Liquid Resistance Starters PulseTech
Background of our Technology Partner Our LRS (Liquid Resistance Starters also known as Liquid Rheostats) are manufactured by MKS Anlasser, Germany that manufactures very high-quality and cost effective Liquid Starters that are mainly used in Slip Ring Motor applications.. MKS can look back on more than 100 years of expertise and experience in Working of LRS Starter: The LRS is a rectangular tank having electrolyte in it and works on the principle of resistance cutting. The electrolyte solution of Sodium Carbonate ( 𝑁𝑎2𝐶𝑜3) acts as a special liquid resistor, is connected in series to the rotor circuit of slip ring motor. Basically, the liquid resistor consists of metalLRS Starter Power System Studies

2 x 1.5MW 11kV Slip ring Motors with liquid resistor starters
very interesting in deed. We do not plan to have one "rheostat" (liquid resistor starter in my case) but 2. One for each motor, the starting will be interlocked on the MV contactors. In the event there is an issue with one of the motors, the client would like to run the knives with just one motor in use.The short is placed in position with a shorting contractor. A good turn-down ratio will limit the starting torque of the motor to an acceptable value. A good turn-down ratio for a 5mW LRS is a 100 or more. The starting torque of a Wound Rotor Induction motor should not be more than 120% of the rated torque. LRS working temperature range.HOW TO TEST LIQUID RESISTANCE STARTERS SDG

Motor Starting Equipment RWW Engineering
RWW Engineering has had the license to manufacture the AOIP (France) range of products since 1986. These include “Vapormatic” fixed electrode starters and “EPM” moving electrode starters. Slip ring motors provide high starting torque whilst avoiding high starting current peaks. By using the liquid resistance starters, the startingapplication and the motor and assures a smooth startup of the system. Therefore, liquid resistance starters LRS are commonly used to start up WRIM motors. For liquid starters, the electrolyte solution of Na 2 CO 3 acts as resistor, which resistivity in turn depends on the soda concentration. By changing the distance be-GINO AG
