Generator Servicing and Testing at Distribution Depots

Client: Distibution company

Location: Nationwide

Products & Services supplied: Generator maintenance contracts Load Bank Testing

Project Description

Overview
A market leader in global logistics and international mail services relied heavily on generators to support essential services at each of its 28 UK depots.  To ensure the reliable provision of continuous power supplies, it turned to shentongroup to provide loadbank testing and ongoing support through a generator maintenance support contract.

Problem
Maintaining an advantage within the highly competitive distribution sector demands access to continuous power supplies.  With 28 depots throughout the UK, the client relies on its generators to power lighting, telecommunications equipment, computer systems and more.

In order to maintain dependable continuous power supplies, the company must have regular servicing and support of its generator sets and supporting AMF panels to guarantee the smooth and reliable switchover to backup power in the increasingly likely event of any mains power failure.

Solution
A regular servicing contract was awarded to shentongroup which included the servicing of the generators at all of the client’s 28 UK depots. As well as managing the regular servicing of the standby generators shentongroup was also contracted to carry out extended loadbank testing of each generator using a portable 1MW rated, variable loadbank.

Derek Barry, shentongroup’s Technical Director explained: “The loadbank allows us to test a standby power system under simulated load conditions and to verify its overall reliability and ability to perform under emergency power situations”.  Derek continued: “When the loadbank is used, the artificial load it provides tests the whole system to its maximum capacity and confirms the engine’s ability to provide the required power output over an extended period of time. The engine also benefits, as this type of testing removes the build-up of any carbon deposits from the pistons, engine casing and exhaust systems”.

Carrying out the annual service and having the assurance of a 24/7 callout facility is now an essential part of the company’s maintenance programme. The load testing is being carried out at the same time as the annual major service.  The alternator and control system (AMF panel) are also checked, and the voltage and frequency are monitored and recorded to check that output is within specification.

Outcomes
The client’s backup power system now operates at optimum capacity, thanks to regular servicing and loadbank testing.

Because shentongroup has a network of depots throughout the UK, the client is assured that, in the event of any technical issue or fault, a shentongroup engineer can be onsite at any of the client’s 28 locations rapidly.

Commenting on his experiences with shentongroup, the client’s Group Building Surveyor said: “We have been using shentongroup services since 1999 and they have always provided us with an excellent service.  They are very diligent in their maintenance and prompt with their reports”.
