Registration “Getting Started With SKM Power Tools” open

Registration for the training course Getting Started With SKM Power Tools is open now. The training will take place November 26 – 27, 2020 in CitizenM Rotterdam Hotel, the Netherlands. The number of participants is limited.

Intelligent Electronic Device (IED)

Microprocessor-based voltage regulators, protection relays, circuit breaker controllers, etc. with the capability of serial communication with other devices are Intelligent Electronic Device (IEDs). This post contains a brief overview of IED electrical interfacing, functionality, HMI and setting studies.

Selecting a Voltage Transformer (VT)

If the ratio, burden, class and optionally voltage factor are selected, the voltage transformer (VT) or potential transformer (PT) has been specified basically. Of course additional requirements like type, frequency, environmental conditions should also be specified.

Selecting a Current Transformer (CT)

If the current ratio, burden and class are selected, the current transformer (CT) has been specified basically. Of course additional requirements like type, frequency, isolation level, maximal short circuit current and environmental conditions should also be specified.

General information about power systems on the web

Today the web offers quite a lot of general information about electrical power engineering, that I use gratefully. Below are some interesting websites.

Protection relays then and now

In the past, manufacturers assembled generator protection systems from electro-mechanical and later electronic relays. Each relay contained only one or some dedicated protective functions.

Generator protection functions

The generator protection functions with their English and Dutch description, including ASCI/IEEE device codes and IEC symbols, are implemented in a table.

Engineering & Consultancy

I like to use my knowledge, experience and insight to proceed or solve my customer’s power system issues. Of course my designs, calculations and advises are based on power system engineering methods and common practice. My competences and specialisations are: Medium Voltage Power Systems (3 – 25 kV) Generators, Power Generation Protection Systems & Relays Excitation Systems, […]
