Ilahi Bakhsh was a Punjabi general. He served in the Sikh Khalsa Fauj for over forty years and was sometimes regarded as one of the best artillery officers, he entered the service of the army in 1802. Following a re-organization of the army in 1810, Bakhsh was transferred to a new artillery corps, the Fauj-i-Khas, led by Mian Ghaus Khan. In 1814 he was placed in command of a special wing of artillery named the Derah-i-Ilahi. In 1818 he assisted Misr Diwan Chand at the Battle of Multan, he was employed in the pacification of Hazara and Dera Ghazi Khan. He fought at the Battle of Nowshera in March 1823. In 1831 at the Ropar meeting between Maharaja Ranjit Singh and Lord William Bentinck, the Governor-General of India, he arranged a demonstration of his artillery as well as of his own firing skill in the course of evening entertainments and the review of troops. In the beginning of January 1844, he was removed from his command in suspicion of corresponding with Jawahar Singh and Suchet Singh but was restored to his command a few days later.

He was present at many of the battles during Second Anglo-Sikh War. He played a key role at the Battle of Chillianwala, one of the bloodiest British battles fought in India. Three days after the battle, Ilahi Bakhsh defected to the British due to a monetary incentive from the British; the defection of Bakhsh dealt a blow to the Sikh artillery and they capitulated to the British the following month at Gujrat. He died in the Battle of Sobraon in 1846, his sons Fateh Khan, Sikander Khan and Madad Khan all achieved distinction as officers in the Sikh Army. Sikander succeeded his father as Chief of the Artillery and inherited substantial properties in Lahore. Fateh died whilst fighting at the Battle of Mudki, Madad was killed at the Battle of Chillianwala, his great-granddaughter married the founder of the Unionist Party, Sir Fazl-i-Hussain

A voltage portal extends a voltage source to the outside of an electrical enclosure in an encapsulated non-conductive housing designed for a Non-contact voltage detector to sense voltage if placed into the voltage portal. A voltage portal avoids voltage exposure for workers by extending the voltage source points to the outside of electrical enclosures; each voltage point resides in an encapsulated non-conductive housing designed to ensure that a NCVD senses voltage if placed into the voltage portal. Because a voltage portal contains live voltage and mounts on the outside of an electrical enclosure, it must be robust to ensure long term safety; the UL enclosure type rating of the voltage portal must match the enclosure rating. Many maintenance workers carry NCVD AC voltage detectors in their tool belts; this portable device allows workers to check electrical conductors for live voltage without touching the bare wire. The NCVD can sense voltage when positioned close to the live conductor without making a hard-wired electrical connection.

A voltage portal is used to assist workers in creating an electrically safe work condition as part of a lockout-tagout procedure before beginning work on electrical or mechanical equipment.
