Automatic cathodic protection rectifier – ASKZ
APPLICATION
- ◆Metallic and reinforced concrete structures even located in the zone of dynamic stray currents
- ◆Forced drainage of stray currents
MEASURING AND MONITORING PARAMETERS
- ◆The rectifier is equipped with measuring and telecommunications block (device TE-RCU/SCR) and ER probe for verification of the following parameters:
- ◆Value of output voltage and current from the CP rectifier station – Uout, Iout
- ◆Intensity of DC current across a coupon /soil surface – Idc
- ◆Intensity of AC current across a coupon/soil surface - Iac
- ◆Drainage current intensity - Ip
- ◆ON/OFF potential of steel structure vs the reference electrode Cu/CuSO4 - Eon, Eoff
- ◆Value of the alternating voltage v.s. earth- Uac
- ◆Corrosion rate - Vcorr
- ◆Density of DC current across a coupon /soil surface - Jdc
- ◆Density of AC current across a coupon/soil surface - Jac
- ◆Power supply status
- ◆Door position: open/closed
- ◆Alarming notifications for all measuring values in case that measuring varies from the set limits
- ◆Alarming notifications informing about the energy supply interruption and the open door
CONTROL AND COMMUNICATION
- ◆Remote: GSM/GPRS; MODBUS
- ◆Manual: USB port for PC/lap top or via keyboard
