TNT’s generators support all essential services at its depots — including lighting, telephones and IT equipment.
Merlin has also been contracted to carry out extensive load testing of each generator using its variable-load bank, which enables a standby-power system to be tested under various simulated load conditions to verify its overall reliability and ability to perform.
When the load bank is used to test a standby generator, the whole system is tested to maximum capacity, and the ability of the engines to deliver the required output over an extended period is confirmed. Such test also removes any build-up of carbon deposits from the pistons, engine casing and exhaust systems.
The alternator and control system are also checked, and the voltage and frequency are monitored to check the output is within specification.
