CURRENT TRANSFORMER

Current transformers are used for monitoring load current in networks or great loads. They transform currents in the kA range to e.g. 0-1 A or 0-5 A. Thus large load currents can be evaluated and monitored by downstream automation devices. The new “PACT” analog current transformer portfolio offers a complete range of tubular bar, plug-on and wire-wrap transformers for measuring large currents of 1 A to 4000 A. Depending on the application requirements, almost 3000 different versions of different accuracy classes, capacities and sizes are available. Different mounting positions allow for use even in applications where space is critical.

Besides non-calibratable current X’mers, calibratable X’mers are offered, which become calibrated current X’mers after an additional calibrating process. On customer’ request, the calibration of the measuring transducers including the creation and handling over of all certificates can be processed by Phoenix Contact.

Typical Application

Creating Standard Signals

Control systems or display elements Like e.g. digital display require standard signals of e. g. 0…20mA as an input signal. As in the current application path to be measured, large currents of upto 4000 A can occur, you need current X’mers that convert these high current to 1 A AC or 5 A AC. Then downstream current transducers uses this current to create typical standards signals that can be processed by e.g. control system.

Current Monitoring:

With the help of monitoring relays (IF monitoring), currents can be monitored and over currents can be can be signaled via a switching output. As typical monitoring relays only have a measuring input of up to 10 A maximum, a current X’mers the high currents into smaller ones.

Motor Management :

The electronic motor managers (EMMs), among other things, serve for motoring a drive system or a 3 – phase load. For this, 3 currents have to be measured and monitored. Currents of more than 5 A cannot be processed by the EMM current measuring input. Therefore, separate current X’mers has to be installed before the current measuring input so that the primary current is transformed into 5 A maximum.

Test Circuits :

Test disconnect terminal blocks and slide terminal blocks were developed especially for the use in current X’mer secondary circuits. The terminals can be fitted on both sides with fixed and switchable jumpers as well as test sockets.

   

The advantages of Current transformer

  • Different mounting positions possible (e.g. Flat on a copper rail >> mounted with zero spacing >> particularly space saving)
  • Small housings for all current transformers of 30mm
  • Simple handling
  • In addition to non-calibratable current transformer, calibratable and calibrated transformers with certificate are offered.
  • Broad product range (almost 3,000 versions)
  • One-stop shopping >> current transformers, measuring transducers, monitoring modules, load relays, knife disconnect and disconnect terminal blocks.

ELECTRONIC MONITORING DEVICES (EMD SERIES)

Processes are becoming more and more complex, thus safety aspect plays a large role here. It is therefore important to have measurement and control monitoring of drives in modern switchgear and control gear systems. The range from Phoenix Contact covers voltage and current monitoring for single phase and three phase networks and for consumers and controllers.
Requirements pertaining to safety and system availability increase constantly regardless of the sector. Processes are becoming more and more complex, not only in the mechanical engineering and chemical industry but also in plant automation technology. Demands on power engineering are also constantly on the raise.
Trouble free and therefore cost-effective operation can be achieved only with continuous monitoring of significant network and system parameters. Electronic monitoring relays of the EMD series are available for the widest varieties of monitoring tasks avoid consequences of errors or to keep them within times. The operating states are singled using colored LEDs and the errors that may occur can be sent to a controller through a potential-free contact or can shut down a section of the system. Some device versions are equipped with startup and response delays in order to briefly tolerate measured values outside the fixed monitoring range.

Monitoring Relay : The monitoring modules of the EMD series offer a cost-effective solution for the monitoring task such as current, voltage, Phase parameters, coil temperature, motor load and fluid level

Timer Relay : A practical combination of functions and time setting ranges as well as devices with special functions (Star-Delta) are available for the timer relays of the ETD series.

Function Blocks : In the function blocks, simple functions down to the component level are packaged for industrial use and provided with professional connection methods.

Full Product Range :

  • Single - Phase Power monitoring
  • Single – Phase Voltage monitoring
  • Three – Phase Voltage monitoring (Incl. Phase monitoring)
  • Phase sequence monitoring
  • Thermistor monitoring
  • Voltage indication modules
  • Load Monitoring
  • Filling level monitoring

Advantages of using Electronic Monitoring Devices:

  • Frequency range from 16.67 up to 400 Hz.
  • Under or over voltage or over current detection.
  • Phase sequence, phase failure and asymmetry recognition.
