VisualPhase basic is an easily operated phase comparator, dual phase voltage detector and maintenance tester. Its automatic, thorough self-test ensures reliable function. The permanently enabled interface-testers warn against defect interfaces, whereas a dot matrix display shows the measured current [I/µA] or frequency [f/Hz]. Thanks to the integrated configuration menu it can be adjusted to switchgears operated below nominal voltage on-site, independently for both channels.
The integrated “Universal Phase Comparator” can compare two different interface signals, even if they are of different interface types or voltages. A unique error control avoids switching errors caused by erratic or unfeasible phase comparison. The digital display of phase angle helps to sync different net segments or to put the phase sequence in desired order.
Application and technique
The VisualPhase is a dual phase VDS (Voltage Detecting System) with integrated UPC (Universal Phase Comparator) for the LR-System in compliance with IEC/EN 61243-5 (DIN VDE 0682 T415). Additionally the device connects to HR, MR and LRM string parts with the appropriate adapter.
The evaluated indication of the interface current is executed by means of two bright LEDs per phase, which display the conditions voltage absent, residual voltage, voltage present, string part Ok and high current respectively. Additionally you can read the digital ammeter to get the live interface current in [I/µA] for each phase:
| Condition | Current (Uo = Un) | Display |
|---|---|---|
| Voltage absent | < 0,3 µA | Green continuous light |
| Residual voltage | 0,3 - 2,3 µA | Green flashing light |
| Voltage present | 2,4 - 3,1 µA | Red flashing light |
| String part ok | > 3,2 µA | Red continuous light |
The determination is accomplished with an rms-value measuring method independent of the applied waveform. If operating / nominal voltage differ (the ratio is set), the threshold values will be readjusted accordingly, thus stepper motors, switching power supplies or switchgears with lowered operating voltage pose no threat.
The build-in ampere and frequency meter assists in compliant maintenance-testing of switchgears, as stated in section 5.26 of IEC/EN 61243-5, by providing explicit information via the dot matrix display:
| Display | Meaning |
|---|---|
 |
High current (equivalent to > 120% Un) |
 |
String part ok |
 |
String part defect |
 |
Measured current L1, here 3,2 µA |
 |
Measured frequency L1, here 50 Hz |
Alternatively the multi-functional display can show phase difference φ and its analysis. Fast zero-crossing detectors with digital offset compensation carry out phase comparison:
| Display | Meaning |
|---|---|
 |
Phase difference, here -120° |
 |
Phase balance |
 |
Phase unbalance |
The integrated self-test ensures unfailing operation. It starts automatically whenever the device is switched on. You merely plug the connection leads into the test jacks of the device, push the power button once and the device checks the connection leads, the LEDs, the battery and the correct functioning of electronic measuring circuits and software. If an error is detected you will be notified of fault condition by ticker before it shuts down.
