RITZ has recently decided to concentrate on a core business of medium-voltage and low-voltage transformers, with the high-voltage transformer division being sold. The resources gained through this will be used for additional innovations and quality standards for medium and low-voltage products. Medium-voltage instrument transformers
We provide medium-voltage instrument transformers up to 72.5kV, for both indoor and outdoor applications. Of metal-clad or metalised design, they include burst-proof metering voltage transformers for railway vehicles. Low-voltage instrument transformers
RITZ offers low-voltage instrument transformers of up to 1.2kV. Current transformers for measuring and protection purposes
We provide a range of current transformers for measuring and protection purpose. These transformers include: Medium-voltage instrument transformer. Low-voltage instrument transformer. Cast-resin power transformer. Wound primary CT Auxiliary CT Summation CT Window type CT CT for switch fuses Tube type CT Window type CT for high currents Multi-range CT Split-core types for earth fault protection Split-core CT Special instrument transformers for measuring purposes
Our special instrument transformers for measuring include three-phase CT, laboratory current and voltage transformers, and voltage transformers. We also provide instrument transformers for bill / tariff metering, and damping inductance devices against ferroresonance. Cast-resin insulated power transformers
We provide cast-resin insulated power transformers of up to 40,5kV and 25MVA. Glass-fibre reinforced high-voltage coils and low-voltage coils
Glass-fibre reinforced vacuum technology (GVT) is used for high-voltage coils and optionally for low-voltage coils in order to guarantee the highest possible quality and reliability, and to avoid cracks or voids during manufacturing and service.
Applications include: Power distribution Rectifier drives Oil platforms / vessels Generator excitation Injection systems Transmitter systems Grounding systems Laboratory system Traction power systems (for trams, metros and railways) Turnkey medium-voltage and low-voltage transformers
We provide a wide range of transformer installation services, including disposal of existing oil and PCB transformers, and system start-up. Special transformers
In addition to their standard transformers, RITZ also produces special transformers for a variety of special applications: Injection transformers for ripple-control applications Reactors for ripple-control applications High-current transformers Earthing transformers Medium-frequency transformers Filter and blocking reactors Smoothing and inter-phase reactors Environmental, climatic and fire protective transformers
RITZ transformers are designed according to required international specifications like DIN/VDE or IEC. Furthermore they fulfill all climatic, environmental and fire protection requirements, including environmental class E2, climate class C2, fire protection class F1, and basic impulse level list 2.
The requirements for environmental protection are taken into account during the design of RITZ transformers. Characteristics include: Impulse voltage proof Partial discharge free Short-circuit proof Highest mechanical strength Cooling channels in HV and LV coils Pre-galvanised steel frame
Under the trading name RITZ Instrument Transformers, RITZ has been pooling its activities to gather new strengths since 1 August 2007. The tradition and knowledge of the parent company RITZ Messwandler Hamburg and the subsidiary RITZ Messwandler Dresden (TuR) have been united with the companies Wandler- und Transformatoren-Werk Wirges (WTW) and Messwandlerbau Bamberg (MWB) under this name. This merger unites a total of more than 200 years of know-how in instrument transformers production. Electronic instrument transformers and sensors
We provide voltage-sensoric electronic instrument transformers and sensors. They feature voltage up to 90kV, accuracy of 0.2%, and frequency from 0kHz to 10kHz.
RITZ also offers current-sensoric electronic instrument transformers and sensors. They feature current up to 24.000A, accuracy of 0.01%, and frequency from 0kHz to 10kHz.

The overseas corporations of RITZ Instrument Transformer in Austria (Marchtrenk), Hungary (Kecskemét) and China (Shanghai) strengthen the company’s position on the international market.
The RITZ Solid Insulated Bus-Bar System provides transmission services for higher currents and / or limited space requirements.
RITZ produces transformers in glass-fibre reinforced vacuum technology (GVT) for ratings up to 25MVA and 40.5kV voltage class for various applications.
RITZ supplies medium-voltage and low-voltage instrument transformers.
Instrument transformers are transformers, which convert high currents or voltages into measurable and standardised currents or voltages, which are proportional and in-phase to the primary signal.
On 12 December 2009 RITZ broke ground for a €2m project at Wirges, enlarging the production site for transformers to a total of 8,000m² thus doubling the production area and securing employment on site. As a result, final assembly can be relocated from Oberursel (near Frankfor
