Webinars

• Importance of critical switchgear and power quality equipment servicing
• How to understand manufacturers servicing recommendations and how this can be interpreted by insurance companies possibly impacting a claim.
• New technologies to improve switchgear service life and improve safety for electrical contractors working on site
• Air circuit breaker retrofitting and what does this mean for AS/NZS61439 compliance.
• Review of recent catastrophic Australian electrical switchgear failure case studies.
• What does a sustainable switchgear maintenance program look like for an end user.

NHP understands that your overload relays are a critical asset in your motor control system and we support that by providing you with the latest technology to maximise your investment. New technologies can improve and extend the operation of existing equipment and provide an immediate boost to productivity.

In this webinar we will discuss migrating from your legacy CEP7-ED1/EE Overload to the new CEP7-1 Electronic Overload Relay, which can help you to decrease downtime, increase speed to market, and optimise operations well into the future.

In this webinar, we will discuss how to achieve an installation selectivity level appropriate for the installation. Focus on settings, expected behaviours and incorporation of Zone Selective Interlocking principles. We will examine our priorities and apply design criteria based on these and look at realistic outcomes.

Webinar topics:

• How do I achieve an appropriate selective system?
• What is a Type A MCCB, what is a Type B?
• What is Zone Selective Interlocking?
• What are my design criteria and priorities?
• What is my realistic outcome?

This webinar will cover the following topics:

1. Product Identification
2. Concept of operation
3. Applications & sensor selection

Given increasing costs and environmental awareness, energy conservation is a growing concern, and the need for energy efficiency throughout a plant or manufacturing floor is a priority. As a result, more attention is paid to motor starting methods as a cost saving to the bottom line. Using just enough energy to start and run motors helps to control the demand charges imposed by utility companies by reducing the amount of wasted energy.

In this webinar we will discuss the use of Linear Speed Acceleration on SMC-50 Soft Starters from Rockwell Automation. You will discover how Linear Acceleration control offers the simplest and most consistent starting and stopping performance, whilst minimising electrical and mechanical stress on the motor and driven machine.

Hazardous areas exist in many industrial sites where motor control and protection is required, understanding what types of motor protection is allowed based on the type of Ex rated motor is critical in selecting and safeguarding equipment and site. In this technical webinar, we will be exploring the most common types of Ex rated motors that exist, and covering the general and additional requirements of the protection of these motors based on AS/NZS 60079.14.

In this webinar we discuss:

• Why we need Ex rated motors
• Common Ex motor rated protection methods
• General requirements for motor protection within a hazardous area according to AS/NZS 60079.14
• Additional requirements based on the motors Ex protection method according to AS/NZS 60079.14

Modern safety systems allow us to do more than just turn off the machine to reduce the risk of injury to the operator. In this technical webinar we explore the various safe stop and motion techniques such as safe speed monitoring, which aid in reducing risks associated with direct access to the machine.

In this webinar we discuss:

• Safety Functions and Monitoring
• Modes of use for machines
• Stand-still detection
• Safe stop techniques including Safe Torque Off
• Stop categories
• Drive based safe motion functions and instructions
• Application examples
