Planned maintenance ensures reliable electrical supply for Acute NHS hospital
When an acute NHS hospital in the Greater Manchester area recently needed to carry out planned ‘intrusive’ maintenance of its main LV switchgear, it called upon Quartzelec to carry out the task over two planned evening shifts.
The building that required the maintenance is dual supplied via two ABB 1250 KVA dry resin transformers that supply two LV panels. Work was carried out over two planned evening shifts, allowing one panel per evening to be fully isolated, with all affected circuits being re-supplied via the other panel.

The LV switchgear servicing, including the interrogation of all air circuit breakers, was achieved following a detailed switching program with assistance from the electrical site AP.

Detailed recordings of the protective devices, ratings and settings were included, and a full report summary was issued upon completion. This included an introduction, results section, and summary of the overall condition of the switchgear. Also included as part of the works was thermographic imaging, which was captured before isolating the supplies. All connections and torque settings were checked and inspected, and each cubicle was thoroughly cleaned. The client now has peace of mind knowing that its LV infrastructure is in good condition and remains fully compliant.

“It’s not unusual to be called in by NHS Trusts at short notice to investigate and resolve electrical issues,” said Andy Taylor, Supervisor for Quartzelec’s Building Services Maintenance team who coordinated the project. “We endeavour to address issues before they cause serious risk to the hospital and regularly go that extra mile for our customers to ensure they remain operating at optimum performance and within appropriate safety parameters.”

Quartzelec maintains a dedicated healthcare support team that can respond to critical issues, and all engineers are HTM 06-02 competent, plus collectively hold an array of safety and process compliance certificates needed to operate in specialist healthcare environments.
