SQ0214 SYNCHROSCOPE, Synchronization Meter. Used, Fresh & Good Condition. Price:- Negotiable.

Product Detail of SQ0214 SYNCHROSCOPE

The SQ0214 is a microprocessor-based synchronization meter (synchroscope).
It allows operators to carry out manual as well as semi-automatic synchronization of a generator with a bus-bar system.
To do this, the instrument continuously measures phase difference, voltage, and frequency; therefore, the operator can connect the generator to the network safely and at the correct moment.

Moreover, Iskra manufactures the unit specifically for industrial and marine power applications.

Key Technical Specifications of SQ0214 SYNCHROSCOPE

Measurement Capabilities

The SQ0214 combines five measuring instruments into a single device.
In particular, it replaces:

• two voltmeters,

• two frequency meters,

• and one phase-difference meter.

As a result, the user reduces panel space, wiring complexity, and installation cost.
Additionally, maintenance becomes easier because technicians service only one instrument instead of several separate meters.

Display System

LED Circular Display

First, a 24-LED circular ring indicates the instantaneous phase difference (Δϕ).
Normally, each LED represents 20°.
However, when the phase angle enters the synchronizing window (±15°), the instrument automatically increases the resolution to 5°.

Consequently, the operator can immediately determine whether the generator runs faster or slower than the bus-bar.
At the same time, the LED rotation direction visually shows the frequency difference.

Backlit LCD Display

In addition, the backlit LCD displays multiple electrical parameters simultaneously:

• Generator voltage (UGEN)

• Bus-bar voltage (UBB)

• Generator frequency (fGEN)

• Bus-bar frequency (fBB)

• or phase difference (Δϕ)

Therefore, the operator no longer requires separate measuring meters.
Furthermore, the backlight improves readability in low-light control rooms and engine rooms.

Adjustment Settings of SQ0214 SYNCHROSCOPE

On the rear panel, adjustable potentiometers allow the operator to define synchronization limits.
Specifically, the user can set:

• Phase Difference (Δϕ): typically 2°–20°

• Voltage Difference (ΔU): typically 1%–10%

• Delay Time (DELAY): typically 0.1–1 s

Accordingly, technicians can adapt the device to both small standby generators and large power plant alternators.
Thus, the same model works in many different installations.

Operating Range

Depending on the model, the instrument supports:

• 40–70 Hz, or

• 45–65 Hz.

Therefore, the SQ0214 operates reliably in both 50 Hz and 60 Hz systems.
In other words, engineers can use it in most international power networks.

Core Functionality

Synchronization Relay

When phase angle, voltage difference, and delay settings fall within preset limits, the internal relay activates.
Then, the relay sends the circuit-breaker closing command exactly at the synchronizing point.

The user may configure the relay for:

• pulse output, or

• continuous output.

Hence, the generator connects only under correct electrical conditions, and consequently the system avoids mechanical and electrical stress.

Dead Bus-Bar Function

Furthermore, the SQ0214 includes a dead bus-bar synchronization feature.
This function allows connection when the generator is live but the bus-bar remains de-energized.
Typically, the user sets the detection threshold between 10% and 40% of nominal voltage.

As a result, operators can start a plant from blackout conditions.
Therefore, the device becomes especially useful during plant commissioning and black-start procedures.

Status Monitoring Output

The instrument also provides an open-collector status output.
Under normal conditions, the output stays in a low-impedance state.
However, if the microprocessor detects a fault, it switches to high impedance.

Consequently, external alarms, PLCs, or monitoring systems can immediately identify a malfunction and take protective action.

Safety & Compliance

The SQ0214 satisfies industrial installation requirements.
Specifically, it meets:

• Installation Category III

• Pollution Degree 2

• CE compliance

• Marine approvals (e.g., Bureau Veritas)

Accordingly, engineers commonly install the unit in ships, generator control panels, and power stations.

Mechanical Construction

Finally, the manufacturer supplies the device in standard DIN panel housings:

• 96 × 96 mm

• 144 × 144 mm

Because of these standard sizes, technicians can easily mount, replace, or retrofit the instrument into existing panels.

Summary of SQ0214 SYNCHROSCOPE

In summary, the Iskra SQ0214 Synchroscope integrates measurement, synchronization control, monitoring, and operator guidance into a single compact unit.
Therefore, it increases synchronization accuracy, reduces operator error, and protects generators as well as connected equipment.
