Generator Brush Collector Ring’s Arc Flash Hazard, A Safety Concern!

Generator Brush Collector Ring’s Arc Flash Hazard, A Safety Concern!

For some types of generator exciter systems, collector rings and brushes are used to provide energy from the exciter to the rotating field. The brushes wear down and constantly need to be replaced with the unit on-line and while brush/ring assembly is still energized, a risky and unsafe maintenance operation and may cause a serious harm. A potential shock and arc-flash hazard. This presentation addresses the important and dangerous maintenance of worn-down collector rings and brushes, electrical safety, lack of standards and guidelines, and a first possible calculation method.

AC and DC Arc Flash Methods for Renewable Energy Systems

This presentation will address the difficulties and lessons learnt on performing arc flash analysis using available methods (outside the voltage limits of IEEE 1584-2018 standard) on a 2.3 MW PV generation facility. The analysis includes system modeling, short-circuit, arc flash (both AC and DC) using various applicable calculation methods that best fit this application along with available tools in ETAP and generating worst-case arc flash deliverables.

AC Arc Flash Analysis for a Datacenter Network in Italy to determine the PPE for Workers using ETAP

AC Arc Flash Analysis for a Datacenter Network in Italy to determine the PPE for Workers using ETAP

Arc Flash Analysis was performed on a new datacenter building in Italy, calculating Incident Energy and Arc Flash Boundaries at several locations, from the main 15kV distribution switch gears down to the main LV distribution switchboard and diversionary panel boards in each segment. The studies were performed using ETAP Arc Flash software to identify the correct personal protection equipment (PPE) for engineering staff during maintenances operations. Standards applied include: NFPA 70E-2021, IEEE 1584-2018, IEC 60909 (2016).

Modeling and Analysis of a Microgrid for a Wastewater Treatment Plant - AECOM

Modeling and Analysis of a Microgrid for a Wastewater Treatment Plant - AECOM

Engineering and operation objectives of mission-critical facilities require a reliable and secure power supply system. Microgrids have become the leading technological solution for a resilient and sustainable supply of electricity for critical infrastructures. This paper presents ETAP-based power system studies of a microgrid designed for a mission-critical facility, a wastewater treatment plant (WWTP). The microgrid consists of a behind-the-meter (BTM) solar photovoltaic (PV) system, a battery energy storage system (BESS), a combined heat and power (CHP) generator, and standby diesel generators. We modeled this microgrid by leveraging the ETAP software and performed power system studies for both grid-connected and islanded modes of operation. Several scenarios were created based on different loading conditions and power source combinations, which are utilized to validate the power system studies. We will discuss the model of the power system investigated, operational strategy and sequences of operation, findings, challenges, lessons learned, and future works.

Powering IT/OT Convergence for DC Management in Data Centers with ETAP

Powering IT/OT Convergence for DC Management in Data Centers with ETAP

Electrical infrastructure can only be managed by including both equipment and data. Transforming electrical data to information and knowledge for decision-makers of mission-critical facilities requires IT-compatible software with the latest technologies’ integration capabilities. This presentation shows how ETAP enables end-users to achieve sustainable operations in their critical facilities by fulfilling OT/Site Management and IT Management requirements. ETAP’s unique features are configured with respect to data center topology and sustainable operation principles. These features are enriched as we have positioned ETAP in the corporate environment of end-users, where their corporate IT standards, services, and tools are integrated. As the title suggests, both OT and IT protocols are commissioned together, and the management of electrical infrastructure is powered by IT services via ETAP.

Upgrading Bokaro Steel Plant's existing Supervisory Load Control Centre System with ETAP SCADA

Upgrading Bokaro Steel Plant's existing Supervisory Load Control Centre System with ETAP SCADA

Steel Authority of India Limited (SAIL) is one of the largest steel-making companies in India and one of the Maharatnas of the country’s Central Public Sector Enterprises. ETAP was selected to upgrade the existing SLCC (Supervisory Load Control Centre) System for Power Distribution of Bokaro Steel Plant. This presentation will give insights into the project scope and deployment: The SCADA/PDMS system shall monitor and control the Distribution & Sub-Distribution stations and achieve the SCADA/PDMS functions, integrated with the SLCC control center. Bokaro Steel Plant (BSL) is having a client/server architecture-based SCADA System for monitoring and controlling of generation, import, and distribution of power through SLCC Control room at MSDS-I. The SLCC system is also connected to a central SLCC system located in Kolkata. RTUs for substations will be installed in various locations which are connected through a dedicated fiber-optic network to the server.

How ETAP was utilized  to  expand  the Electrical System at the Tailings Dam Copper Mine in Peru

How ETAP was utilized to expand the Electrical System at the Tailings Dam Copper Mine in Peru

As part of their Tailings Dam Expansion project, a large copper mine in Peru required to have several studies performed in their electrical system. As loads were added and the topology of the system was changing, the client wanted to ensure that their electrical system would be able to handle the new loads and operate reliably and efficiently. Electro Integra S.A.C. was hired to perform Load Flow, Short Circuit, Relay Coordination, Motor Starting and Optimal Capacitor Placement studies. ETAP was used as the tool to perform all the studies because the client has been using ETAP for over 20 years. Since 2000, Electro Integra has partnered with ETAP to bring their software solutions to the Peruvian market. Continuous development and investment in ETAP Solutions has kept them as the de facto standard for power system analysis for all types and sizes of electrical industries.

Ground Grid Design with ETAP in a Steel Plant in Mexico - EPSOL

A Ground Grid design project is presented in a steel plant in Mexico and the objective is to reduce the step and touch potentials in the area of ​​electric arc furnaces of 50 kA connected to transformers of 13.8/0.6 KV and that in the moment of melting, they create dangerous currents for the workers who operate these furnaces. The project is executed from the field measurements of the resistivity of the ground and the design of the ground grid with the ETAP finite element method (FEM) and the construction of the grid is executed up to the foot of the ovens, thereby reducing said potentials to safe values ​​for the workers, contributing to a safer work area.
