Electrical Controls & Instrumentation

Drilling Control System

The Drilling Control System (DCS) is at the heart of your drilling rig operations. At Jelec we focus on research that improves the operating environment. Our DCS provides safe operations, user friendly controls and optimized efficiency of the equipment and drilling process.

An open-architecture is one of the main features for the system. The capability to customize applications to suit your requirements and for rig personnel to make modifications to the system without requiring Jelec personnel on-site. All system data is available for on-site or remote monitoring and interface with any 3rd party system.

Our system can be customized to suit your specific requirements (e.g. condition monitoring based on motor current and vibration is available for predictive maintenance).

Drilling Automation

Automation enables higher operation efficiency and drilling optimization. A large section of our research and development at Jelec is focused around automation. Each task we can safely automate allows the driller to focus more on the real task at hand: drilling the well. Automated drill floor or drilling processes usually require a single manufacturer package. The Jelec DCS offers a fully integrated automation package for different brands of equipment according to your preferences. We designed a user friendly HMI to display meaningful alarms and status enabling the driller to easily track the progress of the automation system.

Power Distribution


Jelec complete engineering solutions reduce operational costs, increase safety, enhance drilling and equipment optimization / performance. Jelec’s focus is on the manufacturing of custom-designed power solutions including power distribution, automation & control system and power control room (PCR). This enables smooth integration between all aspects of a project (eliminating finger pointing that comes from multi-supplier solution).

Power Management System

Jelec Power Management System ensures the best energy consumption in class for safest and most economic operation of the rig. Its task is to make sure that the electrical system is safe and efficient. If the power consumption is larger than the power production capacity, load shedding is used to avoid blackout. The power management will also guide the operator to select the optimal number of engines to be running depending on the operating conditions.

Variable Frequency Drives

We offer a compact designed and developed range of Variable Frequency Drive Systems with latest technology, high performance, and a user friendly concept. We have the experience and know how to provide you with the best drive for your application. The drive system is engineered utilizing a common DC bus design. Grouped drives are available for the most cost-efficient and functional drive system architecture.

Rig Energy Storage System

The system provides storage of electrical energy using state of the art Lithium Ion LTO Batteries to load balance the engine operation on drilling rigs (drawworks peak shaving) and to optimize the number of running diesel generators in order to reduce fuel consumption and emissions.
