iFlex Current Probe

The iFlex Current Probe works on the Rogowski coil (Rcoil) principle that is a toroid of wire used to measure an alternating current through a wire encircled by the toroid. See Figure 2.

hcf028.eps

The R-coil has many advantages over other types of current transformers:

• It is not a closed loop. The second terminal is passed

back through the center of the toroid core (commonly a plastic or rubber tube) and connected along the first terminal. This allows the coil to be open-ended, flexible, and able to be wrapped around a live conductor without disturbing it.

• It has an air core rather than an iron core. It has a low

inductance and can respond to fast-changing currents.

• Because it has no iron core to saturate, it is highly

linear even when subjected to large currents, such as those used in electric power transmission or pulsedpower applications.

A correctly formed R-coil, with equally spaced windings, is largely immune to electromagnetic interference.

Kensington Lock

A Kensington Security Slot (also called a K-Slot or Kensington lock) is part of a built-in anti-theft system. It is a small, metal-reinforced, oval hole found on the right side of the Monitor (see item 6 in Table 3). It is used for attaching a lock-and-cable apparatus. The lock is secured in place with a key or combination lock attached to a plastic-cover metal cable. The end of the cable has a small loop that allows the cable to be looped around a permanent object, such as a cabinet door, to secure it in place. This lock is available from most electronics and computer suppliers.

Load Study (no voltage measurement)

Nominal Voltage (only in load studies)

Select a nominal voltage from the list. If a voltage is not shown in the list, enter a custom voltage. Use the nominal voltage on load studies to calculate the pseudo apparent power:

nominal voltage × measured current

Set the nominal voltage to off if the apparent power readings are not required.

Voltage Ratio (only in energy studies)

Configure a ratio factor for the voltage inputs when a potential transformer (PT) is in series with the voltage connections such as when you want to monitor a mediumvoltage network. The default value is 1:1.

Nominal Frequency

Set the nominal frequency to be the same as the power line frequency, 50 Hz or 60 Hz.

Use  (Show Menu) to navigate between the subscreens.

Current Range

Configure the current range of the attached sensor. Three ranges are available:

• Auto

• Low Range

• High Range

When set to Auto, the current range is set automatically and depends on the measured current.

3540 FC

Users Manual

Low Range is 1/10 of the nominal range of the attached current sensor. For example, the low range of an iFlex1500-12 is 150 A.

High Range is the nominal range of the attached current sensor. For example, 1500 A is the nominal range on an iFlex1500-12.

Note

Set the current range to Auto when you are not sure about the maximum current during the logging session. A specific application can require you to set the current range to a fixed range rather than Auto. This can occur because the Auto range is not gapless and may lose too much information in the case of a highly fluctuating current.

Current Ratio

Configure a ratio factor for the current sensors when you use a current transducer (CT) to measure the much higher level on the primary side at a substation or step-down transformer that has a built-in metering current transformer.

The current ratio can be used to increase the sensitivity of the iFlex sensor. Wrap the iFlex sensor around the primary conductor, for example 2X, and enter a ratio factor of 1:2 to get correct readings. The default value is 1:1.

Connection Verification and Correction

Once the measurement is configured and the voltage and current inputs are connected to the system under test, go back to the Meter mode and use the Verify Connection touch button to confirm the connection.

The verification detects:

• Signal is too low

• Phase rotation for voltage and current

• Inverted current probes

• Wrong phase map

In the connection verification screen:

1. Push  to toggle between Generator Mode and Load Mode.

Usually the current flow direction is toward the load. Use Load Mode for these applications. Use the Generator Mode when the current sensors are connected intentionally to the generator (for example, during the time energy goes into the grid from regenerative braking system of an elevator or on-site wind turbines).

The current flow arrow indicates the correct flow: a normal condition is shown in Load Mode with a black arrow pointing upwards, in Generator Mode the black arrow points downwards. If the arrow is shown in red, the current flow direction is inverted.

3 Phase Power Monitor

Function Selection Buttons

2. Push  (Correct Digitally) to access the connection correction screen. Use this screen to virtually swap phases and invert the current inputs instead of a manual correction.

3. If the Monitor is able to determine a better phase map or polarity, push  (Auto Correct) to apply the new settings.

Auto Correct is not available if the algorithm is not able to detect a better phase map or when no errors are detected.

Note

It is impossible to detect all incorrect hook-ups automatically. You must verify the suggested modifications carefully before you apply the digital correction. Applications with single-phase energy generation can deliver the wrong results when you apply the Auto Correct feature.

The algorithm works in a way that creates in three phase systems a sequence with a clockwise phase rotation.

Power

 – In the Power mode you can get the values and a live trend chart for each phase (A, B, C or L1, L2, L3) and total as:

• Active Power (P) in W

• Apparent Power (S) in VA

• Non-active Power (N) in var

• Power Factor (PF)

Use  (Fundamental/RMS) to toggle between full bandwidth power values and power of the fundamental.
