4. 3 Electrical system
4.3.1 Design principle
4.3.1.1Instrument control system can supervise the whole air separation plant producing process efficiently, ensure the plant running steadily and conveniently.
Provision of motor control, protection and measuring device must be in accordance with relative national standards and code. There is one HV incoming line designed. Voltage reducing start for HV motor to reduce impact of network and machinery. Busbar voltage is not lower than rated 85％ of it during the start of the motor. There are two incoming lines for LV power supply. One line is used as s/b. There is local panel for motor equipment in which electric meters, signal and control element are provided. Busbar voltage is not lower than rated 15％ of it during the start of the LV motor. Close loop adjustment by TSCR for electric heater of molecular sieve. Power supply:
- High voltage 10KV±5% 3-phase, 3-wire, neutral point not earthing power supply
- LV 380V/220±5% 3-phase, 5-wire neutral point earthing power supply
- DC power supply: DC24V
- Buyer should provide relative network system drawing, short-circuit capacity, and current value for single phase earthing .

Instrument control design principle and scope of supply
DCS concentrating and dispersing control system will be decided by final design for selction of the provisions. 2 operation platforms are in the operating rooms to monitor the parameters of the plant with the function of display, operation, regulation, memory , starting and protection interlock. The interlock function can start and stop the plant automatically according to the requirement, which also can be operated manually. There is 1 printer in the operation room to print the parameters and functions when the plant is running. There are Local panels for each machinery, which can display parts of parameters, oeprating, alarm and interlock. There is a analysis room. The analysis device is in the panel, the parameter is displayed, recorded and alrmed in DCS system. Instrument power: 220VAC and 24VDC. DCS system needs continually power supply. The power for instrument system is supplied by the power supply plate of the instrument system.
