Transmission Training
The Timpson Training Yard Panel is a state-of-the-art system that allows line workers to train using the same real-world voltage that they will see every day on the job, while at the same time eliminating the risk of arc-flash. Whether you are learning skills for the first time, or are a trainer that sees the benefits of training your crew safely with full voltage, we can customize your training yard control system, for your yard.


What’s New?

  • Voltages include:
  • 34kV for Hot Sticking
  • 69kV
  • 138kV
  • PROCESSOR SCAN TIMES: Average Scan Time: 1-2 ms/program cycle
  • SAFETY RELAY INFO: SIL 3 Release Time: t
    • Fail Safe I/O: SIL Level 3 (per IEC 61508)
    • Safety Relay (Master) SIL Level 3 (per IEC 62061)
    • SIL Level 3 as above
    • IEC 61508 – Electrical Safety of Electrical/Electronic/Programmable safety related systems
    • IEC 62061 – Safety for Machinery
  • MISC SAFETY INFO: 00001A (10µA) Increments
    • Main Disconnect Handle allows (3) simultaneous Lock-Out-Tag-Out systems;
    • System reset and initialization requires a supervisory key;
    • High-Voltage Energize pushbutton is protected under a pad-lockable safety cover;
    • System Safe/Off pushbutton utilizes redundant normally closed contacts, one of which is Normally Closed Self-Monitoring;
    • E-Stop Pushbuttons utilize SIL3 redundant sets of normally closed contacts, one of which is Normally Closed Self-Monitoring;
    • Master Safety relay can only be reset by inserting the supervisory key and indexing the RESET selector switch to the Safety position – the controller cannot reset the safety relay via program. (The master safety relay must be reset once power is applied to the panel before operation can commence.);
    • Panel doors have coded magnetic door switch with SIL3 redundant N.C. contacts in line with the master safety relay;
    • High-Voltage is physically isolated inside control panel from low voltage.
  • LISTINGS UL 508A Industrial Control Panel

Q: Will Timpson install the system in our training yard?

A: Unfortunately no, Timpson does not possess the capabilities to install our systems throughout the country and/or globally. We can however, work to answer any questions that your installation contactor may have. We also have Bulletin 2300 – Training Yard Installation Manual available for download on our website.

Q: Can Timpson provide us with info on the concrete pad/slab requirements?

A: Timpson cannot provide these requirements as local codes and soil constraints differ from location to location.

Q: What is the environmental rating of the panel?

A: All Training Yard systems are constructed to meet Nema 4 (IP66) requirements. However, some environments will require additional consideration from the Timpson engineers. For instance, extreme heat with temperatures over 104*F for more than a week at a time, and extreme cold with risk of ice build-up, must be brought to our attention prior to ordering.

Q: What is the system capable of energizing in my yard?

A: The system is capable of energizing the lines, and secondary transformers – without load. Basically, only the excitation current of transformers will be recognized at start-up and allowed to become energized. The system is only capable of outputting 30mA of total line current, as a secondary means of safety.

Q: What size concrete pad do I need to set the unit on?

A: Please refer to the “Mounting Pad” section of the Installation Manual (Bulletin 2300)

Q: Where do I bring the conduits up through the concrete pad?

A: Please refer to the “Mounting Pad” section of the Installation Manual (Bulletin 2300)
