand for telecommunication networks and the growing use of renewable energy sources.
The telecom power system is an integral part of any telecommunications operation. Without power, computers, communication networks, and other modern electronic devices will not function correctly.
Telecommunication towers and data centers rely on generators to provide reliable power when the mains power fails or is interrupted. These generators can be Diesel or gasoline engine driven and permanently sited at the telecom tower or in an IT building.
Currently, most countries are adopting renewable energy sources for electricity production. It increases the demand for backup power from solar and wind generators.
However, these systems can only succeed if the generators are maintained. It can lead to more expensive repairs or even permanent damage to the equipment.
The telecom generator market is segmented based on components, grid type, power source, power rating, and technology. The market is projected to grow at a compound annual growth rate of 8.8% from 2021 to 2028.
Batteries are a critical part of a telecommunication power system and provide a backup power source in the event of a mains failure. They can be either lead-acid or lithium-ion and serve a variety of functions.
Lead-acid batteries are the dominant type of battery used in telecommunications. They are easy to maintain and offer a high safety profile.
Lithium-Ion batteries are a new generation of battery technology growing in popularity. They are 50% lighter and offer a 3X more extended life expectancy than lead-acid batteries.
Telecommunication batteries are typically used to back up network equipment, run DC equipment and provide power for base stations located remotely from a national grid. These batteries are often charged via hybrid sources such as a solar photovoltaic (PV) system or generator.
Through computer modeling, rigid components materials selection and design criteria, and state-of-the-art automated manufacturing, it can optimize power, size, life expectancy, features and costs to meet the unique demands of telecoms applications.
Uninterruptible Power Supplies (UPS)
UPSs deliver power backup and surge protection for plugged-in electronic devices in case of a mains voltage sag, outage or another anomaly. These units also help to prevent data loss, equipment damage and lost revenue.
UPS systems can range in size and power capacity to meet specific needs. Depending on the model, they can protect computers, peripherals, network servers, data centers, and other IT infrastructure.
Most UPSs deliver power through a high-efficiency mode that allows for low operating expenses and a premium power-protection mode that maintains a clean, consistent, efficient and reliable supply of electricity in the event of a utility failure. This feature can save a company a significant amount in operating costs.
Typical UPSs use an autotransformer to correct minor power fluctuations, such as under or over-voltages, without switching to battery power. They are best suited for consumer electronics, PCs, entry-to-mid-range servers and networking equipment.
DOT and ITS managers need access to reliable, stable power supplies for their traffic control and communications systems. A commercial UPS system ensures that these vital telecommunication and transportation facilities never interrupt communication due to power loss.
Inverters convert power from one type of energy source (usually DC) to another. They may produce a square wave, sine wave, modified sine wave or pulsed wave, depending on the circuit design.
Many inverters now use transistors or other semiconductor switches in place of mechanical switches. It allows for greater voltage and current ratings, lower power loss, less heat and higher reliability.
Low-pass filters are frequently used on the inverter circuit to lower the harmonic content of the output waveform. These devices can be positioned on the transformer’s input or output side or both.
Modern inverters also help balance reactive power, which is the power that comes from the electricity that isn’t in sync with other types of power. It can occur when batteries or solar panels have an excess voltage or current not used.
Inverters can be programmed to react to signals from an operator and change their power output as the other supply and demand on the electrical grid fluctuates, a grid service called automatic generation control. Before these powers were widely used, however, there was still a ton of study tremendous be done.
Almost every building with an electrical system uses circuit breakers to protect it from short circuits, undercurrents, and other potentially dangerous or costly damages. If these devices fail, they could be the source of fires or harmful arc flashes that can kill workers or damage equipment.
One of the most critical functions of circuit breakers is their ability to communicate what type of fault caused them to trip. It allows maintenance, production, and other departments to manage better energy, assets, and electrical network quality.
Another valuable function of medium-voltage circuit breakers is a mechanical counter that records the number of close/trip cycles they’ve experienced. This data can be analyzed to direct further maintenance or intervention procedures, like replacing contacts.
General Electric’s Magneblast and GE Power Defense circuit breakers feature this feature. This count value is valuable for maintenance, as these breakers’ repetitive closing and tripping will wear down contacts over time. The breaker must be serviced at manufacturer-specified intervals of close/trip cycles to keep it working safely and efficiently.
