| Franklin DVAF | Medium Voltage | Transformer Hi Pot | Using a Variac and Hi Pot tester, low voltage is converted to very high voltage (therefore very low current) to the medium voltage transformer as a stress test of the electrical insulation. The transformer is moved into the test cell. Power leads are attached, then a safety barrier is placed around the transformer. The tester uses the variac to slowly bring the voltage up to the levels defined in the work instruction for the transformer being tested. | View JHA |
| Waukegan | Field Service - Medium Voltage Commissioning | Customer Site | 1. Site Integration & Safety Overwatch Upon arrival, the Yaskawa Field Service Associate (FSA) will conduct a safety briefing with the designated Customer Representative. Competency: The Representative must be fully briefed on the specific hazards of Medium Voltage (MV) commissioning. The "Shadow" Protocol: The Representative must maintain constant visual contact with the FSA. If the Representative is distracted or must leave the area for any reason, a Safety Stop is mandatory. Work remains suspended until the "Shadow" protocol is restored. Emergency Response: The Representative’s primary responsibility is to serve as the emergency communication link to site medical or fire services. 2. Environmental & Work Area Assessment Before initiating technical work, the FSA shall perform a dynamic risk assessment of the immediate environment, identifying hazards such as: Inadequate lighting or egress paths. Environmental contaminants (moisture, conductive dust). Presence of unauthorized personnel within the Limited Approach Boundary. 3. Energy Isolation & Zero-Voltage Verification Though the unit is pre-installed, the FSA assumes a "Trust but Verify" stance regarding energy control: Group Lockout: The FSA must apply a personal lockout device to the customer’s group clasp. PPE Requirements: High-voltage PPE must be donned based on the site-specific Arc Flash label. In the absence of a label, PPE selection must default to the applicable NFPA 70E Tables. Live-Dead-Live Test: The FSA will verify the absence of voltage on all incoming and outgoing points to ensure the drive is in a "Electrically Safe Work Condition." 4. Technical Inspection & Verification With the drive isolated, the FSA performs a comprehensive audit of the third-party contractor’s work: Inspection of all line-side and load-side terminations. Verification of control wiring, grounding integrity, and torque specifications. 5. Re-Energization & Commissioning Once wiring integrity is confirmed, the LOTO devices are removed in coordination with the customer. Initial Power-Up: Power is applied to the MV drive. Parameterization: Customer-specific operational parameters and safety limits are programmed into the drive logic. Validation: The FSA conducts functional testing to ensure the drive operates within the customer’s specific performance envelopes. Conclusion: Commissioning is deemed complete only after the drive demonstrates stable operation and the customer formally accepts the performance verification. | View JHA |
| Waukegan | Field Service - PhotoVoltaic | Field Service | A photovoltaic drive in the field may have multiple power inputs, all supplied by the customer, and can be in difficult to reach areas. Prior to dispatching a Yaskawa Field Service Engineer, the customer must provide a one-line drawing to Yaskawa service department. The assigned engineer will review this document. The customer is responsible for locking power out to the Yaskawa drive prior to the engineer arriving on site. The Yaskawa engineer will assume the equipment is energized until a zero energy state has been achieved and verified. The customer shall provide a knowledgeable representative who understands the customer unique system architecture. This representative shall remain outside shock and arc flash boundaries at all times when the drive is not in a verified zero energy state. The customer representative's primary purpose during the service activity is to monitor the Yaskawa engineer's work and to call for emergency services if necessary. If the customer representative leaves visual view of the Yaskawa engineer, is on the phone, or is otherwise distracted, service shall be suspended until the customer representative can resume their role. After verifying absence of energy, the Yaskawa engineer performs zero energy troubleshooting. If the problem cannot be isolated and corrected, the engineer dons the required PPE as defined on the NFPA incident energy label or NFPA 70E tables in absence of the label. Troubleshooting with live exposed conductors shall only be conducted in required PPE. | View JHA |
