Handling this device · To avoid damage to the product, protect it from vibration or shock during transport and handling, and be especially careful to avoid dropping. · Be careful to avoid dropping the clamps or otherwise subjecting them to mechanical shock, which could damage the mating surfaces of the core and adversely affect measurement. 9 Using the clamp-on sensors and voltage cords Connect the clamp-on sensors or voltage cords to the instrument first, and then to the active lines to be measured. Observe the following to avoid electric shock and short circuits. · To avoid short circuits and potentially life-threatening haz- ards, never attach the clamp to a circuit that operates at more than the maximum rated voltage to earth (9660: 300 VAC, 9661: 600 VAC, 9667/CT9667: 1000 VAC, 9669: 600 VAC, 9694: 300 VAC, 9695-02/03: 300 VAC), or over bare conductors. · Clamp sensor and voltage cord should only be connected to the secondary side of a breaker, so the breaker can prevent an accident if a short circuit occurs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs. · Do not allow the voltage cord clips to touch two wires at the same time. Never touch the edge of the metal clips. · Use only the supplied L9438-53 Voltage Cord to connect the product input terminals to the circuit to be tested. · To prevent an electric shock accident, confirm that the white or red portion (insulation layer) inside the cable of voltage cord is not exposed. If a color inside the cable is exposed, do not use the cable. · When the clamp sensor is opened, do not allow the metal part of the clamp to touch any exposed metal or to short across two lines, and do not use over bare conductors. · The current input terminals of the 3169-20/21 are not insulated. To avoid the risk of electric shock, only use the specified optional clamp-on sensor. 10 Handling the cords · Keep in mind that, in some cases, conductors to be measured may be hot. · To avoid damaging the power cord, grasp the plug, not the cord, when unplugging the cord from the power outlet. · To avoid damaging the voltage cords or clamp sensor cables, do not bend or pull near their ends. · Avoid stepping on or pinching the cable, which could damage the cable insulation. · Keep the cables well away from heat sources, as bare conductors could be exposed if the insulation melts. · When disconnecting the BNC connector, be sure to release the lock before pulling off the connector. Forcibly pulling the connector without releasing the lock, or pulling on the cable, can damage the connector. · Failure to fasten the connectors properly may result is sub-specification performance or damage to the equipment. Input Maximum input voltage and maximum rated voltage to earth · The maximum input voltage of the product is 780 Vrms, 1103 V peak. Do not measure the voltage exceeding that. It causes the personal injury as well as damages the product. · The maximum rated voltage to earth of the product is 600 Vrms. Do not measure the voltage to earth exceeding that. It causes the personal injury as well as damages the product. · The maximum rated voltage to earth of clamp sensor depends on the type of clamp sensor used. To avoid electric shock, refer to the instruction manual of a clamp sensor used. 11 · To avoid damage to the product, do not short-circuit the output terminal and do not input voltage to the output terminal. · Voltage input terminals U1, U2, and U3 are common to the N terminal and are not insulated. To avoid the risk of electric shock, do not touch the terminals. · Note that the product may be damaged if current or voltage exceeding the selected measurement range is applied for a long time · When the power is turned off, do not apply voltage or current to the voltage input terminals or clamp sensor. Doing so may damage the product. · To prevent damage to the instrument and sensor, never connect or disconnect a sensor while the power is on, or while the sensor is clamped around a conductor. Using VT(PT) and CT · When the voltage or current for the power line being measured exceeds the maximum input for this device, use an external VT(PT) or CT. · When using an external VT(PT) or CT, make sure you use a device with a minimal phase difference. By setting the VT(PT) or CT ratio, you can read measurement values directly. Measurement values · To ensure measurements are precise, warm up the device for at least 30 minutes after plugging it in. · This device is designed to measure commercial power lines with a frequency of 50 or 60 Hz. It cannot measure power lines of other frequencies or power lines where the waveforms are controlled using an inverter. · This device cannot measure power lines with superposed direct current. · This device uses algorithms to measure values for input voltage and current waveforms using (see the specifications). On devices using different operation principles or algorithms differ, differences in measurement values may result. · The voltage and current measurements will be reduced to zero when inputs are less than 0.4% of the measurement range. When the voltage or current is zero, the active power, reactive power, and apparent power measurements will be reduced to zero and the power factor will be treated as invalid data.

PLL PLL (default) FIXED FIXED Fixed clock * Normally set to PLL Move the cursor to Measured Frequency. 50 Hz Set to the frequency of the line to be measured by using the func60 Hz tion keys. (Default: 50 Hz) What is PLL? PLL stands for "Phase Locked Loop" and is a phase synchroniza- tion circuit. The 3169-20/21 uses PLL to generate a frequency synchronized with the fundamental wave (50/60 Hz) and multiplied by 128, to sample input waveforms of voltage and current. If there is no PLL input (PLL source), there is no means of sampling input waveforms, and calculation cannot be performed. This is called "PLL unlock." When there is no PLL source, the 3169-20/21 switches the synchronization method over to the internal clock (50/ 60 Hz fixed clock). 64 5.2 Setting on the Measurement Setting Screen (MEASUREMENT) 5.2.3 Setting the Reactive-Power-Meter Method (3169-20: SET UP 1/4, 3169-21: SET UP 1/5) Press the SET UP key to display the setting screen.

