EVALUATION OF IH COOKING HEATER (FOR WT310HE)

Overview

In recent years the buzzword “all electric” is becoming popular, which refers to kitchen appliances, water heaters, and other devices in the home all being supplied with electric power. Along with this, demand is growing for IH (induction heating) cooking heaters as a safer alternative to gas ranges. IH cooking heaters use large currents to generate strong thermoelectric power that is converted to heat. The large current flowing in an IH cooking heater can be input directly to the WT310HE without the need for current sensors or other devices, allowing measurement of voltage, current, power, waveform distortion (THD), and other parameters.
Measurements can be taken at intervals as short as 100 ms, allowing for high speed acquisition of power data on manufacturing lines.

Features

  1. Large current direct input: 40Arms.
  2. High Accuracy power consumption measurement:0.1% of reading.
  3. High speed update rate: 100ms interval with all channels.
  4. Harmonics (DC-50th order) and Total harmonic distortion (THD) can be measured.

The WT310HE has MAX. 40Arms range for testing large current equipment like IH cooking machine. It can measure voltage/current/Power and THD (Total Harmonic Distortion) at same time. Therefore, evaluation period of IH cooking machine becomes shorter.

On the other hands, in order to fit “frying pan and pot of all kind of metal material”, driven frequency of IH circuit becomes faster. The WT18000 is better for the evaluation because of its performance.
Feature of WT1800
Max current input range: 50Arms Max input channels: 6 Bandwidth: DC,0.1Hz to 5MHz Sampling frequency: Approx. 2MS/s

Customer Feedback

  • Easy to use.
  • it is possible that data monitoring of all measurement items and data recording by WTViewerFreePlus.
  • IH cooking heater can be input directly to New power meter without the need for current sensors.

Power Analyzers

Power Analyzers

A power analyzer measures electrical power characteristics of devices that generate, transform, or consume electricity. Also called power meters or wattmeters, these devices measure parameters such as true power (watts), power factor, harmonics and efficiency in inverters, motor drives, lighting, home appliances, office equipment, power supplies, industrial machinery and other devices. Power analyzers also enable engineers to minimize energy loss due to distorted, transient waveforms in power electronics such as inverters, motors, lighting circuits, and power supplies. 

Yokogawa, the world's leading manufacturer of electrical power analyzers, provides a broad selection to satisfy all requirements.
