Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

MEDIUM VOLTAGE CURRENT TRANSFORMERS

In the permanent offer in DACPOL we guarantee the best quality and the safest products and solutions from the electrical measurements category. We offer an extensive assortment of medium voltage current transformers, including:

- GSK (F) - split-core current transformers - used for a variety of measuring, revenue metering (billing) and protection tasks.
- GSA (F) - cast-resin current transformers.
- IGW - medium voltage insulated current transformer for indoor application - for measurement and protection purposes in busbar systems of 24kV medium voltage switch-gear with rated primary currents up to 3000A,
- IGHF and IGWF outdoor head current transformer.
- UGZT - auxiliary power supply - required to ensure the energy supply for the operation of primary or secondary devices in a station, switchgear or substation. Typically includes: smart grid electronics, air conditioning, heating, lighting, power transformer cooling fans, station battery chargers (DC) and standard wall socket outlets.
- UGE, UGZ (single-pole and double-pole indoor voltage transformers) - medium voltage insulated voltage transformer - used for measuring and protection purposes - especially in medium-voltage switch gear up to Um = 24 kV.
- UGECAK.D1 and UGECAK.D2 - medium voltage insulated voltage transformer.
- UGEF - medium voltage insulated current transformer for outdoor application - used for measurement or protection purpose.
- DAC PW1 - auxiliary power supply for outdoor application - to ensure the energy supply for the operation of primary or secondary devices in a station, switchgear or substation.

Electrical measurements and devices category also covers an extensive choice of other products – we provide such elements like: current transformers, current probes, Rogowski coils shunts, probes, meters, transformers and other medium voltage current transformers. Our offer also includes network parameter analyzers as well as analog meters.

What is electrical measurement industry?

It is an industrial sector that includes control measurements of electrical quantities in circuits as well as measurements of other quantities in which electrical energy is used.

What is a current transformer and how does it work?

Current transformer (or C.T.) is a type of “instrument transformer” - aimed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary. They reduce high voltage currents to a much lower value, which provides a more convenient and safe way to monitor the actual electrical current flowing in an AC transmission line using a standard ammeter.

In the case of control measurements of electrical quantities in the circuits, the meters of such quantities such as voltage, intensity, resistance or power are directly connected to the circuit. For measurements of other quantities, a meter measuring, for example, a quantity such as temperature or number of revolutions must be provided with a transducer so that the measured quantity can be represented by means of appropriate units.

We distinguish three main types of current transformers: wound, toroidal and bar.

Current transformer – where to use?

- For proportional change of high voltage to the lower one.
- Used together with ammeters to provide a maximum secondary current corresponding to a full-scale deflection on the ammeter.
- Evaluation by using measuring devices with a narrow scale.
- They allow positioning the devices in a far distance from the controlled circuit.
