Compact dual and triple HLR starters comprise a single liquid electrolyte tank which contains multiple sets of electrodes (liquid resistance banks) to drive multiple motors. This ensures electrolyte level, temperature, and strength/resistance is the same for each driven motor thereby ensuring their acceleration rates are identical.
Mill motor, 2.9MW, 6.3KV, rotor current: 775A, rotor voltage: 2770V In this case sometimes we recorded 775A as starting current and in other times we recorded 400 A for rotor current during start and for stator the current is variable, in some case it was 85 A, and in other was larger than 400a. This motor starts with liquid starter.
