Operation and Maintenance After the Site Is On Air

A site that passed acceptance in March can be quiet by August: a fan full of dust, a battery drifting, an earth pit dried out, a generator that nobody has started since the tests. SARBS lists operation and maintenance as its own service because install and care are different kinds of work.

What a useful visit looks at

• Rectifier alarms, module load share and the 54V bus, not only a green lamp on the door.
• Battery voltage, temperature and, where the display has it, the state information SARBS builds into the plant.
• Cabinet filters, seals and any sign that water took the lower gland.
• Earth connections and surge devices, which fail invisibly.
• Generator start, if the site has one, under a controlled test rather than during a real outage.

Maintenance informed by monitoring

Blind monthly visits miss the fault that happened on day three. Built-in RMS and the iThink research line exist so the visit list is ranked. Tenant current that jumped last week is a reason to go. A battery that looks like last month is a reason to stay on the planned round. SARBS publishes three hundred trained resources and warranty support on a very large battery base. That only helps if someone is contracted to use them.

O&M sits on the services page with regeneration, rollout and radio work. Operators who want the power plant included, not only the radio, should say so in the scope. The Gulshan office can start from the site list.
