Failsafe software has been installed to Spamgon without issue.
The failsafe software creates pop-up messages when a piece of code is run on Spamgon. These will pop-up under three circumstances; action override, biological override, or pain override. For example, if someone were to hit Spamgon (please do not), the pain override failsafe would not activate. He would feel pain as normal. Failsafes can only be triggered by running code directly on Spamgon. There are workarounds, and it is not perfect. But for the purpose of double checking each and every function I personally run on him, this will work.
The process of testing the failsafe was tedious. For each type of override, I ran a small piece of code that should trigger a pop-up. I had Spamgon relay the pop-up to me, then deny it. This then repeated, but instead he accepted it. For the action override, his spun slowly for a few seconds, and the pop-up would read for him as "functional override, rotation of head segment, 5 rpm, proceed?". For the biological override, his left arm segment would turn green for a few seconds, displaying the pop-up "biological override, recolor left arm segment, hex value #3d8c40, duration 3 seconds, proceed?" For the pain override, a small shock would be delivered to his right arm segment, displaying the pop-up "pain override, shock to right arm segment, 5 kV, proceed?" We also repeated with a faster rpm, a different hex value, and a lower voltage to ensure the readings on the pop-up were correct.
The failsafe appears successful, however I will be staying here overnight and asking that he stays in the lab as well, in case there are any issues.
I do... feel bad about testing the pain override. The shocks were at such a low voltage that it should be no more than a carpet shock from static electricity, but it made him jump. Spamgon appeared uncomfortable when I asked him to select "yes" for the pop-up. In the long term, I know this is important. If there is ever more significant pain caused by running code, we know the failsafe will trigger and stop it before it happens. I still can not help but feel terrible. Watching him jump at the sudden shock, it felt cruel. Maybe there was a way to save him the pain. Maybe I should have tried harder.
He is putting his trust into me, and I am fearful it may all come crashing down. I hope this works. For his sake, I will do everything I can.

High voltage commissioning is a crucial step in ensuring the safe and efficient operation of electrical systems
High voltage commissioning is one of the most critical phases in the lifecycle of electrical systems, laying the groundwork for their safe and efficient operation. As modern industries increasingly rely on robust electrical infrastructure, proper commissioning becomes essential to mitigate risks and enhance performance. This process involves a series of systematic tests and inspections to ensure that high voltage equipment functions as intended, adheres to safety regulations, and meets operational standards.
Understanding High Voltage Commissioning
High voltage commissioning is the entire process that is carried out when new electrical installations, such as switches, transformers, and cabling systems, are connected to the power grid. This process is multifaceted, covering the verification of installations, electrical earthing system, system configurations, and safety protocols. Each step in commissioning serves to validate that the equipment will operate effectively within its designated parameters.
Key Aspects of High Voltage Commissioning
1. Visual and Physical Inspection A visual inspection is conducted before any electrical testing can be done. This inspection checks the quality of installation, mechanical integrity, and adherence to design specifications.
2. High Voltage Cable Testing: One of the major parts of a commissioning activity is the testing of high voltage cables. These tests include insulation resistance testing, which tests the integrity of the insulation material; megger testing, where the insulated part of a cable is applied with high voltage to detect any faults; and high potential, or hi-pot, tests to ensure that the cable can withstand operational voltages.
3. Functional Testing. After cable testing, functional testing is performed on all elements of the system-the circuit breakers, protective relays, and control systems-by confirming that every element works correctly with other parts of the electrical system.
4. Verification of Electrical Earthing System: In high voltage installations, the electrical earthing system is an essential safety measure. It ensures that fault currents have a direct path to the earth and hence prevents electrical shocks and equipment damage. In commissioning, the earthing system should be tested for resistance and functionality to ensure it will perform as needed during low-resistance fault conditions.
5. Performance Testing: After individual components are tested, performance testing is implemented to evaluate the entire system's behavior under various operational scenarios. This may include load testing, which simulates real operating conditions, and transient analysis to assess the system's response to sudden changes in load.
Importance of High Voltage Maintenance
High voltage maintenance is of utmost importance after successful commissioning to maintain the safety and efficiency of electrical systems. Regular maintenance, which includes inspections, testing, and repairs, ensures that equipment remains in optimal condition. Preventive maintenance, coupled with predictive analytics, can identify issues before they lead to system failures, thus safeguarding investment and enhancing reliability.
Moreover, continued maintenance supports the high voltage commissioning work as it ensures that the initial testing and verification processes are maintained throughout the lifetime of the facility. Higher efficiency can reduce operational costs and increase system life.
High voltage commissioning is not a mere regulatory checkbox. It is the process that guarantees the integrity, reliability, and safety of electrical systems. From rigorous cable testing to the validation of electrical earthing systems, every step of the commissioning process is essential to ensure high voltage installations perform as expected.
As technology advances, and the need for efficient energy systems continues to grow, a strong commissioning and maintenance approach will be necessary. It is essential for companies to consider these processes so that they are able to protect their assets, as well as those who may work with or around high voltage equipment. Finally, investing in thorough commissioning and reliable on-going maintenance means that not only will safety standards be met but also that it will open doors to sustainable energy management in this modern world.
