Energy Measurement Technology

Optimizing energy consumption requires comprehensive energy measurement. WAGO’s portfolio has energy meters that simplify this task while offering several key advantages.Your Benefits:Compliance with the MID Directive 2014/32/EU allows consumption billing applicationsM-Bus and Modbus RTU interface and two S0 pulse outputsPush-in CAGE CLAMP^® and lever save time at every stageReal space savings with 2 DU: 35 mm (2PUCT) and 4 DU: 72 mm (4 PU and 4 PS)Full transparency with an illuminated full-format displayIntuitive configuration with touch-sensitive controls and configuration app via Bluetooth^®

The power measurement modules in a DIN-rail mounting enclosure offer the ideal solution for measuring currents and voltages in a three-phase supply network remotely from the control level.

Your Benefits:

• Various device variants for optional connection of current transformers or Rogowski coils

• Slot for microSD cards for storing measurement data

• Compact DIN-rail-mount enclosure

• Communication via Modbus RTU and pulse output

Besides current and voltage signal conditioners which record DC and AC currents and voltages, this impressive range also includes a power measurement module that can measure current and voltage in parallel, convert them to power and output them as an analog standard signal.

Your Benefits:

• Measure DC or AC voltages up to 300 V in a width of just 6 mm

• Common the supply voltage via jumpers that can be used across the entire range

• Versatile configuration

Plug-in current transformers for billing measurements are inductive, single-conductor current transformers. Due to the measurement principle used, these current transformers are exclusively designed for AC network applications.

These plug-in current transformers comply with the conformity assessment procedure (module D) and can be used for billing.

Your Benefits:

• Readily combinable with the energy meter with transformer connections

• Screwless CAGE CLAMP^® connection technology

• Approved for billing purposes

WAGO’s plug-in current transformers are suitable for round conductors and current bars. They are available for primary currents from 50 to 2500 A.

Your Benefits:

• Screwless CAGE CLAMP® connection technology

• Quick-mount kit for easy and cost-effective installation

• Tremendous versatility thanks to several mounting options

• Easy transformer short-circuiting via redundant secondary terminals S1 and S2

• UL listed

WAGO’s plug-in current transformers are available in two sizes with up to 64 A of primary rated current and the proven picoMAX^® connection technology.

Your Benefits:

• Easy secondary cable installation via pluggable picoMAX^® connection technology

• Space-saving use directly above the circuit breaker

• UL listed

• Convert 35 A or 64 A to 1 A

• Flexible mounting options via separately available mounting carrier

WAGO’s split-core current transformers are ideal for retrofitting existing systems and have the great advantage of being mountable without interrupting the measurement line.

Your Benefits:

• A split measurement core allows installation without interrupting the primary conductor

• Pre-assembled secondary cable

• Easy and cost-effective installation via cable ties

The Rogowski coils are closed air coils with a separable coil body and a non-magnetic core, which reliably convert alternating currents.

Your Benefits:

• Reduced footprint – ideal for measuring high currents via split core

• Easy to use via bayonet lock and anchor points for cable ties

• Higher security via sealable bayonet lock

• Ready for worldwide use in many industries, thanks to UL listing

• No limitation of the primary current, since saturation effects do not occur

The current and voltage tap is a combination of current transformer and voltage tap. It can be easily and quickly mounted in the jumper slot of the high-current rail-mount terminal blocks.

Your Benefits:

• Power data can be directly tapped into the power supply

• Complies with accuracy class 0.5 for exact measurement results

• Fused voltage path protects downstream measurement devices

• Integrated short circuit option

Voltage taps easily and safely tap the measurement voltage in existing systems. Conductor contact is made via IDC connection for reliable voltage tap-off.

Your Benefits:

• Integrated fuse to protect downstream measurement devices

• Suitable for insulated conductors up to a cross-section of 16 mm²

• Quick and easy mounting on current bars via clamp mount or M6/M8 mount

For the design, installation and setup of the new test laboratory for high-voltage and high-current testing at Hitachi Energy’s global technology center, the engineering firm IDEAS relies on current and voltage taps, as well as high-current rail-mount terminal blocks from WAGO.
