Electrical and control systems

What are the electrical and control systems of a stage and what do we check?

Our inspection and service activities cover complete high- and low-current distribution systems and all control electronics used in a theatrical environment. We regularly service and revise:

• Central control panels and mobile controllers for operating stage mechanization,
• Switchboard and distribution board systems (power, control, socket and motor switchboards),
• Frequency converters and servo drives for continuous speed and travel control of drives,
• Safety circuits and emergency stop systems (CENTRAL / TOTAL STOP),
• Programmable logic relays and safety PLCs,
• Sensors and sensors (limit switches, optical barrier systems, encoders, overload and position sensors),
• Supply cable routes, energy chains and flexible stage power supplies.

Electrical equipment on stages is exposed to frequent switching, vibrations and high current loads. A failure of the control system or a hidden defect in the electrical installation can cause uncontrolled movement of the equipment, loss of performance or even the risk of injury and fire. Regular inspection of electrical equipment is therefore a fundamental condition for safe operation.

Our services: Complete inspection, maintenance and service of control electronics

At TECHARTSTAV we approach stage electrical engineering with maximum expertise. Whether you are managing older relay systems or the most modern fully automated stage control, we will ensure their reliable functionality.

1. Regular statutory inspections of dedicated electrical equipment

We perform certified periodic inspections of electrical installations and control systems in accordance with applicable Czech legislation and relevant ČSN standards. The output of our work is an official electrical inspection report, which serves as a legal document for state professional supervision bodies, insurance companies and the final approval procedure.

The inspection includes:

• Measurement of insulation resistance, fault loop impedance and continuity of protective conductors,
• Testing the functionality of residual current devices, circuit breakers and overcurrent protection,
• Checking safety circuits, emergency STOP buttons and blocking systems,
• Thermal imaging inspection of switchboards aimed at revealing overheating connections and components,
• Checking the condition of cable routes, movable leads and their mechanical covering.

2. Preventive service and diagnostics of drives

Prevent unplanned scene outages. Our preventive service of control systems includes cleaning switchboards from dust, tightening terminal connections, checking the cooling of converters, calibrating position sensors and backing up control programs (PLC).

3. Quick repairs and troubleshooting

We react promptly in the event of a control failure. We perform repairs of stage electronics, replacements of defective contactors, sensors, converters or worn cable connections. Thanks to our own facilities and diagnostic tools, we can precisely locate the fault and eliminate it in the shortest possible time.

4. Modernization and software upgrade of control

Outdated relay boxes or unavailable spare parts? We will modernize the stage control system. We will replace old controls with modern touch panels, safety PLCs and frequency converters for quiet, smooth and safe operation of the entire scene.

Why choose TECHARTSTAV for electrical installation and control services?

• Specialization in stage technology: We not only understand common electrical installations, but also know the specifics of theatrical standards, safety categories and the behavior of drives on stage.
• A comprehensive view of the system: We combine knowledge of electrical engineering with mechanical elements. We know exactly how electronics affect the behavior of motors, brakes and mechanical connections.
• Maximum emphasis on safety: We strictly adhere to the ČSN EN standards regarding electrical equipment of machine and safety circuits.
• Adaptation to your operation: We plan inspection and service work so that they do not disrupt the testing process or the schedule of planned performances.

How does cooperation work?
