A current transformer measures electricity without diverting the current into the measuring instrument, which could be hazardous. It uses the magnetic field produced by the current to create a current that is directly proportional to the device or line being measured. It is an important tool in electrical engineering for safety and efficiency monitoring. A […]
Pulse transformers conduct electrical currents in a pulse-like rhythm, making them ideal for telecommunication circuits, digital logic situations, and lighting situations. There are two main types: signal and power. Power models require low coupling capacitances and high breakdown voltage and insulation resistance. High voltage pulsed transformers have pulse output voltages ranging from 100 to 500 […]
A voltage transformer can step up, step down, or transfer electricity between circuits. It relies on mutual induction and is useful in high voltage scenarios. High voltage transformers are used in power grids, while low voltage transformers are used in electronic devices. They can be used to convert voltage for use in different countries. A […]
A capacitor voltage transformer (CVT) is used in high voltage circuits as a metering device and to protect specific parts of the circuit. It increases the input signal and reduces it to a level within the circuit’s parameters. A CCVT is a more expensive version that can handle higher amounts of input signal and distribute […]
Transformer oil is a highly refined mineral oil used to cool and insulate electrical devices such as transformers, circuit breakers, and high-power switches. It is important to use the correct grade of oil for indoor or outdoor use and to have it added by a professional to avoid malfunction. The devices used to alter the […]
Transformer oil is used to cool and insulate electrical transformers, made from highly refined mineral oil. It is important to use the correct grade for indoor or outdoor use and to add it correctly to prevent malfunctions. Professionals should be hired for this task. The devices used to alter the electrical flow are known as […]
Delta-wye transformers convert three-phase electrical energy into power with a neutral wire. They are commonly used in industrial, commercial, and residential areas. The term “delta star” is used in Europe. They increase the lifespan of electronic distribution networks and reduce stress on motors and power cables. They are commonly found in AC motors and manufacturing […]
A trigger transformer starts pilot currents for gas-filled cold cathode devices. It generates high voltage bursts and works with capacitors to produce resonance. It is similar to an electrical ballast and is used for flash photography and lighting effects. The High Voltage Self Limiting Transformer (HVSLT) is used for neon tubes in signs. A trigger […]
A transformer transfers electric current between power circuits, typically with AC. Buck-boost transformers alter voltage up or down by up to 20% to regulate input current for devices requiring specific voltage, such as engines and lighting. There are automatic and static types, and they may be used to adapt equipment to different power systems. It’s […]
A zigzag transformer creates a ground reference point from a three-wire three-phase power line. It uses a special design to derive a new set of three-phase vectors and has two sets of windings for each phase. The neutral point is at the same earth potential when loads are balanced, but there will be a voltage […]
A control transformer steps down high main circuit voltage to a lower voltage for use in industrial start-up circuits. It provides a stable and efficient power supply for contactors and relays, and allows for the use of lower, safer control circuit voltages. A control transformer is a device used to transform or “step down” a […]
Isolation transformers isolate unstable frequencies within a signal, transforming them into a clear output. They can be used in audio and video transmissions, as well as in electronic devices to stabilize circuits. Standalone units can process multiple input signals and isolate irregularities over a wider range of bandwidths. The type of irregularities that can be […]
Power transformers convert incoming electricity to a higher or lower value, regulating voltage and current flow. They are used in electrical grids and everyday devices, with safety features to prevent damage or overvoltage. Sometimes known simply as a transformer, a power transformer is a device used to convert incoming electricity or voltage to a higher […]
A flyback transformer generates high voltage in CRT devices. It has high requirements for high voltage isolation and its internal structure must be moisture-free. Unlike normal transformers, it generates high voltage in its secondary winding. Impedance depends on frequency and line output transformers are used for power, audio, and other applications. Vacuum tube circuits use […]
A rotary transformer is a type of variable frequency transformer that allows electrical signals from rotating components to connect without generating unwanted activity. Its unique design reduces wear and friction, promoting longer equipment life and lower repair costs. It is commonly used in recording equipment and motors that rely on AC power. A rotary transformer […]
Transformer substations convert electrical energy from mass power to local power and vice versa. They are found in the center of electrical cables and contain various pieces of equipment. They convert bulk energy into premium energy for local use and can also send excess power back to the grid. Some substations have specialized functions, such […]
Energy efficient transformers use highly conductive materials to reduce power loss during energy transfer. Traditional transformers lose 40-50% of power, while energy efficient transformers only lose 20-25%. Conductive materials like amorphous metal improve power transfer and reduce carbon dioxide emissions. A transformer is an electrical device that transfers electrical energy from one electrical circuit to […]
Distribution transformers step down voltage for utility customers. They can be pole-mounted or pad-mounted and use different insulators. Utilities can move or add transformers as needed, but outages may occur during maintenance. The utility is responsible for installation and maintenance, and acts quickly to restore power after a failure. A distribution transformer is a device […]
