What is MDB and Smdb? The MDB then feeds SMDBs which are installed midway through the power distribution system at a point where the large distribution cable terminates and several smaller sub-circuits begin. What do you mean by CB in electricity?
What is DB Smdb MDB?
Wiring is carried out to distribute current from a single source to various circuits.
What is Smdb used for?
Electrical Sub-Main Distribution Boards (SMDB) are the integral part of Electrical LV Power distribution network in the end user premises of a medium and large scale projects.
What is the meaning of MDB in electrical?
MAIN DISTRIBUTION BOARDS: Power Distribution is a system, consisting of a Main Distribution Board (MDB), Sub Main Distribution Boards (SMDBs) and Final Distribution Boards, by which the electrical energy is transmitted via branches to reach the exact end user.
What is DB electrical?
A distribution board (also known as panelboard, breaker panel, electric panel, DB board or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
What is SMB daemon?
smbd. The smbd server daemon provides file sharing and printing services to Windows clients. In addition, it is responsible for user authentication, resource locking, and data sharing through the SMB protocol. The default ports on which the server listens for SMB traffic are TCP ports 139 and 445.
What is SM DB?
Sub-Main Distribution Boards: These are the switchboards that although similar construction, are larger than a final distribution board circuit. The boards are installed midway through the power distribution system, at the point in a large distribution cable ends, and several smaller starting sub-circuits.
What is DB and SDB in electrical?
by Muhammad Adnan , Trainee Engineer , colony textile mill limited. MV Mega voltage. MDB Main Distribution Board. SDB Sub Distribution Board. TDB Time to breakdown.
What is MDB full form?
A multilateral development bank (MDB) is an international financial institution chartered by two or more countries for the purpose of encouraging economic development in poorer nations. Multilateral development banks consist of member nations from developed and developing countries.
What is LT panel full form?
Low Tension Panels LT Panel is an electrical distribution board that receives power from generator or transformer and distributes the same to various electronic devices and distribution boards.
What is the formula for dB?
One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio. Expressed as a formula, the intensity of a sound in decibels is 10 log10 (S1/S2), where S1 and S2 are the intensity of the two sounds; i.e., doubling the intensity of a sound means an increase of a little more than 3 dB.
What is dB in signal?
dB (Decibel) The difference (or ratio) between two signal levels. Used to describe the effect of system devices on signal strength. For example, a cable has 6 dB signal loss or an amplifier has 15 dB of gain. This is useful since signal strengths vary logarithmically, not linearly.
What is main switch?
Main switches are elementary switching and protective devices for safe machine control. They can be used, for example, as repair switches to quickly switch off large machines and systems so that maintenance work can be carried out safely.
What ELV means?
Extra low voltageExtra low voltage (ELV) means voltage of 50V or less (AC RMS), or 120V or less (ripple-free DC). Low voltage (LV) means voltage greater than ELV, but not more than 1000V (AC RMS) or 1500V (ripple-free DC). High voltage (HV) means voltage greater than low voltage.
What is MCC and PCC panel?
MCC means MOTOR CONTROL CENTRE (As You know). It is used to control motor feeder. PCCmeansPOWER CONTROL CENTRE(As You Know). It is used toPower feeder. Generally, MCC feeds from the PCC panels.
What is MCCB circuit breaker?
A moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical circuit from excessive current, which can cause overload or short circuit.
Is MCB full form?
The full form of MCB is Miniature Circuit Breaker. It is a kind of electronic switch that functions automatically.
