Page 4: Warnings And Safety
Warnings and safety General safety guidelines DANGER! Incorrect use Unjustified removal of protection devices, incorrect use, faulty installation or inappropriate operation could represent a serious risk to personnel and equipment. All work relating to transportation, installation, commissioning and maintenance must be performed by experienced, qualified personnel (see IEC 364, CENELEC HD 384 or DIN VDE 0100, as well as national specifications for installation and accident prevention). -

Page 6: About The Mib
The measurements are shown on the built-in display. The MIB is available in two versions: • MIB 8000 (basic) • MIB 8000C (with communication + optional I/O extension module) True RMS values on all 3-phase network topologies are measured with/without neutral and with both balanced and unbalanced load. -

The shield of the RS-485 cable must be connected to the ground at one end only Measurements Measurement Description Voltage Actual voltage of each phase-phase and phase-neutral. Current Actual current of each phase and neutral current. Active power (P) Active power of each phase. Reactive power (Q) Reactive power of each phase. -
Page 9: Measurements And Functions
3. Measurements and functions Measured and calculated values Almost all the electric parameters in power systems can be measured by the MIB. Some of the parameters which are special will be described in this part. Reactive power (Q) MIB adopts two definitions of reactive power: 1. - Page 10 In the formula, U is RMS value of the voltage fundamental and U is RMS value of the voltage harmonic with order n. Harmonic parameter : Each harmonic rate The percentage of each harmonic divided by fundamental. Demand Demand of total power and reactive power of system, demand of 3-phase current. The demand statistics method in MIB is sliding windows.

Page 17: Modbus
6. Modbus How it works The MIB is based on a digital processing platform. All current and voltage input signals are digitally sampled and all values are calculated from these sampled signals. The MIB can also measure total harmonic distortion of voltage and current. Measuring principles 6.2.1 Voltage (U) -
Page 18: Reactive Power (Q)
If you use Modbus to collect the power data, you need to use this equation to calculate the power values: where Rx = register value, CT1 and CT2 = current transformer data, and PT1 and PT2 = voltage transformer data. 6.2.4 Reactive power (Q) The MIB calculates the three-phase reactive power and the total reactive power of the system. -
Page 19: Reactive Energy (Eq)
where Rx = register value. 6.2.8 Reactive energy (Eq) The reactive energy is the time integral of reactive power, and the unit is kVArh. Import of reactive energy is equal to inductive reactive energy, and is positive. Export of reactive energy is equal to capacitive reactive energy and is negative. You can see the reactive energy counters on the display. -
Page 20: Total Harmonic Distortion (Thd)
where Rx = register value, CT1 and CT2 = current transformer data, and PT1 and PT2 = voltage transformer data. Apparent power (S) where Rx = register value, CT1 and CT2 = current transformer data, and PT1 and PT2 = voltage transformer data. Current, I1 where Rx = register value, CT1 and CT2 = current transformer data, and PT1 and PT2 = voltage transformer data. -
Page 21: Maximum And Minimum Statistics
You can see the unbalance factors on the display. You can also view the values remotely using RS485 communication and MIBLink, the MIB utility software. If you use Modbus to collect the unbalance factor data, you need to use these equations to calculate the values: where Rx = register value. -

Page 23: End-Of-Life
In Europe, the disposal of WEEE is governed by the WEEE directive issued by the European Parliament. DEIF complies with this directive. You must not dispose of WEEE as unsorted municipal waste. Instead, WEEE must be collected separately, to minimise the load on the environment, and to improve the opportunities to recycle, reuse and/or recover the WEEE.
