While much attention is given to the need to safeguard critical systems against power outages, the fact of the matter is, it doesn’t take a complete blackout to wreak havoc on sensitive electronic equipment. In fact, a wide range of power anomalies can cause significant damage to your equipment. One ongoing threat is dangerous voltage surges, which can result from culprits ranging from lightning strikes to the routine switching of large loads in data centers and process control environments.

Safeguarding equipment with a common type of power conditioning known as a transient voltage surge suppressor (TVSS) is a simple yet highly effective measure to help prevent damage to your devices. (And if you’re thinking you don’t need a TVSS because you already have an uninterruptible power system (UPS) in place, keep reading. One of the greatest misconceptions is that UPSs will protect equipment from lightning strikes or high-energy electrical spikes; they don’t.)

Installing a transient voltage surge suppressor helps to guard against these damaging voltage surges. TVSS accomplishes this surge protection with a switch that constantly monitors the AC voltage input and output waveforms. Although nothing happens under normal operating conditions, when the TVSS senses a voltage that exceeds operating parameters, it will clamp the voltage to a safe level before it reaches the equipment, with excess current diverted to the ground.

It is important to note that even with a TVSS installed, the force of a direct lightning strike is still capable of damaging sensitive equipment. While no device can guarantee complete protection against a such a hit, one type of TVSS known as a lightning arrester provides the best protection when installed at the main service entrance.

The UL 1449 standard specifies four different types of TVSS, which are determined by the installation location. Type 1 TVSS is usually installed on the line side of the service entrance, but is applicable anywhere within the power distribution system. Type 2 TVSS is installed on the load side of the service entrance, or branch panel. Type 3 TVSS ― which usually consists of power strips, receptacles or plugs ― is installed near the protected equipment. t is known as surge protection module. Finally, Type 4 provides protection to servo motors, PLCs and other devices used in industrial applications.

Transient voltage surge suppressor, surge protective device, voltage surge suppression, surge arresters, lightning arresters, arc flash protection, surge monitors, overcurrent protection … and the list goes on. With so many potential product lines, it can be difficult to know which devices are the same and which are different ― making it even more challenging to determine the optimal protection device for your electrical equipment. Worse still can be deciphering the extensive range of acronyms that encompass the terminology of power distribution and critical power protection devices, leaving you to wonder if you’re trapped in a steaming pot of alphabet soup. But don’t despair; we break it down here.

Transient voltage surge suppressor (TVSS) and surge protective devices (SPD) both refer to a piece of equipment that can protect low-voltage electric systems from damaging transients, spikes or surges. The term TVSS tends to be more popular in countries that adhere to UL standard, such as the U.S. and Canada. Although TVSS devices have always belonged to a larger family of surge suppression devices known as surge protective devices, or SPDs, beginning with UL 1449 3rd Edition and the 2008 National Electrical Code, the term SPD formally replaced the labels of both “TVSS” and “Secondary Surge Arrester.”

So if TVSS and SPD are the same devices, what about another commonly tossed-around acronym, TVS? While they sound similar, it is important to note that TVSS and TVS are not interchangeable terms. TVS is the abbreviation for transient voltage suppressor, which is an electrical component or diode that serves the purpose of a surge suppressor. TVS is one of the three most common elements used to manufacture TVSS devices, with the others being MOV and GDT.

Damaged electronic equipment. An increased need for service calls. Unexplained system shutdowns or errors. If you’re experiencing any of these symptoms, transient voltages may be the culprit. Transient voltage surge suppressors can be deployed with any equipment that connects to electricity, telephone lines or computer data/communication lines, including computers and peripherals such as printers, monitors, speakers, fax machines and modems; PABX and communication systems; entertainment components; medical devices such as surgical instruments and scientific equipment; security systems; and other electrical equipment.

One of the most common misunderstandings about UPSs is they will protect equipment from lightning strikes or high-energy electrical spikes. While this may be true for some smaller single-phase units, the vast majority of medium to large three-phase UPS models do not provide internal lightning or TVSS protection. Because of this, it is critical to install a TVSS at the electrical panel feeding the input power to your UPS. Both the rectifier and bypass inputs to the UPS require protection.

The Room is the first tip.

The space where we have our breakfast will be the first thing that will make a good or bad impression on a client if we follow the route he takes. A general control of the state of the salon prior to the opening of the service can save us a complaint.

We like to enter spaces that make us relax. The time of breakfast is used by most of the clients to get ready for their meeting in the morning, to organize their tourist visits, or to just relax before the hustle and bustle of the day begins. A room with the correct temperature, soft music, a clean and fresh smell, and no air conditioning, will be a plus to invite that special moment that is breakfast.

The second tip is customer service.

The pace of the breakfast room is frantic at certain hours of the morning, and all of us who have reviewed breakfast services know that.

It has happened to me many times that there is a lot of customers at the same time, the waiter is not enough, and they run from one place to another to try to have everything under control. This is known to the hotel staff, but in view of the client, the impression we give is of poor personal attention and little provision of services. I like that an employee gives me a friendly look and smile even if they can't stop to greet me or seat me at a table, even if they can't stop to greet me. The client should not be affected by the lack of staff to cover the service.

If the waiter is able to take another minute to come to my table and make sure that everything is correct, then you can always take a second to smile at a customer.

The third tip is cleaning.

Coffee remains, dirty crockery, and unassembled tables are piled up in various places.

This is something that I have seen repeated many times in establishments and it really makes you feel bad. The breakfast room has no table to sit down and it's very unpleasant to arrive there. If you add to this, that no one from the team is looking out for you and offers to prepare a table for you, you can already have the best products in the world in the buffet and all the possible variety, which is sure to be very negative for that client.

Is it quantity or quality?

Everyone will have their own opinions at this point. I would always put quality before quantity. If the quality of the product is lousy, it is useless to have a buffet breakfast with 500 different references. Coffee and orange juice can be used to determine if a customer is in front of a good breakfast. If we don't drink coffee at home, why would we drink it in a place where we are paying for it?

And the powdered juices? This would be another point apart and I think it would be enough for a whole post, but it is something that will never enter my head.

I am aware that we all want to keep our costs down, but there are certain aspects that are not negotiable. You should make monthly and responsible purchases that are appropriate to your forecast of services, have different products from each family and alternate them by days at the buffet. If you can't afford to have 5 different types of juice per day, you can put 3 and alternate them, but make sure that what you have is up to the expectations of your customers.

Replenishment of products is a tip number 5.
