This viedio is inner view of dol oil starter in tamil. @These Starters have Bimetallic Thermal Overload Relay with adjustable current setting as its safety device Relay can be set on different current settings depending upon the fully load current of the motor. Relay is compensated for the increase or decrease in ambient temperature so that it can invariably trip the starter in all weather conditions under abnormal conditions such as overloading & Single-Phasing. (1) Contactors & Coil. (2) Over Load Relay (Overload protection). Wiring of DOL Starter: (1) Main Contact: (2) Relay Coil Connection (3) Thermal Overload Relay Connection Wiring Diagram of DOL Starter Working of DOL Starter Motor Starting Characteristics on DOL Starter: Available starting current: 100%. Peak starting current: 6 to 8 Full Load Current. Peak starting torque: 100% Disadvantages of DOL Starter Advantages of DOL Starter Features of DOL starting For low- and medium-power three-phase motors Three connection lines (circuit layout: star or delta) High starting torque Very high mechanical load High current peaks Voltage dips Simple switching devices DOL is Suitable for: A direct on line starter can be used if the high inrush current of the motor does not cause excessive voltage drop in the supply circuit. The maximum size of a motor allowed on a direct on line starter may be limited by the supply utility for this reason. For example, a utility may require rural customers to use reduced-voltage starters for motors larger than 10 kW. DOL starting is sometimes used to start small water pumps, compressors, fans and conveyor belts. DOL is not suitable for: The peak starting current would result in a serious voltage drop on the supply system The equipment being driven cannot tolerate the effects of very high peak torque loadings The safety or comfort of those using the equipment may be compromised by sudden starting as, for example, with escalators and lifts.
