How ESP transformer works?
Basic Principle of ESP A high voltage is applied to the discharge electrode, generating a corona discharge that produces minus ions. The electrically charged dust is accumulated on the collecting electrode by an electrical field.
What is the function of the transformer rectifier on an electrostatic precipitator?
A transformer-rectifier (T-R) set along with an automatic voltage controller (AVC) supply the high-voltage and unidirectional current to the discharge electrodes. Several T-R sets are normally required to power a precipitator.
What is ESP Trcc?
Transformer Rectifier Set in short know as TR Set, Transformer Rectifier Set is one of the major equipment of the Electrostatic Precipitator. Transformer Rectifier set is used to convert the line input current and voltage into high voltage DC supply for the ESP.
What is a TR set?
The Transformer-rectifier set, also called a TR or a TR set, converts the low voltage of the plant power system to the high voltage required for precipitator operation.
What are the parts of ESP?
The main components of an ESP consist of collecting electrodes/plates, discharge electrodes, inlet and outlet perforated screens, insulators for the discharge electrodes, rappers, and one or more electrical transformers.
What is difference between transformer and rectifier?
Rectification is the most widely used one among them. The transformer used as the power source of the rectifier is called the rectifier transformer. Most industrial rectified DC power supplies are obtained from AC power grids through rectifier transformers and rectifier equipment.
Which transformer is used in rectifier?
While the use of the type of transformer in a rectifier depends on the voltage requirement or to meet desired operating conditions, a step-down transformer is used mainly to reduce the voltage.
What happens if an electrostatic precipitator is not used?
Electrostatic precipitators can capture fine particles (i.e., those that are smaller than 2.5 microns [0.0001 inch] in diameter), which are especially dangerous if released because they can be drawn deep into the lungs and can trigger inflammatory reactions.
How do you reduce corona effect?
How Corona Effect is Reduced:
- By Increasing Conductor Size: The voltage at which corona occurs can be raised by increasing conductor size.
- By Increasing Conductor Spacing: The corona effect can be eliminated by increasing the spacing between conductors, which raises the voltage at which corona occurs.
How do you test a transformer?
To test your transformer, simply touch the red and black pins of your ohmmeter to the opposite ends of the transformer’s wiring. Read the display and compare the resistance on your ohmmeter to the resistance stated on the transformer’s data sheet. This is sometimes listed on the transformer’s enclosure.
Which type of transformer is used in rectifier?
What is the principle of operation of an ESP rectifier transformer?
ESP Rectifier transformer M.G.Morshad / aCM Transformer Mtce / TPS II 2. Principle of operation • Electrodes at high voltage create a corona effect (ionized atmosphere) surrounding them.
How many kV hipot tests are required for a transformer?
The transformer shall be a two-winding, single phase power rectifier type. The high voltage windings shall be insulated for 1.5 timers rated voltage. The low voltage windings shall be insulated for 2.5 KV Hipot tests.
Which is the best transformer for electrostatic precipitator?
