Is active filtering a sustainable investment?

Absolute. In addition to preventing outages, you reduce energy losses (I²R losses) in your cables and transformers. This directly contributes [...]

Can harmonic contamination lead to sensor failure in the water treatment process?

Yes, high-frequency contamination can cause 'noise' on control cables and analogue signals (4-20mA). This leads to erroneous readings in your SCADA system, [...]

What is the difference between a Power Quality measurement and a NEN inspection?

An NEN inspection looks at the visual condition and basic safety of the installation. A Power Quality measurement looks at the 'invisible' health [...]

How do I recognise blind current on my bill from the grid operator?

If your installation has many inductive loads (motors) without compensation, you will see a post for 'reactive consumption' in kVArh. HyTEPS helps [...]

What is the installation manager's role in grid contamination?

The IV is responsible for safety and continuity. Grid contamination falls under the duty of care; if contamination is known to affect the [...]

Should active filters be placed centrally or decentrally?

This depends on the structure of the installation. In water boards, we often see decentralised filtering at the largest [...]

Why are arc simulations specifically important for WWTPs?

Treatment plants often have complex, outdated distributors combined with new generators. An arc simulation calculates the incident energy during a short circuit, [...]

How does Power Quality help combat grid congestion for water boards?

Filtering reactive power and harmonics reduces the total power consumption (kVA) of the installation. This frees up 'space' on [...]

What is the impact of variable speed drives on Power Quality within a pumping station?

AC drives are essential for efficient water management, but they also generate harmonic current pollution. This contamination can lead to resonances with the [...]
