Insulation resistance test immersion heater
NettetTimed ratio tests are used to detect insulation resistance and include the polarization index (PI) and dielectric absorption rate (DAR). The Fluke 1555, Fluke 1550c, and Fluke 1587 FC automatically calculate the PI … Nettet17. feb. 2024 · The Class I heaters have only one thermostat which works in 1-degree increments. Class I electric Heaters can therefore only react to a temperature change of 2 or 3 degrees, which in today’s engineering terms, is a very poor responsiveness. The Class II IntelliHeat radiators will react to one tenth of a degree, making them ten times …