Because calculation includes the harmonic component, the power factor will decrease as the harmonic current increases. When the reactive-power-meter method is ON (to be used), the power factor is obtained as a cosine of the phase difference between the fundamental voltage and fundamental current. Cal- 5 culation is performed using the fundamental component only, and does not include the harmonic component. 5.2 Setting on the Measurement Setting Screen (MEASUREMENT) 66 5.2 Setting on the Measurement Setting Screen (MEASUREMENT) 5.2.4 Setting the Display Average Times (3169-20: SET UP 1/4, 3169-21: SET UP 1/5) Press the SET UP key to display the setting screen.

In the figure, U1, U2, and U3 represent the vectors of line to line voltage; I1, I2, and I3 represent the line (phase) current vec- tors; u1, u2, and u3 represent the phase to neutral voltage vectors. Normally, three-phase power P is obtained as the sum of the power of the phases. P = u1I1 + u2I2 + u3I3 (1) 204 A three-phase 3-wire line, however, doesn't have a neutral point, and the power of each phase cannot be measured directly. If a neutral point hypothetically existed, three power meters must be used simultaneously. For this reason, the 2-power-meter method (2 voltages and 2 currents) using the line voltage is generally used instead. Theoretically, the power of each phase is obtained using the following equation: If measuring U1, U2, I1, and I3 using power meters, P = U· 1I·1 + U· 2I·3 ( U1= u1- u2, U2= u3- u2 ) = u·1 u·2I·1 + u·3 u·2I·3 = u·1I·1 + u·2I·3 I·1 + u·3I·3 (because I1+ I2+ I3=0 provided that the circuit is closed) = u·1I·1 + u·2I·2 + u·3I·3 (2) Equation (1) coincides with equation (2). This proves that the power of a three-phase 3-wire line is measured by the 2-powermeter method. In addition, there is no special precondition required, except that the circuit must be closed and without leakage current. Therefore, three-phase power can be obtained regardless of whether the cable way is balanced or unbalanced. The 3P3W2M mode of the 3169-20/21 employs this method. In addition, because the sum of the voltage (current) vectors is always zero, the 3169-20/21 internally implements the following equations to measure the 3rd voltage and current: U· 3 = U· 1U· 2 I·2 = I·1 I·3 Regarding U3 and I2, measurement is performed regardless of whether distortion is present. These values are reflected in the three-phase apparent power and power factor (when the reactivepower-meter method is not used). In the 3P3W2M mode of the 3169-20/21, the phase C current of the three-phase line is input to I2 of each circuit. On the display, the current measurement of phase C is shown as I2, and the calculation result of phase B is shown as I3.

Appendix 209 Harmonic Phase Angles The harmonic voltage phase angle and harmonic current phase angle are the standard for the PLL source phase (for input based on PLL when U1 is selected on this device) fundamental wave component. The differences in phase of each harmonic order component and the phase of the fundamental wave component is expressed as an angle (°) and - indicates a LAG, whereas + indicates a LEAD. The phase angle of harmonic power is expressed by the power factor of each order of harmonic converted into an angle (°). When the harmonic-power phase angle is between -90° and +90° , the order of harmonic is flowing in toward the load (inflow). When the phase angle is between +90° and +180° or between -180° and - 90°, that order of harmonic is flowing out from the load (outflow). 90° ±180° Outflow Power Phase Angles LEAD Voltage and current phase Inflow 0° angles LAG -90° Harmonic phase angle The arithmetic expressions for the harmonic-power phase angle vary depending on whether the reactive-power-meter method is ON or OFF. 210 Reactive-Power-Meter Method ON Harmonic-power phase angle = tan-1 Q P [°] Both active power and reactive power have polarities, and the results are expressed by "0° to 180°". This enables identification of inflow and outflow and lag (-) and lead (+). Reactive-Power-Meter Method OFF Harmonic-power phase angle = cos-1PS [°] Active power has polarities, but apparent power does not. The results are expressed by "0° to +180°". Identification of inflow and outflow is possible, but that of lag (-) and lead (+) is not. Due to the difference in arithmetic expression, the harmonic-power phase angle may differ if the three-phase load is unbalanced. Appendix 211 Output Data How to calculate the average value. (AVE) The average values of voltage, current, active power, reactive power, apparent power, power factor, and frequency are calculated by the following formulas. Voltage U _ AVE 1 N 1 Un N n0 The voltage RMS values for every one cycle are averaged within the interval period. Current I _ AVE 1 N 1 In N n0 The current RMS values for every one cycle are averaged within the interval period. Active Power P_ AVE 1 N N 1 Pn n0 The active power values for every one cycle are averaged within the interval period. (including the polarity sign) Reactive Power Q_ AVE si 1 N 1 Qn N n0 The absolute values of reactive power for every one cycle are averaged within the interval period. When the reactive-power-meter method is OFF(not to be used), there is no polarity sign to reactive power value. Apparent Power S _ AVE 1 N 1 Sn N n0 The apparent power values for every one cycle are averaged within the interval period. 212 Power Factor PF _ AVE si 1 N N 1 PFn n0 The absolute values of power factor for every one cycle are averaged within the interval period. Frequency F _ AVE 1 N 1 Fn N n0 The frequency values for every one cycle are averaged within the interval period. N : The number of the data in the interval period Un : The voltage RMS value of every one cycle In : The current RMS value of every one cycle Pn : The active power value of every one cycle Qn : The reactive power value of every one cycle Sn : The apparent power value of every one cycle PFn : The power factor value of every one cycle Fn : The frequency value of every one cycle si : Polarity of lead or lag (lag: no indication, lead: -) By assuming when Qn 0, Q ; or when Qn < 0, Q'; No indication for si when Q |Q'| in the interval period. "-" is indicated for si when Q < |Q'|.
