what does it mean to dereference array of structures?

struct ConfigConnection
{
  ParameterId metered;     // ParameterId type is "enum"
  ParameterId calibration;
};


// contents of this array are just numbers
const ConfigConnection ParameterGenerator::connections[] =
{
  {ParameterId_GeneratorVoltageAB, ParameterId_CalibrationFactorVoltageAB},
  {ParameterId_GeneratorVoltageBC, ParameterId_CalibrationFactorVoltageBC},
  {ParameterId_GeneratorVoltageCA, ParameterId_CalibrationFactorVoltageCA},
  {ParameterId_GeneratorVoltageAN, ParameterId_CalibrationFactorVoltageAN},
  {ParameterId_GeneratorVoltageBN, ParameterId_CalibrationFactorVoltageBN},
  {ParameterId_GeneratorVoltageCN, ParameterId_CalibrationFactorVoltageCN},
  {ParameterId_GeneratorCurrentA , ParameterId_CalibrationFactorCurrentA},
  {ParameterId_GeneratorCurrentB , ParameterId_CalibrationFactorCurrentB},
  {ParameterId_GeneratorCurrentC , ParameterId_CalibrationFactorCurrentC},
};


for(short i = 0; i < (sizeof(connections)/sizeof(*connections)); ++i)
{
    ...
    ...
}

What does   *connections mean?
