How to Commission Diesel Generator Before Use?     Commissioning diesel generator before use is crucial. It helps identify potential safety hazards, ensures secure wiring connections to prevent short circuits or electric leaks, and tests protective devices to promptly cut off power in case of anomalies, safeguarding both personnel and equipment. Proper commissioning also optimizes operating conditions, minimizes component wear, extends the generator’s lifespan, and ensures compliance with industry regulations and standards.   Important Notice:   Please be aware that all generators imported from us or overseas suppliers are shipped with liquids (oil, coolant, and diesel) drained out, in compliance with shipping company regulations. Therefore, before using the generator for the first time, you must refill it with the appropriate amounts of oil, coolant, and diesel.   1. No-Load Testing Before testing under load, newly purchased diesel generators should unde...

Diesel Generator Sets: Essential Knowledge, Classification, and Pricing Explained Diesel generator sets are essential backup power solutions widely used across industries including hospitals, construction sites, data centers, factories, and more.
