Kamstrup 162M/382M 2 General description Kamstrup 162M and 382M are a generation of directly connected electricity meters for the measurement and registration of electrical energy. The meters are full-electronic without movable parts. Thus, energy registration is not affected by shock and impact during transportation and mounting. Furthermore, measurements are correct, no matter the physical mounting direction.
TECHNICAL DESCRIPTION Kamstrup 162M/382M 2.2 Construction The meter is designed as a three-piece plastic construction, consisting of housing, verification and meter covers, all parts made of fire resistant plastic. The verification cover protects the metrological functions. It is not possible to open the verification cover without breaking the metrological seal.
Kamstrup 162M/382M 2.3 Meter types Kamstrup’s direct meters are available in different variants depending on the application for which they are used. As default, in addition to many other functions, the meters are provided with debiting logger, event loggers, voltage quality measurement, tamper detection, and the possibility of using up to 8 tariffs. Furthermore, the meters can be supplied from the factory with internal disconnect function for disconnection and connection of the consumer’s supply, configured for the measurement of energy types in all 4 quadrants, with integrated radio...
The four or five digits of the ROM CRC appear as one number resulting from the checksum calculation. 3.2 Registers Kamstrup’s direct meters are constructed as 4-quadrant meters, which provide safe registration of various measured data such as imported and exported energy for both active and reactive energy, tariffed energy, power, voltage and current.
TECHNICAL DESCRIPTION Kamstrup 162M/382M A+ (1.8.0) Active positive energy consists of active energy from quadrants 1 and 4. A- (2.8.0) Active negative energy consists of active energy from quadrants 2 and 3. R+ (3.8.0) Reactive positive energy consists of positive inductive energy from quadrant 1 and positive capacitive energy from quadrant 2.
TECHNICAL DESCRIPTION Kamstrup 162M/382M Reactive positive energy. Positive inductive energy from quadrant 1 and positive capacitive energy from quadrant 2 are displayed in kvarh. Reactive negative energy. Negative inductive energy from quadrant 3 and negative capacitive energy from quadrant 4 are displayed in kvarh.
No register values in the meter will decrease due to inverse current flow, no matter of meter configuration. Total summation adds all contributions to the positive register whether one or all are negative. Kamstrup Generation M meters doesn’t support this calculation method for the main energy registration, but have a additional register for this called “A1423”.
TECHNICAL DESCRIPTION Kamstrup 162M/382M 3.2.5 Power registers The meter registers the current power (instantaneous power) in all four qudrants. Registration of active and reactive Power in the meter use same individually Import/export calculation method as in the case of energy measurements.
The status indicators are reset when the source to the indication disappears. Errors in digit number 2, 4 and 5 will in most cases be permanent and requires the meter to be returned to Kamstrup. In Figure 4 an example of the register shown in the display is illustrated.
TECHNICAL DESCRIPTION Kamstrup 162M/382M The time is adjustable via the configuration program METERTOOL for kWh meter or via reading system. It is possible to use daylight saving time with corresponding preprogramming of shifting dates, see more in section 10.2.4. 3.3.2 Backup The meters can be supplied with either a non-rechargeable unit (battery) or a rechargeable type (supercap).
TECHNICAL DESCRIPTION Kamstrup 162M/382M 3.5.1 Voltage measurement The RMS voltage measured per phase with average determination every second forms the basis of the registration of overvoltage, undervoltage, and voltage failures. The voltage per phase can be displayed with an accuracy corresponding to the meter’s class.
TECHNICAL DESCRIPTION Kamstrup 162M/382M 3.5.3 Registration of voltage failures Voltage failures on one or more phases lasting longer than the configurable time periode (t ) are registered in the event logger with time stamps at voltage dropout (t ) and voltage recovery (t ) in Figure 6.
Readout can take place by means of the open standard DLMS or Kamstrup's own protocol KMP. The data format at readout depends on whether absolute values or relative values are read out. The format of absolute values follows the format in which data is registered (7.2), whereas the format of the relative values is [3.2] (XXX.XX)
Page 20
TECHNICAL DESCRIPTION Kamstrup 162M/382M The registration interval follows the integration period, and the integration period can be changed after the commissioning. IMPORTANT: If the integration period is changed, the load profile logger is deleted. The logging depth of the load profile depends on the configuration of energy type and integration period for the meter.
TECHNICAL DESCRIPTION Kamstrup 162M/382M 3.6.4 Analysis logger The analysis logger allows the client to configure the registers to log and the log interval. Up to 16 simultaneous registers can be chosen. The log interval can be configured to 5, 15, 30 or 60 min. or 1 day. The logging depth of the analysis logger varies from 7 days to approx.
Internal errors are indicated by a warning triangle in the display and cannot be reset without the meter being returned to Kamstrup A/S. The status logger registers with time stamp whether the meter has been exposed to magnetic influence or the meter over has been dismounted (access control).
TECHNICAL DESCRIPTION Kamstrup 162M/382M 3.6.7 Event logger for voltage quality Voltage failures are possible on one or two independent phases or on all three phases. The lmeter registers voltage failures that last longer than minimum 1 second. No matter how many phases the voltage failure applies to, the time of the voltage dropout will be registrered, and it will also be registered when the voltage returns, as described in Figure 6.
