Chapter 5 Measurement performance
5.1 Voltage
For EGO700 voltage measurement, the maximum direct-connected phase
voltage is 400V, and line voltage is 500V. The user should pay attention to this when
designing to prevent saturation of the internal measurement loop, resulting in
inaccurate measurement and even damage to the meter. Higher voltage needs to be
connected through PT. The meter can set PT ratio, and the maximum measurable
phase voltage on the primary side is 650kV. The voltage connection mode can be set
through the panel or communication, and supports star and delta modes.
5.2 Current
EGO700 must use CT to measure current. The secondary rated output of CT
needs to meet the rated current input requirement of EGO700 (5A). When wiring the
external CT, prevent the CT output from being open, otherwise a higher voltage will
be generated in the secondary under the action of the primary excitation, causing
personal injury or death or equipment damage.
The direct access current of EGO700 current measurement channel is 0~6.5A,
and the theoretical maximum measurement current of CT primary side is 500000A.
The user should pay attention to this point when designing to prevent saturation of the

internal measurement loop, resulting in inaccurate measurement.
5.3 Frequency
When EGO700 works in different measurement modes, the acquisition channels
of frequency measurement are different. In the triangle mode, EGO700 measures
frequency through the AB line voltage channel by default; in other modes, EGO700
measures frequency through the A phase voltage channel. If phase A lacks phase,
phase B is selected. If phase A and phase B are missing, take phase C.
5.4 Demand parameters
5.4.1 Real-time demand
Real-time demand is the value of accumulated electrical parameters divided by
the length of time in a time period.
EGO700 provides two demand calculation modes: fixed mode and slip mode. In
any mode, the demand period can be set (5 minutes, 10 minutes, 15 minutes, 30
minutes, 60 minutes). In the fixed mode, the slip time is meaningless; in the slip mode,
the slip time can be set (1 minute, 2 minutes, 3 minutes, 4 minutes), but it needs to
meet the requirement that "the demand period is 5 of the slip time The relationship of
integer multiple of "is shown in the following table.
EGO700 provides three-phase current, three-phase active power, total active
power demand calculation for a total of 7 electrical parameters, and maximum
demand records. The demand value can be viewed through display or communication,
and the demand maximum value record clearing operation is provided.
The following figure shows the calculation method of the demand fixed mode:

5.4.2 Maximum daily demand
EGO700 provides the function of the maximum amount needed, can record the
most value of the amount needed on that day, can obtain through communication.
Once the time crosses the day, the maximum daily demand of the previous day will be
cleared 0.
5.4.3 Maximum monthly demand
EGO700 provides month maximum demand function, can record the demand of
that month the most value, can obtain through communication. Once the time crosses
the month, the maximum monthly demand of the last month will be cleared 0.
5.5 Electric energy
The active and reactive input and output power of EGO700 can accumulate up to
99999999.9kWh, and display one decimal place. When the accumulation reaches the
highest value, it will automatically flip.
5.6 History of electricity energy
EGO700 provides the historical electric energy of the latest 31 days, the
historical electric energy of the last 12 months and the historical electric energy of the
latest 10 years. The data saved is the total active electric energy.
5.7 Harmonic
EGO700 can measure the complete 63 times voltage and current harmonics and
their total harmonic content THD, total even harmonic content TEHD and total odd
harmonic TOHD. The harmonic data is given according to the percentage data of the
fundamental wave, with a decimal number, that is, the value of the fundamental wave
is fixed as 1000, which means it accounts for 100.0% of the effective value of the
fundamental wave, and the rest!
Total harmonic content THD refers to the sum of the higher harmonics except the
fundamental wave,press the following formula to calculate

5.8 Unbalance
In an ideal three-phase power supply system, the ABC three-phase voltage and
current amplitude are equal, and the phase difference is 120°, and it is in a balanced
state at this time. When the actual system deviates from the above situation, the
problem of imbalance and the corresponding reduction of power utilization efficiency
will occur.
EGO700 can measure the positive sequence, negative sequence and zero
sequence amplitude of voltage and current, and calculate and analyze the voltage and
current imbalance.
The voltage and current unbalance calculation formula is as follows:
Voltage unbalance=(Negative sequence component of voltage/Positive sequence
component of voltage)x100%
Current unbalance = (current negative sequence component/current positive sequence
component) x 100%

5.9 Fixed value alarm
The fixed value alarm parameters of the EGO700 device can be set by the host
computer software through communication. When an alarm event occurs, the alarm
type can be read through communication. There are 22 groups of monitored alarm
objects, and each group of parameters includes the following:
(1) Action mode: on/off.
When this monitoring is enabled, the alarm object will monitor and alarm.
(2) Action value: the action value and return value of the over-limit trigger.
For the upper limit, when the measured value is greater than the action value,
takes action, and when the measured value is less than the action value, returns;
For the lower limit, when the measured value is less than the action value, takes
action,, and when it is greater than the action value, returns;
(3) Action delay time: the time to delay action after the limit is exceeded.
The setting range of the action delay time is 0~120s.
Monitoring and alarm objects include: A-phase voltage upper limit, B-phase
voltage upper limit, C-phase voltage upper limit, A-phase voltage lower limit,

B-phase voltage lower limit, C-phase voltage lower limit, phase loss, A-phase current
upper limit, B-phase current upper limit, C-phase Current upper limit, A phase current
lower limit, B phase current lower limit, C phase current lower limit, total active
power upper limit, frequency upper limit, frequency lower limit, residual current
upper limit, first circuit temperature upper limit, second circuit temperature upper
limit, third circuit temperature upper limit , The fourth circuit temperature upper limit,
DI is disconnected.
When the monitoring object meets the action conditions, it also needs to meet the
time regulation to be truly activated. During the entire delay period, if the monitored
object returns within the limit, the monitoring alarm will not be activated. The unit of
action delay is second, and the value range is 0～120. Setting 0 means that once the
monitored object exceeds the limit, the alarm channel will be activated immediately.
For example: Monitor the upper limit of the A phase voltage and the lower limit
of the A phase voltage at the same time. If the voltage exceeds 120% of the rated
voltage for 5 seconds, an alarm is required, and if the voltage is lower than 80% of the
rated voltage for 3 seconds, an alarm is required. The settings are as follows:
Setting Items
Value

A - phase voltage upper limit action value

Action time of A phase voltage upper limit
5s
The action mode of A phase voltage lower limit
open
The action value of A phase voltage lower limit
80
A - phase voltage off-line action time

The figure below describes the above and below situations . The rated voltage is
220V, the upper limit is set at 120% of the rated voltage, the upper limit alarm value is
264V, and the lower limit is set at 80% of the rated voltage, and the lower limit is
176V. When the A-phase voltage value continues to be larger than the upper limit 5s,
the alarm is triggered, and the alarm is immediately cancelled when it is lower than
the upper limit. When the A-phase voltage value continues to be lower than the lower
limit 3s, the alarm will be immediately cancelled.

5.10 Phase sequence adjustment
5.10.1 Manual phase sequence adjustment
The user can adjust the phase sequence of the current channel corresponding to
the voltage channel according to the field wiring;
5.10.2 Automatic phase sequence adjustment
The phase sequence can be adjusted automatically by one-key operation through
the meter interface.
[Note] The automatic phase sequence adjustment needs to meet the following
conditions: Under normal working conditions, the wiring mode is three-phase
three-wire mode and the A/B/C three-phase power factor is greater than 0.8;
