 DG सेट चलते चलते बंद हो जाये,क्या करे? 

DG set बंद होने के कारण निचे दिए गए हैं। उनको चेक करके DG की समस्या ठीक की जा सकती है

1. Malfunction in fuel system -  ईंधन प्रणाली में खराबी

फ्यूल टैंक चेक करे या खाली है तो उसे भरे |

2.Obstruction in fuel pipe - ईंधन पाइप में रुकावट

फ्यूल पाइप चेक करे | लीकेज, कोई रुकावत हो  तो, उसे क्लियर करे या पाइप चेंज करे |

3.air exist in fuel system - ईंधन प्रणाली में हवा मौजूद है

मैनुअल पंप द्वारा एयर को निकले |

4. Obstruction in air filter - एयर फिल्टर में रुकावट

एयर फिल्टर साफ करे या बदले

5. Sudden increase of Load - लोड का अचानक बढ़ना

लोड को कम करे |

6. Nozzel needel was bitted - नोज़ल की सुई कटी

DG set fuel consumption calculation ईंधन की खपत की गणना की

Diesel generator ईंधन की खपत की गणना की

डीजल जनरेटर में एक यूनिट उत्पन्न करने के लिए डीजल कितना खपत करता है
गणना करने के लिए, हमें तीन मान चाहिए-

1. उपभोक्ता डीजल
2. KWH उत्पन्न करें
3. डीजल दर

यूनिट चार्ज प्रति kwh = उत्पन्न kwh / खपत डीजल X डीजल दर
