Powder handling equipment (PHE) is a term used to describe the amount of electrical current that a device can safely handle. The term was coined in the early 1980s and refers to the ability of electronic devices to withstand high voltages without damage. Power supplies, converters, and other such components are examples of PHEs.
The purpose of a PHE is to ensure that the correct amount of energy flows into a circuit or system and that no more power is allowed to flow than was initially provided.
Things to consider while buying a PHE
- When you purchase a new piece of electronics, you should always check its specifications to see whether or not it has a PHE rating. This information is usually printed on the box or packaging. If you don’t see anything, ask the manufacturer before buying.
- Always choose a brand name with a strong reputation. Avoid cheap brands because they often lack proper protection against voltage spikes.
Types of PHE
Power handling equipment comes in two main types: AC and DC.
- AC PHEs are used to generate, transmit, and distribute electricity.
- On the other hand, DC PHEs are used to transfer energy between circuits, such as converting alternating current into direct current.
How do PHEs ensure safety?
- PHEs are designed to automatically open upon detection of dangerous conditions such as overcurrents, short circuits, and ground faults.
- It prevents injuries and damage caused by accidental contact with live wires.
- They are typically installed near overhead lines or other high voltage sources.
- They consist of metal enclosures that house circuit breakers, fuses, disconnect switches and other protective devices.
Uses of PHEs
- PHEs are often used in high-voltage applications such as electric trains and ships.
- These devices are also sound in low-voltage systems, such as household appliances and computers.
- It is an essential part of electrical engineering because they ensure that electricity flows smoothly through the system.
- They also prevent dangerous situations from occurring, such as fires or explosions.
- They allow engineers to design circuits that generate less energy waste and operate safely.
Today, PHEs are used for a wide range of applications, from industrial processes to consumer electronics. They allow us to control electricity, generate power, and transmit energy. Without them, we would be living in darkness.
PHEs are made up of metals, plastics, ceramics, fiberglass, etc. The materials used to make these devices determine their strength and durability.
