22 INSPECTIONS Periodic comprehensive inspection Since these devices operate during abnormal conditions on the power system, the only way to ensure correct operation is by a periodic comprehensive inspection, maintenance, tests and calibration programs. Safeguard the protection functionality Bakker Sliedrecht offers brand independent protective relays inspections and test programs that inspect all protection systems of low-and-high voltage installations that ensure an automatic stop in case of emergency. Amongst others, the following parameters and functionalities are checked by current and voltage injection with our calibrated portable protective relays testing kit. Over-under frequency Over-under voltage Over-under current Reverse Power Protective relays inspection Bakker Sliedrecht can replace defect parts of common brands and types immediately. Ensure the safety of your installation Protective relays are attached to electrical installations to detect abnormalities in the current, voltage, and frequency, flowing in the electrical system. When an abnormality is detected, it will send a signal to a trip coil on a particular device, such as a circuit breaker, that is designed to interrupt the circuit, thus limiting damage to equipment and personnel. If the protective relays are not monitoring or measuring properly, they can cause nontripping or false tripping. This can result in dangerous situations and damage to critical component, or unnecessary downtime of critical equipment. Ensure the safety of your staff and installations Prevent unnecessary downtime For low-and-high voltage installations Inspection of all brands and types Immediate replacement of components if necessary Certified and calibrated measurement equipment Report including conclusions and recommendations 40 bakkersliedrecht.com 41

23 INSPECTIONS Maximize uptime with online measurement and direct replacements To optimize the reliability and performance of your electrical system while keeping your maintenance cost and time efficient it is essential to determine the possible fault locations in an early phase. Bakker Sliedrecht can assist you with preventive maintenance and inspections. Partial Discharge measurement is an inspection that reveals the weak points in the isolation of your high voltage cable. Our technicians comply with IEC 60270:2000/BS EN 60270:2001 standards. Bakker Sliedrecht will measure the partial discharge of cables during operation (online) to determine their condition without any downtime. Online partial discharge measurement on high voltage cables The collected data is benchmarked within a worldwide database and analyzed by Bakker Sliedrecht to discover trends and provide a lifetime expectation. The report categorizes HV cables in five categories ranging from healthy to immediate replacement needed. Bakker Sliedrecht can also take care of all follow-up actions, such as the replacement of cable sections and advise on further maintenance planning. With replacing only the cable sections that are necessary, lower costs are made. Prevent high unexpected costs and damage to your high voltage cables and installation Failure of the high voltage (HV) cable network in your installation can lead to unexpected downtime and extra costs for your organization. These costs include urgent corrective maintenance costs, production losses and stress to find the origin within the total (underground) cable network. One of the causes of cable failure is Partial Discharge. Partial Discharge is a dielectric breakdown caused by small deterioration (cracks) which is to small to cross between the conductors. This will lead to eroded insulation (usually forming a tree-shaped pattern of detoriation). In the end this can lead to a complete breakdown of your HV cables and installation, damage to your installation or even fire and explosions. Improved reliability and safety of your installation by minimizing costly unexpected breakdowns Measurements during operations (online) without disrupting your operation Discover detoriation trends in the insulation Benchmark with similar cables worldwide Minimize unnecessary cost by proposing only replacements of segments of your cable Calibrated measurement equipment Report including recommendations on replacement of cable sections 42 bakkersliedrecht.com 43

24 INSPECTIONS performing measurements during operation to identify disturbances. These disturbances can take many forms ranging from: harmonics, voltage sags/swells/ unbalances, flicker, and transients etc. Our specialized measurement equipment enables us to accurately monitor and record voltage, current, power, harmonics and many other relevant parameters. Short term testing can be used to record the behavior of specific equipment. Long term testing can be used to record ongoing power quality parameters and detect intermittent electrical supply issues. Cost-effective power quality power mitigation Analyzing power quality is an effective way to identify electrical disturbances without having to shut down the system. Once disturbances have been identified, Bakker Sliedrecht can advise and implement cost-efficient solutions for power quality mitigation. We can make sure that the power quality level is compliant with standards that are required by classification. The investments for solving power quality issues often have a quick return on investment. Power Quality Analysis on Low Voltage electrical systems The impact of poor power quality Are you experiencing harmonic distortion problems after changes, like a retrofit, to your installation? Poor power quality results in extra costs due to excessive energy use, unscheduled stops, increased maintenance, and replacement of components that have aged too quickly. End use equipment, such as automation systems or computers, have become more sensitive to disturbances in the power quality that arise both on the supplying power system and within the electrical system. Furthermore, equipment is more interconnected in networks and industrial processes so that the impacts of a problem with any piece of equipment are much more severe. Calibrated measurements Minimize unexpected downtime Minimize energy losses Prevent lifetime reduction of electrical equipment Measurements during operation Fast measurements of high speed transients Report including recommendations for corrective measures Bakker Sliedrecht can take care of complete power quality mitigation Power quality analysis can be part of a predictive maintenance program 44 Analyze your power quality to discover disturbances Bakker Sliedrecht can analyze the power quality of your electrical installation by bakkersliedrecht.com 45
